Picture this: you’ve just landed at Tokyo Narita Airport after a 14-hour flight. You’re exhausted, you need to find your hotel, and your phone shows zero bars of service. You spend the next 40 minutes hunting for a SIM card kiosk, filling out a paper form in a language you don’t speak, only to discover the kiosk only accepts cash in yen you haven’t exchanged yet.
This is the experience that Holafly eSIM was built to eliminate entirely.
If you’re a first-time user wondering how to use Holafly eSIM, how to activate it, what it actually costs, and whether it works in the USA, Europe, Japan, or China, you’ve found the right guide. We’ve broken down every step from purchase to full internet connection so you can travel smarter, not harder.
What is Holafly eSIM and Why Travelers Love It
Holafly is a Spanish travel technology company that sells digital SIM cards, known as eSIMs, for travelers visiting over 220 destinations worldwide. Unlike a traditional SIM card that you physically insert into your phone, an eSIM (embedded SIM) is a digital profile that you download directly onto your device. There’s no plastic card, no trip to a phone shop, and no paperwork.
What sets Holafly apart from competitors is its commitment to unlimited data plans. Rather than selling you 3 GB or 10 GB and leaving you anxiously watching a data counter, Holafly charges you based on the number of days you need coverage. You pay for time, not gigabytes. This model has proven enormously popular with digital nomads, international business travelers, families on vacation, and anyone who uses navigation, streaming, or video calls while abroad.
Since its founding, Holafly has sold over 10 million travel eSIMs worldwide, building a reputation for reliable connectivity and strong customer support available 24 hours a day, 7 days a week.
How Does Holafly eSIM Work? Simple Truth Behind the Technology
Understanding how Holafly eSIM works helps you use it with confidence. Here is the straightforward explanation.
When you buy a Holafly eSIM, you receive a QR code and an activation code by email. This QR code contains a digital SIM profile, essentially all the information a carrier needs to connect your phone to their network. When you scan that QR code through your phone’s settings, your device downloads and installs the eSIM profile. Your phone now has two SIMs running simultaneously: your original physical SIM (which handles calls and texts from your home number) and the Holafly eSIM (which handles mobile data while abroad).
The process has two distinct phases: installation and activation. Installation happens before your trip, at home, on a stable Wi-Fi connection. Activation happens when you arrive at your destination and turn on data roaming for the Holafly line. Your data plan days only start counting from the moment you activate it at your destination, which means you won’t waste a single day sitting on a plane.
Holafly connects your phone to major local carrier networks in each country. In Japan, for example, it routes through networks like KDDI and SoftBank. In Europe, it connects seamlessly to dominant local carriers across more than 40 countries. This partnership with established local networks is why the service feels reliable rather than patchy.
Is Your Device Compatible with Holafly eSIM?
Before purchasing, you need to confirm two things: your phone supports eSIM technology, and your phone is carrier-unlocked.
On the iPhone side, eSIM capability was introduced with the iPhone XR, iPhone XS, and iPhone XS Max. Any iPhone released after those models, including the iPhone 11, 12, 13, 14, and 15 series, supports eSIM. The iPhone 14 and later models released in the USA are actually eSIM-only and have no physical SIM tray at all, making them perfectly suited for Holafly.
On Android, eSIM support varies significantly by model and region. Samsung Galaxy S20 and newer flagship models generally support eSIM, as do Google Pixel 3 and later phones, and many recent Motorola, Oppo, and Huawei models. The quickest way to check is to go to Settings and look for a “SIM Manager” or “Add eSIM” option. If you find it, your phone supports eSIM technology.
The second requirement is equally important: your device must be carrier-unlocked. A locked phone is restricted to work only with your home carrier’s SIM cards. If you bought your phone outright or have completed your contract, it is likely already unlocked. If you’re unsure, contact your carrier or check your phone’s settings. A locked device will not be able to use any third-party eSIM, including Holafly.
Also worth noting: Holafly is a data-only service. You can make calls and send texts using internet-based apps like WhatsApp, FaceTime, or Skype, but Holafly eSIM does not support traditional voice calls or SMS to regular phone numbers. Your home SIM remains active for those purposes.

