Plans are mostly data-only, which suits travelers who already use WhatsApp, Telegram, or other apps for calls and messaging.

Coverage includes popular plans for Europe, Southeast Asia, the United States, Australia, New Zealand, and Japan.

Data volumes generally range from 5 to 50 GB, suited for short to medium stays rather than ultra-intensive use.

Activation is quick thanks to the QR code sent within minutes after purchase, convenient for last-minute preparation.

Description

AirDataLink is an eSIM provider dedicated to travelers who want to stay connected without roaming fees or physical SIM cards. The plans are mainly data-only offers, available for individual countries like Japan or the United States, as well as for regions such as Europe or Oceania, generally with volumes between 5 and 50 GB for 7 to 30 days. Purchases are made online, the QR code is sent by e-mail, and activation takes just a few minutes on a compatible eSIM smartphone. AirDataLink is mainly suited for leisure and business travelers who prioritize simplicity and a reliable connection for browsing, social networks, and work tools on the go.

How it works

Before purchasing, make sure your smartphone is unlocked and eSIM-compatible by checking for an EID in the device information.

Go to the AirDataLink website, choose your destination (country or region), select the data volume and desired duration, then complete the payment.

After purchase, AirDataLink sends you an e-mail containing the eSIM QR code and installation instructions, usually within minutes.

Open cellular settings on your smartphone, choose the option to add a mobile plan, and scan the QR code provided by AirDataLink.

Assign the AirDataLink eSIM for data use, verify or enter the APN if necessary, and keep the physical SIM for calls/SMS if you wish.

Once in the covered country, activate the AirDataLink profile in settings and enable data roaming to start the connection.

Regularly check data usage in your phone's settings or through third-party tools to avoid exhausting your plan too quickly.

⚠️ If it fails

✅ Check that your phone is eSIM compatible, that you have a stable Wi-Fi connection, and that the QR code is not blurry. If the problem persists, restart the device and contact AirDataLink support.

✅ Make sure the AirDataLink profile is selected for mobile data, roaming is enabled, and the APN recommended by AirDataLink is correctly entered. Try toggling airplane mode or restarting.

✅ Move if possible to an area with better coverage, disable VPN and heavy downloads, then test again. Keep in mind rural areas may have more limited coverage.

✅ Reduce video streaming, disable automatic updates and background cloud sync, and monitor the most data-hungry apps in your smartphone settings.
