Best eSIM for International Travel 2026

Picture this: you have just landed at a new airport after a long international flight. You are exhausted, slightly disoriented, and desperately need Google Maps to find your hotel. But your phone shows no signal because your US carrier charges $10 per day for international roaming and you forgot to activate the plan before departure. You spend the next 30 minutes hunting for an airport Wi-Fi password, joining a queue at a local SIM card kiosk, and struggling to communicate with a vendor who speaks a different language.

This scenario plays out thousands of times every day at airports around the world. And in 2026, it is completely avoidable. The rise of eSIM technology has fundamentally changed how international travelers stay connected – making the experience faster, cheaper, more flexible, and significantly less stressful than any of the traditional alternatives.

According to global technology intelligence firm ABI Research, eSIM sales are expected to exceed $544 million in 2026, growing by 11% compared to the previous year. This is not a niche technology for tech enthusiasts anymore. It is the mainstream standard for international connectivity, adopted by millions of travelers across every age group and travel style.

For families, NRI travelers, and first-time international visitors from the USA, understanding eSIM technology in 2026 is not just useful – it is essential. This complete buyer’s guide covers everything you need to know: what an eSIM is, how it works, how to set it up, which providers are best for different travel destinations, how much it costs, and why Global Holidays USA recommends Holafly eSIM to all its travelers heading abroad.

What Is an eSIM and How Does It Work?

An eSIM – short for embedded SIM – is a digital version of the traditional physical SIM card that has powered mobile phones for decades. Unlike a physical SIM, which is a small plastic card that you insert into a slot in your phone, an eSIM is a tiny chip soldered permanently into your device’s motherboard at the time of manufacture. You cannot remove it, lose it, or accidentally drop it down a drain at a foreign airport.

The key innovation of eSIM technology is that it can be reprogrammed remotely. When you buy an eSIM plan from a provider, you are not receiving a physical card in the mail. Instead, you receive a QR code or a download link via email. Scanning that QR code with your phone’s camera writes a new carrier profile onto the embedded chip – effectively installing a new SIM card without any physical interaction whatsoever. The entire process takes less than five minutes from purchase to activation.

Your phone can store multiple eSIM profiles simultaneously – in many cases up to eight or more – and switch between them easily from the settings menu. This means you can have your regular US number active on one profile for incoming calls and texts, while using a separate eSIM data plan for internet access in Europe, Japan, or wherever you happen to be traveling. You get the best of both worlds: your normal phone number stays active, and your data costs stay low.

The Technology Behind eSIM: GSMA Standards

eSIM technology is governed by international standards set by the GSMA (GSM Association), the global trade body that represents the interests of mobile network operators worldwide. These standards ensure that eSIM profiles from any certified provider can work on any compatible device from any manufacturer – whether that is an iPhone, a Samsung Galaxy, a Google Pixel, or any other eSIM-compatible smartphone. The standardization means that when you buy an eSIM plan from Holafly for your trip to Europe, it will install and activate correctly on your iPhone 15 the same way it would on a Samsung Galaxy S25.

How Does an eSIM Work for International Travel? Step by Step

Understanding how an eSIM works for international travel removes all the mystery and makes the process feel simple and natural. Here is the complete journey from purchase to connection.

Before You Leave Home

The first step is purchasing your eSIM plan from your chosen provider’s website or app. You select your destination country or region, choose the duration of your plan (typically ranging from 7 days to 30 days), and select the amount of data you need (from 1GB for light usage to unlimited plans for heavy users). After payment, the provider sends a QR code to your email address, usually within a few minutes.

You then open your phone’s settings, navigate to the cellular or mobile data section, select the option to add a new eSIM, and scan the QR code with your camera. This installs the carrier profile onto your device. At this stage, your eSIM is installed but not yet active – it will only begin using data once you arrive at your destination and connect to a local network. The validity period of the plan starts from your first connection, not from the moment of installation.

When You Land Abroad

The moment your plane lands and you switch off airplane mode, your phone automatically searches for available networks. Your eSIM is configured to connect to partner networks in the destination country, and in most cases, the connection happens seamlessly within a few seconds – no action required from you. You open Google Maps, it loads immediately, and you navigate to your hotel with the calm confidence of someone who knows exactly what they are doing.