How to Buy a Holafly eSIM: A Step-by-Step Purchase Guide
Buying your Holafly eSIM takes less than five minutes. Here’s how the process works.
Step 1: Visit the Holafly website or download the Holafly app.
You can purchase directly at esim.holafly.com or through their mobile app available on both iOS and Android.
Step 2: Search for your destination.
Type in the country or region you’re traveling to. Holafly will show you all available plans for that destination. If you’re visiting multiple countries, check whether a regional plan covers your itinerary; the Europe regional plan, for instance, covers over 40 countries under a single eSIM.
Step 3: Select your plan duration.
Plans range from 1 day to 90 days, depending on the destination. Longer plans offer better daily rates. A 30-day plan costs significantly less per day than several shorter plans purchased separately.
Step 4: Complete the checkout.
Enter your email address, choose your payment method (credit card, PayPal, and other options are accepted), and apply any Holafly discount code you may have. You’ll receive your QR code and setup instructions at the email address you provide within minutes of purchase.
Step 5: Check your email.
Look for an email from Holafly with your QR code attached. Save this email or screenshot the QR code, because you’ll need it accessible on a second screen when installing on your phone.

When Should You Install and Activate Your Holafly eSIM?
This is one of the most common questions first-time users ask, and the answer follows a simple rule: install before you leave home, activate when you land.
Holafly recommends installing your eSIM at least one day before your trip. Installation requires a stable Wi-Fi connection, and airport Wi-Fi is notoriously unreliable. Installing at home, where your connection is strong and consistent, ensures a smooth process. The installation itself typically takes between two and five minutes.
Your data plan does not start counting down during installation. The days only begin when you actually activate the eSIM at your destination by turning on data roaming. This means you can install the eSIM a week before your trip and it will just sit quietly on your device, ready to go the moment you arrive.
Once you land at your destination, the activation process takes about 30 seconds: you simply navigate to your phone’s cellular settings, select the Holafly eSIM line, ensure it is turned on, and enable data roaming. From that point forward, your plan is live and your days start counting.
One practical tip: if your phone automatically activates the eSIM before you travel, simply keep data roaming turned off on the Holafly line until you reach your destination. Your usage days will only start counting once the eSIM actually connects to a local network.
How to Install Holafly eSIM on iPhone (Step-by-Step)
Installing a Holafly eSIM on an iPhone is the most straightforward of all device types. Follow these steps carefully, and remember you’ll need to have your QR code visible on a second screen (a laptop, tablet, or printed copy) since you can’t scan a QR code on the same phone you’re installing it on.
Method 1: QR Code Installation (Most Common)
Open the Settings app on your iPhone and tap on “Cellular” or “Mobile Data” depending on your iOS version. Tap “Add eSIM” or “Add Data Plan.” Select “Use QR Code” and point your camera at the Holafly QR code on your other screen. Your iPhone will detect the code and begin the installation process automatically. Tap “Continue” when the Activate eSIM screen appears (note: tapping Continue at this stage does not yet activate the plan; it simply moves you through the setup wizard). Give your new Holafly line a name you’ll recognize, such as “Holafly Japan” or “Holafly Europe.” When prompted about your default line, select your original SIM as the default for calls and messages, and set the Holafly eSIM as your default for cellular data. Tap “Done” when setup is complete.
Method 2: Manual Installation
If you’re unable to scan the QR code, you can enter your details manually. Navigate to Settings, then Cellular or Mobile Data, then Add eSIM. Select “Use QR Code” and then choose “Enter Details Manually.” Copy and paste the SM-DP+ Address and Activation Code from your Holafly email into the corresponding fields. Tap Next and follow the same on-screen setup steps as described above.
Method 3: Via the Holafly App (iOS 17.4 and Later)
If your iPhone runs iOS 17.4 or later, you can install the eSIM directly through the Holafly app. Download the app, log in with the email associated with your purchase, go to “My eSIMs,” select your plan, and tap “Install and Activate.” The app guides you through everything automatically.
