To check if your phone is eSIM-compatible, the quickest method is to dial *#06#—if you see an EID number, your device has an eSIM chip and can support eSIM plans.

You’ll also need to make sure your
phone is unlocked, as eSIMs won’t work on carrier-locked devices.

Most newer models from Apple, Samsung, Google, and Huawei support eSIM, but not all
do. You can also go to Settings > Mobile Network / SIM Manager and
look for an option like “Add eSIM” or “Download eSIM”.

No, you don’t need any app to use eFlySim.

Once you buy a plan online, we’ll email you a QR code that installs directly through your phone’s settings.

It’s all built-in—no downloads, no contracts, no account setup. Just scan the code, activate your eSIM, and you’re ready to go.

1. Connect to strong Wi-Fi or mobile internet
   A stable connection is needed to download the eSIM profile.
2. Open your Camera app
   Point it at the QR code we sent.
3. Tap the pop-up
   It should say “Add Plan to Phone,” “Add Cellular Plan,” or something similar.
4. Follow the prompts
   Accept the default options unless you have a reason to change them.
5. Turn on Data Roaming
   Go to Settings → Cellular Data → [Your new eSIM plan] and switch Data Roaming to ON.

Your plan may be labeled “Secondary” or “Personal”—that’s normal.

Manual setup available
If the QR code doesn’t scan, you can enter the SM-DP+ and activation code manually.

Once your eSIM is activated, your phone will search for a signal automatically. You’ll usually see 4G, LTE, or 5G within seconds—meaning you’re online.

If it takes longer than 15 minutes, check our troubleshooting guide.

Quick checklist to get online after activating your eSIM:

1. Make sure your eSIM is active and set as the mobile data line
2. Turn on Data Roaming
3. Check for signal bars

• If it says No Signal, restart your phone

1. Have signal but no data?

• Turn the eSIM off and back on
• Manually select a network
• Check APN settings (especially on Android)
  → You’ll find APN and network details in your sharable link

First-time activation can take up to 15 minutes.

APN settings help your phone connect to mobile data. If they’re missing or incorrect, you’ll see signal bars but no internet.

This comes up most often on Android, especially when roaming.

iPhones usually set APNs automatically, but in Japan, Turkey, and Morocco, you may need to enter them manually.

You’ll find the APN for your destination in your email, and step-by-step instructions are available in our manual setup guide

If setup isn’t working, here’s what to check:

• Make sure your phone is unlocked and supports eSIM
• Connect to Wi-Fi or mobile data during installation
• Use your phone’s built-in camera app—not a third-party QR scanner
• Make sure your QR code hasn’t already been scanned by another device
• Each eSIM is for one phone only—it won’t work on multiple devices

You may have used up all your data. Sometimes data usage is not real-time measurement.
For precise data usage, you can go to system Setting->Cellular to check your data consumption.

DO NOT delete your eSIM when you haven’t used up your data.

1. Try to reinstall from the original QR code.
2. If you accidentally delete your eSIM after your activation, you may have to purchase a new eSIM.

Your eSIM won’t be available to transfer if you have already activated. You could still enjoy eSIM if you haven’t activated it before changing the device.

We don’t offer automatic top-ups or app-based refills yet. But if you need more data, here’s how to do it:

• Buy another plan for the same country while your current eSIM is still active
• Send us a quick message in the chat—we’ll link the new plan to your existing eSIM
• No need to reinstall or scan anything again

It’s best to top up before your data runs out to avoid any interruption. This manual method keeps things simple and flexible.

Your eSIM should connect automatically after landing, as long as it’s installed and activated before your flight. Just make sure mobile data and data roaming are on.

If it doesn’t connect right away, don’t worry—check the troubleshooting guide included in your QR code email. That usually solves it quickly.