If automatic connection does not happen immediately, a quick restart of your phone almost always resolves the issue. Most eSIM providers also offer 24/7 customer support via chat or email for any connectivity issues that may arise during your trip.

Managing Your eSIM While Traveling

Once connected, you can monitor your data usage through the provider’s app or through your phone’s built-in data usage tracker in settings. If you are running low on data, many providers allow you to top up your existing plan with additional gigabytes or purchase a new plan for an extended stay, all from within the app without any additional setup. When you return home, simply switch your phone back to your regular US carrier profile and your normal service resumes instantly.

eSIM vs Physical SIM vs International Roaming: Which Is Best?

There are three main options for staying connected when you travel internationally from the USA. Understanding the genuine advantages and limitations of each helps you make the right choice for your specific travel situation.

International Roaming with Your US Carrier

International roaming is the simplest option in terms of effort – you do nothing, and your existing US phone number works abroad. However, the cost is a significant drawback. Major US carriers typically charge between $5 and $15 per day for international roaming packages, which means a two-week Europe trip for a family of four could cost between $280 and $840 in roaming fees alone – before a single attraction ticket is purchased. Data speeds can also be throttled on roaming plans, and coverage in rural or less-visited areas is often poor.

Local Physical SIM Cards

Buying a local SIM card at your destination is often the cheapest option for extended stays in a single country. A local SIM in France, Japan, or Thailand typically costs $10 to $20 and provides excellent local coverage. The downsides are significant, however. You need to find and visit a SIM card kiosk at the airport or a local store upon arrival, navigate potential language barriers, deal with registration requirements in some countries (Japan and South Korea, for example, have strict registration requirements for SIM card purchases by foreign visitors), and carry an additional physical card. If you lose your phone, the SIM is gone. And if you are visiting multiple countries, you need a new SIM for each one.

eSIM for International Travel

An eSIM eliminates every practical inconvenience of both alternatives. You purchase and install it before you leave home. It activates automatically when you land. It works across multiple countries on regional or global plans without any card swapping. It does not require a store visit, a language negotiation, or a registration form. It keeps your US phone number active for calls and texts while providing affordable data. And in 2026, the pricing has reached a point where eSIM plans are competitive with local SIM cards in most destinations while being dramatically cheaper than carrier roaming.

For most international travelers from the USA – and particularly for families traveling to multiple European countries, NRI travelers visiting India, and tour group participants traveling with Global Holidays USA – an eSIM is the clear, practical, and cost-effective choice in 2026.

Is Your Phone eSIM Compatible? How to Check

Before purchasing an eSIM plan, the first thing you need to confirm is whether your phone supports eSIM technology. The good news is that if you own a smartphone purchased in the last three to four years, there is an excellent chance it is already eSIM compatible.

eSIM Compatible iPhone Models

Apple began introducing eSIM support with the iPhone XS, XS Max, and XR in 2018. Every iPhone model released since then supports eSIM, including the iPhone 11, 12, 13, 14, and 15 series in all variants. From the iPhone 14 onward, Apple removed the physical SIM card slot entirely from US-market models, making eSIM the only option for connectivity on these devices.

To check if your iPhone supports eSIM, go to Settings, then tap General, then About. If you see an option labeled EID (Embedded Identity Document) number, your iPhone is eSIM compatible.

eSIM Compatible Android Models

On Android devices, eSIM support varies by manufacturer and model. Samsung Galaxy phones from the S20 series onward support eSIM, as do Google Pixel phones from the Pixel 3 onward. Most flagship models from OnePlus, Motorola, and Huawei released from 2020 onward also support eSIM, though coverage varies by region and model variant. To check compatibility on an Android device, go to Settings, then Connections, then SIM Manager, and look for an option to add a mobile plan or add eSIM.