One critical reminder: the QR code can only be scanned once. Do not delete the eSIM from your device after installation, as reinstallation requires contacting Holafly support.
How to Install Holafly eSIM on Android (Samsung, Google Pixel & More)
Android installation varies slightly by manufacturer, but the core process is the same across devices.
For Samsung Galaxy Devices:
Open Settings and tap “Connections.” Tap “SIM Card Manager” and then select “Add eSIM.” Choose “Scan QR Code” and point your camera at the Holafly QR code on a second screen. If you prefer, select “Enter Activation Code” and paste the code from your email. Follow the on-screen prompts to complete installation, including assigning a name to your new line such as “Holafly Spain.” Alternatively, on Samsung devices running One UI 5 or later, you can use the Holafly app: download the app, log in, go to My eSIMs, select your plan, and tap “Install and Activate” followed by “Automatic.”
For Google Pixel Devices:
Open Settings and go to “Network & Internet.” Tap the “+” icon next to your existing SIM. Scroll to the bottom and tap “Download a SIM instead?” A message will ask if you want to use two SIMs; tap “Yes.” Point your camera at the QR code to scan it. Once installed, you can rename the eSIM from your network settings.
For Motorola Devices:
Go to Settings and tap “Network & Internet,” then “Mobile Network.” Tap “Download New SIM” and select “Set up an eSIM.” Follow the prompts to scan your QR code or enter the activation code manually.
For all Android devices, an important note about the manual code: unlike iPhone, Android uses a single combined activation code (sometimes called an LPA code) that includes a colon (:) separator. Make sure to copy the entire code exactly as provided in your email, including all characters and the colon, without adding any spaces.
How to Activate Your Holafly eSIM at Your Destination
Installation adds the eSIM to your device. Activation is what actually connects it to the local network and starts your data plan. These are two separate steps, and activating correctly is where many first-time users get confused.
Activating on iPhone :
Open Settings and tap “Cellular” or “Mobile Data.” Find your Holafly line (it will show the name you gave it during installation). Tap on it and make sure “Turn On This Line” is enabled. Scroll down and turn on “Data Roaming.” Go back to the main Cellular screen, tap “Cellular Data,” and select your Holafly eSIM as the active data line. Also ensure “Allow Cellular Data Switching” is turned off to prevent your phone from accidentally using your home carrier line for data. Make sure at least one signal bar appears for the Holafly line, confirming you’ve connected to a local network.
Activating on Samsung Android :
Open Settings, go to “Connections,” and tap “SIM Manager.” Turn off your personal SIM to avoid unexpected charges from your home carrier. Turn on your Holafly eSIM. Tap “Mobile Data” and select the Holafly line. Go back to “Connections,” tap “Mobile Networks,” and enable “Data Roaming.” Wait a moment for your phone to register with the local network, then test by opening a browser or app.
The Golden Rule: If your data isn’t working immediately after activation, wait two to three minutes. The phone needs time to register with the local carrier’s towers. If it still doesn’t connect, try manually selecting a network by going to your mobile network settings, turning off “Automatic Network Selection,” and choosing a carrier from the list that appears. Select the one with the strongest signal and test your connection again.
Holafly eSIM for Popular Destinations: USA, Europe, Japan, China & More
Holafly eSIM USA
The Holafly eSIM for the United States works across the country using major domestic networks, offering strong coverage in cities and suburban areas. For travelers visiting landmarks like New York City, Los Angeles, Chicago, or Miami, the connection is consistently reliable. Rural coverage may show some variation, as is true of any mobile provider in areas with lower tower density. The North America regional plan also covers the USA, Canada, and Mexico under a single eSIM, making it ideal for road trips or multi-country visits.
Holafly eSIM Europe
The Europe regional eSIM is widely considered Holafly’s best value offering. It covers over 40 European countries including France, Germany, Spain, Italy, the United Kingdom, Greece, Portugal, Switzerland, Austria, the Netherlands, and many more. Travelers can cross borders without touching their phone settings; the eSIM automatically connects to local networks in each country. Major cities across Europe deliver fast 4G and 5G speeds. Rural and mountainous areas, like parts of rural Tuscany or remote mountain passes, may see reduced speeds, but this reflects local infrastructure rather than a flaw specific to Holafly. The Europe eSIM is available in plans from 1 to 90 days, with the longer plans offering some of the lowest daily rates in the industry.