Important Note About Carrier-Locked Phones

Even if your phone supports eSIM, it must not be locked to a specific carrier. Carrier-locked phones – which were commonly sold in the US on installment plans by carriers like AT&T, Verizon, and T-Mobile – can only use SIM profiles approved by that specific carrier. If your phone is still under a carrier lock, contact your carrier to request an unlock before attempting to use a third-party eSIM. Most carriers will unlock your phone after you have paid off the device in full.

What to Look for Before Buying an eSIM for International Travel

Not all eSIM plans are created equal, and the right choice depends on several factors that are specific to your travel situation. Here is what to evaluate before committing to a provider and plan.

Coverage in Your Destination Countries

The most fundamental requirement is that your eSIM provider covers all the countries on your itinerary. Most major providers publish detailed coverage maps on their websites. If you are traveling to a single country, a country-specific plan is usually the most affordable option. If you are visiting multiple countries – for example, a multi-country Europe tour covering France, Switzerland, Italy, and Greece – a regional Europe plan will provide continuous coverage across all of them without needing to purchase and switch between separate plans. For truly global travel across multiple continents, several providers now offer worldwide plans covering 150 to 200 countries.

Data Allowance vs Unlimited Plans

How much data you actually need depends entirely on how you use your phone while traveling. For basic usage – navigation with Google Maps, messaging on WhatsApp, occasional social media posting, and email – most travelers consume between 1 and 3 GB per week. If you stream music or video, make frequent video calls, or use your phone as a hotspot to connect a laptop or tablet, your consumption could easily reach 10 GB or more per week. Unlimited plans eliminate the anxiety of monitoring data usage and are strongly recommended for heavy users, families sharing a hotspot, or travelers who prefer the peace of mind of knowing they will never run out of data.

Plan Duration and Flexibility

eSIM plans are typically sold in fixed duration increments: 7 days, 15 days, 30 days, and sometimes longer. The validity period begins from your first data connection in the destination country, not from the moment of purchase or installation. If your trip is 12 days, a 15-day plan gives you a comfortable buffer. Many providers also allow you to top up with additional data or purchase an extension if your trip runs longer than planned.

Network Speed and Quality

eSIM plans work by connecting to local partner networks in each destination country. The quality of those partner networks determines your actual data speeds and reliability. The best eSIM providers partner with Tier-1 networks – the largest and most reliable carriers in each country – and support 4G LTE or 5G speeds where available. Always check the network quality claims of any eSIM provider, and look at recent user reviews on independent platforms like Trustpilot for real-world feedback on speed and reliability.

Customer Support Quality

When something goes wrong with your internet connection in a foreign country, and occasionally it will – access to responsive, helpful customer support becomes critically important. Look for providers that offer 24/7 support through live chat, email, or a dedicated app. Avoid providers whose only support option is a slow email ticketing system, as waiting 48 hours for a reply when your data is not connecting on Day 1 of a 10-day Europe trip is genuinely stressful.

Best eSIM for International Travel: Top Providers Compared

After reviewing the leading eSIM providers available to US travelers in 2026 based on coverage, pricing, data quality, user reviews, and overall reliability, here are the top four providers worth considering for your next international trip.

Quick Comparison: Top eSIM Providers for 2026

Holafly: Best eSIM for Unlimited Data and Peace of Mind

Holafly – The Unlimited Data King

Strengths: Holafly is the undisputed leader for unlimited data eSIM plans for international travel. Operating in over 160 countries, it offers truly unlimited data plans with no throttling or data caps – meaning you can stream, navigate, video call, and post to your heart’s content without ever watching a data counter tick down. Holafly has accumulated over 65,000 reviews on Trustpilot with a 4.6 out of 5-star rating – an impressive consistency score across a very large sample of real travelers. Setup is straightforward through a clean app interface, and their 24/7 customer support is highly rated for responsiveness.

Consider: Holafly is not the cheapest option for light or moderate data users. Unlimited plans start at approximately $17 and can reach $65 per month depending on destination, which may be more than a light user needs. It is a data-only eSIM – voice calls and SMS are not included, though WhatsApp calls and other internet-based communication work perfectly.

Best For: Travelers who do not want to monitor data usage. Families sharing a hotspot. Heavy users who stream music, video call, or use navigation constantly. Anyone who values peace of mind over the absolute lowest price per gigabyte.

Global Holidays USA recommends Holafly eSIM to all its travelers. Get your Holafly eSIM at globalholidays.us before your next international trip.

Airalo: Best eSIM for Wide Country Coverage and Budget Travelers

Airalo – The Widest Coverage Network

Strengths: Airalo was one of the first dedicated eSIM marketplaces and remains one of the most recognized and trusted brands in the category. It offers coverage in over 200 countries and regions – the broadest footprint of any provider in 2026 – with plans starting from as low as $4.50 for basic data packages. The Airalo app is polished, intuitive, and Apple-like in its design quality. It also offers an Airmoney loyalty program where you earn credits on every purchase, making it particularly rewarding for frequent travelers.

Consider: Airalo does not offer unlimited data plans – all plans are capped at a fixed data amount. For heavy users, the per-gigabyte pricing can add up. Some users report that top-up availability can be inconsistent in certain destinations.

Best For: Budget-conscious travelers who use data moderately. Frequent travelers who benefit from the loyalty rewards program. Travelers visiting unusual or off-the-beaten-path destinations where other providers may have limited coverage.

Saily: Best eSIM for Security-Conscious Travelers

Saily – Security-First eSIM by the Creators of NordVPN

Strengths: Saily is a relatively newer entrant to the eSIM market, but has made an immediate impact by offering something no other provider does: built-in VPN protection, an ad blocker, and web protection included as standard in every plan. This makes a meaningful difference when you are connecting to public Wi-Fi networks at airports, hotels, and cafes – all environments where your data is potentially vulnerable to interception. Saily operates in over 200 countries with plans starting from just $1.99, making it one of the most affordable options in the market. Network speeds are strong, particularly in major cities and tourist areas.

Consider: Saily’s coverage in rural areas and smaller towns can be inconsistent. It does not offer unlimited plans. Customer support, while improving, is not yet at the 24/7 standard of Holafly.

Best For: Security-conscious travelers who regularly use public Wi-Fi. Budget travelers who want the most data for the lowest price. Anyone traveling to a major city destination where Saily’s urban network coverage is strongest.

Jetpac: Best eSIM for Travel Perks and Added Benefits

Jetpac – The Rising Star with Unique Travel Perks

Strengths: Jetpac is the most exciting newer entrant to the eSIM market in 2026. Beyond solid connectivity across 150 countries with both capped and unlimited data options, Jetpac offers a standout bonus that no other eSIM provider matches: its SmartDelay service. When you register your flight with Jetpac and your flight is delayed or cancelled, you automatically receive complimentary access to airport lounges for up to five travelers. For families traveling with a tour group, the comfort of a lounge during an unexpected delay is an extraordinary perk. Jetpac has earned a 4.8 out of 5-star rating on Trustpilot.

Consider: Jetpac is newer to the market, and its coverage in some developing world destinations is not yet as comprehensive as Airalo or Holafly. The airport lounge benefit is most valuable if you register flights in advance.

Best For: Families and groups who want both connectivity and travel perks. Travelers on organized tours who value the airport lounge benefit as a safety net against delays. Anyone looking for the best combination of data quality and added travel benefits.

Best eSIM for Europe Travel from USA

Europe is the most popular international travel destination for Americans, and it is also one of the easiest places to use an eSIM thanks to the well-developed 4G and 5G networks across all major Western European countries. Whether you are visiting the Swiss Alps on the Scenic Swiss package, exploring Athens and Santorini in Greece, taking a gondola in Venice, or watching the sunset in Santorini, staying connected throughout your European journey has never been easier.

For travelers on a multi-country Europe tour – covering countries like France, Switzerland, Italy, Germany, the Netherlands, Greece, and beyond – a regional Europe eSIM plan is almost always the most practical and cost-effective choice. Rather than purchasing individual country plans and switching between them at each border, a regional plan connects automatically to partner networks in all covered European countries without any manual configuration.