Holafly eSIM Japan
Japan is one of Holafly’s strongest performing destinations. The eSIM connects through networks including KDDI and SoftBank, which together provide some of the most advanced mobile infrastructure in the world. Travelers to Tokyo, Osaka, Kyoto, and other urban centers consistently report fast 4G and 5G speeds. Even on day trips to areas like Hakone or rural onsen towns, connectivity remains functional for maps and messaging, though HD streaming in remote areas may not always be stable due to tower distribution rather than the eSIM itself. For anyone planning a trip to Japan, the Holafly eSIM is a highly recommended choice.
Holafly eSIM China
China deserves a special mention because of its unique internet environment. The Holafly China eSIM works through China Mobile’s network and does provide data connectivity. However, China’s Great Firewall blocks most Western apps and websites by default, meaning services like Google, Instagram, WhatsApp, and YouTube will not work without a VPN. If you plan to use these services in China, download and configure a reputable VPN before you leave your home country, since VPN websites may also be blocked inside China. The Holafly China eSIM is a solid choice for the 240-hour transit visa scenario or a short stay, but understanding the VPN requirement is essential for anyone expecting access to their usual apps.
Holafly eSIM for Other Regions
Holafly also covers Southeast Asia (Thailand, Vietnam, South Korea, Singapore, Malaysia, Indonesia, and more), Latin America (Brazil, Argentina, Colombia, Peru, Chile, and beyond), the Middle East, and parts of Africa. Regional plans bundle multiple countries together so you don’t need to purchase a new eSIM every time you cross a border.
Holafly eSIM Plans and Pricing: What You Actually Pay
Holafly’s pricing structure is simple and transparent: you pay per day, and the daily rate decreases as you buy more days. All standard plans include unlimited data, meaning there is no hard data cap, though network providers may apply speed throttling after heavy daily usage under their fair usage policies.
Short-term plans, such as a 1-day plan, start at around $6 to $7, depending on the destination. Mid-length plans of 7 to 14 days offer better value, while 30-day plans bring the daily cost down significantly, sometimes as low as $2.37 per day for popular destinations like Europe. Some destinations offer plans up to 90 days, which pushes the daily rate even lower.
Regional plans follow the same pricing logic but add the convenience of multi-country coverage. The Europe regional plan, the Asia regional plan, and the North America regional plan are the most popular.
For frequent travelers and digital nomads, Holafly launched subscription-based “Holafly Plans” that offer rolling monthly coverage across 160 to 170 countries. These plans come in two tiers: one offering 25 GB per month and one offering unlimited data, with the latter costing around $65 per month. Both include a European phone number for receiving SMS verification codes. You can cancel at any time.
Hotspot tethering is included with most plans, though standard eSIM plans typically have a daily tethering cap (often 500 MB to 1 GB). The monthly subscription plans include more generous or unlimited tethering.
Holafly eSIM Review: Real User Experience Pros and Cons
Based on aggregated real user experiences and independent testing across multiple destinations, here is an honest assessment of Holafly eSIM.
What Works Well
The setup process is genuinely simple, especially on iPhone. Most users describe it as taking under five minutes from QR code to working connection. The unlimited data model removes the anxiety of tracking gigabytes and is especially valuable for travelers who rely on navigation, video calls, and social media throughout the day. Coverage in Europe, Japan, and North America is consistently praised. Customer support is available 24/7 through live chat and WhatsApp, and users report being connected to a real human quickly when needed. The Holafly app allows you to monitor your plan status, check usage, and manage your eSIM in one place.
Where It Has Limitations
Holafly is not the cheapest option on the market, particularly for short trips. If you’re visiting a country for just two or three days and plan light data usage, a capped plan from a competing provider may cost less. Hotspot tethering limits can frustrate remote workers who need to connect laptops to their phone’s data. Data speeds can be throttled after heavy daily usage, so calling the plan “truly unlimited” requires a nuanced understanding of fair-use policies. Holafly is also unavailable as a service in certain markets, including India and Turkey, due to local regulatory restrictions.