Holafly’s Europe unlimited data plan is particularly popular among Global Holidays USA tour participants. For a 10-day Europe trip covering multiple countries, an unlimited data plan eliminates any concern about running out of data while navigating between cities, sharing highlights on WhatsApp with family back home, or using translation apps in non-English-speaking countries. Airalo also offers competitive Europe regional plans for lighter users, with plans starting from approximately $15 for 3GB of data valid for 30 days.

💡 Travel Tip from Global Holidays USA: Purchase and install your eSIM before you leave home in the USA. The Holafly eSIM page at globalholidays.us/holafly-esim/ makes it easy to access your eSIM plan before any Global Holidays USA tour departure. Your Tour Manager will also remind the group about connectivity options before departure.

Best eSIM for Asia Travel: Japan, South Korea, India, and Beyond

Asia presents some unique connectivity considerations that make eSIM technology particularly valuable for travelers from the USA.

Japan and South Korea

Japan and South Korea are two of the most technologically advanced countries in the world, with exceptional 5G network coverage across both urban and rural areas. However, purchasing a local SIM card in either country as a foreign visitor requires strict registration with a passport – a process that can take 30 to 60 minutes at airport counters and is conducted in Japanese or Korean. An eSIM eliminates this entirely. For Global Holidays USA travelers on the Japan and South Korea vacation package, installing a Holafly or Airalo eSIM before departure means seamless connectivity from the moment you land at Tokyo Narita Airport, without a single queue.

India

For NRI travelers from the USA visiting India, the eSIM situation has improved significantly in 2026. Both Airjio (Reliance Jio’s eSIM service) and international providers, including Airalo and Holafly now offer India coverage with competitive pricing. The key consideration for India is that network coverage, while excellent in major cities and tourist destinations, can be patchy in rural areas – so unlimited plans make sense to ensure you always have connectivity when you need it most, particularly when navigating in unfamiliar areas or using ride-hailing apps.

Southeast Asia and Beyond

For travelers visiting Thailand, Vietnam, Cambodia, Singapore, Bali, or other Southeast Asian destinations, both Airalo and Holafly offer regional Asia plans that provide continuous coverage across multiple countries. These regional plans are particularly valuable for island-hopping itineraries or multi-country Southeast Asia tours where switching between country-specific plans would be impractical.

How to Set Up and Activate Your eSIM: Step-by-Step Guide

Setting up an eSIM for the first time can seem daunting, but the process is genuinely straightforward and takes less than five minutes from start to finish. Here is the complete guide.

Step 1: Visit your chosen eSIM provider’s website or app. Select your destination country or region, choose your plan duration, and select your data allowance or unlimited plan.

Step 2: Complete the purchase using your preferred payment method. You will receive a confirmation email within minutes containing your QR code and installation instructions.

Step 3: On iPhone: Go to Settings, then Cellular, then Add eSIM, then Use QR Code. On Android: Go to Settings, then Connections, then SIM Manager, then Add Mobile Plan. Scan the QR code from your email.

Step 4: Give your new eSIM a label (e.g., “Europe Trip” or “Japan 2026”) to distinguish it from your regular US carrier profile.

Step 5: Set your data preferences: use the eSIM for data, keep your US number as the default for calls and texts. This way your US number stays active for incoming calls while the eSIM handles internet data.

Step 6: Upon arrival at your destination, turn off airplane mode. Your phone will automatically connect to a local partner network. You are online. Enjoy your trip.

Common eSIM Problems and How to Fix Them

eSIMs work seamlessly the vast majority of the time. When issues do occur, they are almost always minor and easily resolved. Here are the most common problems and their solutions.

eSIM Not Connecting After Landing

If your eSIM does not connect automatically when you land, the first and most effective fix is a simple phone restart. After restarting, go to Settings and ensure that Data Roaming is turned on for the eSIM profile. If the issue persists, check that you have selected the correct eSIM as your data line in the cellular settings. In very rare cases, you may need to manually select the network – go to Settings, Cellular, Network Selection, turn off Automatic, and select an available local network from the list.

eSIM Showing No Service

This usually indicates that you are in an area with limited partner network coverage, or that your eSIM’s activation window has expired (some providers require you to connect within a certain number of days after installation). Check your provider’s coverage map for your specific location. If you are in a covered area and still see no service, contact the provider’s customer support via their app or website.

Data Running Out Faster Than Expected

Background app refresh, automatic updates, and cloud sync can consume significant data without you realizing it. Before your trip, go to Settings and disable Background App Refresh for apps that do not need it. Set your iCloud or Google Photos sync to Wi-Fi only. Also disable automatic app updates via cellular data. These simple steps can reduce your background data consumption by 50% or more, making your data plan last significantly longer.

eSIM Installation Fails

If the QR code scan fails, ensure you are in a Wi-Fi-connected area during installation (eSIM profiles are downloaded over the internet). Check that your phone is not in airplane mode. If the issue continues, most providers allow you to download the eSIM profile directly through their app as an alternative to QR code scanning.

How Much Does an eSIM Cost for International Travel in 2026?

eSIM pricing has become significantly more competitive in 2026 as the market has matured and more providers have entered the space. The cost of an eSIM depends on three primary factors: the destination, the duration of the plan, and the amount of data included.

For a 7-day Europe plan with 5GB of data, prices from reputable providers range from approximately $15 to $25 per person. A 10-day Europe unlimited data plan from Holafly costs approximately $35 to $45, depending on the specific countries covered. For a 30-day Asia regional plan with 10GB of data from Airalo, prices start at approximately $20. Saily offers particularly competitive pricing, with some short-duration plans starting from just $1.99 for 1GB in specific countries.

To put these costs in perspective, consider the alternative. International roaming from a major US carrier like AT&T or Verizon typically costs $10 per day. A 10-day Europe trip on a roaming plan would cost $100 per person – significantly more than an unlimited eSIM plan that provides better coverage and faster speeds. For a family of four on a 10-day Europe tour, the savings from using eSIM over carrier roaming amounts to approximately $260 to $360 in data costs alone.

eSIM Tips for Indian Families and NRI Travelers from USA

For the large community of Indian-American and NRI travelers who travel between the USA and various international destinations each year – whether to Europe on a Global Holidays USA tour, to India to visit family, or to other international destinations – eSIM technology addresses several specific pain points that are particularly relevant to this traveler demographic.

Many NRI travelers maintain two phone numbers: their US number for daily life and business, and an Indian number for family communications. A dual-SIM approach with an eSIM for data is ideal for this situation. Keep your physical Indian SIM in the SIM card slot for calls and texts on your Indian number, activate a Holafly or Airalo eSIM for data, and keep your US eSIM profile dormant on the device. When you return to the USA, simply switch your active data plan back to the US eSIM and deactivate the travel plan.

For families traveling on Global Holidays USA Europe tours, a single unlimited data eSIM with hotspot capability means that one family member’s phone can serve as a Wi-Fi hotspot for the entire family’s devices – tablets, laptops, and additional phones included. This single-plan-for-the-whole-family approach is significantly more economical than purchasing individual eSIM plans for each device.

WhatsApp is the primary communication tool for Indian families worldwide, and the good news is that WhatsApp works perfectly on eSIM data plans. Even on a data-only eSIM without voice call capability, WhatsApp calls, video calls, and messaging function exactly as they do at home – allowing NRI travelers to stay in close contact with family in India and across the diaspora throughout their international journey.

Jetpac is the best choice for travelers who want connectivity plus travel perks like airport lounge access during delays. Global Holidays USA recommends Holafly for its tour participants due to its unlimited plans, strong coverage in European and Asian destinations, and excellent customer support.

How does an eSIM work for international travel?

An eSIM works by storing a digital carrier profile on a chip embedded permanently in your phone’s hardware. When you purchase an eSIM plan from a provider like Holafly or Airalo, you receive a QR code by email. Scanning this QR code installs the carrier profile on your phone, which then connects automatically to local partner networks when you arrive at your destination. You keep your US number active for calls while the eSIM handles data. The whole setup process takes less than five minutes and can be completed from home before you travel.

How do I use an eSIM for international travel from the USA?