The Bottom Line
Holafly is a strong, reliable choice for travelers who prioritize convenience, want unlimited data, and are visiting popular international destinations for more than a few days. It earns its reputation as one of the best travel eSIMs available, even if it asks a slight premium for that reliability.
Holafly eSIM Troubleshooting: What to Do If It’s Not Working
Even with a perfectly installed eSIM, you might occasionally encounter issues. Here are the most common problems and their solutions.
Problem: No Signal After Activation
The most common reason data doesn’t work after activation is that data roaming is not enabled. Go back to your phone’s cellular settings, find the Holafly line, and confirm data roaming is turned on. This is the fix for the vast majority of activation issues.
Problem: Shows Connected But No Internet
If your phone shows signal bars for the Holafly line but you cannot load any websites or apps, try manually selecting a network. Turn off automatic network selection in your mobile network settings, wait for available carriers to load, and try each one listed until you find one that works.
Problem: Wrong Destination
Your Holafly eSIM is programmed for a specific destination or region. If you arrive somewhere other than where your plan is valid, the eSIM will not connect. Always confirm that the plan you purchased matches your travel destination before installing.
Problem: Accidentally Deleted the eSIM
Never delete the eSIM from your device to try to fix a connection issue. Deleting the profile can permanently invalidate your plan. If you deleted it accidentally, contact Holafly’s 24/7 support chat immediately. They can sometimes assist with reinstallation depending on the circumstances.
Problem: Dual SIM Conflict
If you have both your home SIM and the Holafly eSIM active, your phone may default to using the wrong line for data. Go to your cellular data settings and manually select the Holafly eSIM as the data line. Also, turn off “Allow Cellular Data Switching” (iPhone) or equivalent settings on Android to prevent your phone from reverting to your home carrier.
How to Save Money: Holafly eSIM Discount Codes and Tips
Holafly eSIM is priced at a premium compared to some alternatives, but there are legitimate ways to reduce the cost.
Use a Holafly Discount Code: Holafly regularly works with travel bloggers and partners who provide discount codes offering 5% to 10% off your purchase. Searching for a current “Holafly eSIM discount code” before checkout is always worth doing. These codes are entered at the checkout page and apply to any destination and plan length.
Choose Longer Plans: The single most effective way to reduce your daily cost is to buy the longest plan that covers your trip. If you’re traveling for 10 days, compare the cost of a 7-day plus a 3-day plan separately versus a single 14-day plan. The 14-day plan will almost always have a lower daily rate.
Consider Regional Plans: If you’re visiting two or more countries in a region, a regional eSIM is almost always more economical than purchasing separate eSIMs for each country. The Europe regional plan is a classic example: one purchase covers over 40 countries, and the daily rate is among the best Holafly offers.
Earn HolaCoins: Holafly’s loyalty rewards program, the Travel Club, gives you HolaCoins for every purchase. These coins accumulate and can be redeemed for discounts on future eSIMs. If you travel regularly, registering an account and collecting coins adds up over time.
Subscribe for Long-Term Travel: If you’re abroad for more than 30 days, the Holafly monthly subscription plan at around $65 per month can be more economical than purchasing back-to-back destination eSIMs, especially when traveling across multiple countries.
Conclusion
After examining every aspect of how Holafly eSIM works, from purchase through activation to real-world performance, the answer for most international travelers is a clear yes.
The convenience of buying your connectivity before you board, skipping airport SIM kiosks, and arriving at your destination with instant internet access is genuinely valuable. The unlimited data model eliminates the stress of rationing gigabytes. The wide destination coverage, strong performance in key markets such as the USA, Europe, and Japan, and responsive 24/7 customer support make Holafly a trustworthy choice.
It isn’t the cheapest option for every situation. If you’re taking a very short trip, use minimal data, and are comfortable seeking out a local SIM at your destination, there are less expensive alternatives. But for the traveler who values simplicity, reliability, and peace of mind, Holafly eSIM is among the best investments you can make before international travel.