Using an eSIM for international travel from the USA is a four-step process. First, confirm that your phone is eSIM compatible and carrier-unlocked. Second, purchase your eSIM plan from a reputable provider’s website or app before departure, selecting your destination and data requirements. Third, install the eSIM on your phone by scanning the QR code from the provider’s email. Fourth, arrive at your destination, turn off airplane mode, and your eSIM connects automatically. You are online within seconds of landing. Visit globalholidays.us/holafly-esim/ for easy access to Holafly eSIM plans recommended by Global Holidays USA.

Will my phone work with an international eSIM?

Most smartphones purchased in the last three to four years are eSIM compatible. On iPhone, check Settings, then General, then About – if you see an EID number, your phone supports eSIM. On Android, check Settings, then Connections, then SIM Manager for an Add eSIM option. Your phone must also be carrier-unlocked to use a third-party eSIM provider. iPhones purchased in the USA since the iPhone 14 are completely unlocked and fully eSIM-only devices, making them ideal for international eSIM use.

How much does an eSIM cost for a trip to Europe from the USA?

An eSIM for a European trip from the USA typically costs between $15 and $45, depending on the duration, data allowance, and provider. A 7-day Europe plan with 5GB of data from Airalo costs approximately $15 to $20. A 10-day unlimited data Europe plan from Holafly costs approximately $35 to $45. This compares very favorably with international roaming from a US carrier, which typically costs $100 or more for the same period, with slower speeds and less reliable coverage.

Can I keep my US phone number active when using an international eSIM?

Yes. This is one of the most significant advantages of eSIM technology for international travel. Your phone can run two profiles simultaneously: your regular US carrier profile (which keeps your US phone number active for incoming calls and texts) and your eSIM data plan (which handles internet connectivity abroad). WhatsApp, FaceTime, and other internet-based communication apps work perfectly on the eSIM data connection, while your US number remains available for SMS authentication and incoming calls.

Is Holafly eSIM good for international travel?

Yes, Holafly is one of the highest-rated eSIM providers for international travel. It operates in over 160 countries, offers truly unlimited data plans without throttling or data caps, and has earned a 4.6 out of 5-star rating from over 65,000 reviews on Trustpilot. Its plans are easy to purchase and install, its 24/7 customer support is responsive, and its unlimited offering provides genuine peace of mind for travelers who do not want to monitor data consumption. Global Holidays USA recommends Holafly to all its international tour participants. Get your Holafly eSIM here.

What is the difference between an eSIM and a physical SIM card?

A physical SIM card is a small, removable plastic chip that you insert into your phone to connect to a carrier network. An eSIM is a permanent chip built into your phone’s hardware that can be programmed with different carrier profiles via QR code or app download, without any physical card being used. eSIMs cannot be lost, stolen, or accidentally removed. They can store multiple carrier profiles simultaneously, allow instant switching between providers, and can be purchased and activated entirely online before or during travel – making them significantly more convenient than physical SIM cards for international travel.

Do I need Wi-Fi to install an eSIM?

Yes. When you scan the QR code to install an eSIM, your phone downloads the carrier profile from the provider’s servers, which requires an internet connection. For this reason, it is strongly recommended to install your eSIM at home and connect to your regular Wi-Fi before you leave for the airport. If you need to install it at the airport, use the airport Wi-Fi. Never attempt to install your eSIM in a location where you have no internet access.

Can I use an eSIM as a hotspot to share internet with my family?

Yes, most eSIM plans support mobile hotspot (tethering) functionality, which allows you to share your eSIM’s data connection with other devices, including tablets, laptops, and additional phones. This makes it very practical for families traveling together to share a single eSIM plan among multiple devices, reducing the overall cost of connectivity for the whole group. Check with your specific provider that hotspot is included in your plan before purchasing, as a small number of providers restrict tethering on certain plans.

Conclusion

International travel is one of life’s most enriching and transformative experiences. It connects you with history, culture, beauty, and perspectives that no amount of reading or watching can fully replicate. And in 2026, staying connected during that journey – for navigation, communication, sharing, and safety – is not a luxury but a practical necessity that shapes the quality of every day you spend abroad.
