Why is your NPN Travel eSIM not working?

Your NPN travel eSIM not working might be due to setup errors, device compatibility, or network configuration. Below are the most common reasons, and they’re usually easy to check and fix:

Your device doesn’t support eSIM: Not all smartphones are eSIM-compatible. NPN eSIMs only work on supported models like iPhone XR or newer, Google Pixel 4+, or Samsung Galaxy S20 and above.
The eSIM wasn’t installed or activated before your trip: You must activate your eSIM via QR code while connected to Wi-Fi before travelling. If activation is incomplete, it won’t work abroad.
Mobile data or data roaming is turned off: Double-check your phone settings to make sure both Mobile Data and Data Roaming are enabled; these are essential for using an eSIM overseas.
The activation QR code is invalid or already used: NPN QR codes are typically single-use. If reused or expired, you’ll need a new QR code issued.
Local network coverage is weak or unavailable: If you’re in a remote area or experience poor coverage, try switching to another network manually or rebooting your device.
Incorrect or outdated APN settings: If your phone doesn’t automatically configure the APN, you’ll need to enter it manually. Missing or wrong APN details will prevent data usage.
Your data allowance is used up: Once your plan’s data is exhausted, your eSIM won’t connect. NPN eSIMs are prepaid and typically don’t support top-ups mid-trip.

How to fix NPN Travel eSIM issues

Troubleshooting your NPN eSIM is often straightforward. Below are practical fixes for the most common setup and connectivity issues, with separate tips for iPhone and Android where needed.

Check if your device supports eSIMs

First, confirm that your device is eSIM-compatible and is unlocked from any carrier restrictions.

iPhone: Models from XR and newer support eSIM.
Android: Supported on recent Samsung (S20+), Google Pixel (Pixel 4+), Huawei P40, and other flagship models.

If unsure, check your device settings:

iPhone: Go to Settings → Mobile Data (or Cellular) → Add eSIM
Android: Go to Settings → Connections → SIM card manager

If the “Add eSIM” options are there, it means your phone is eSIM-compatible.

For iPhone users, simply follow these steps to check if your phone supports eSIM.

Reinstall the eSIM profile

Sometimes the QR code installation fails.

iPhone: Go to Settings → Mobile Data → Remove Plan, then re-scan the QR code from NPN using Add eSIM
Android: Go to Settings → Connections → SIM Manager, remove the existing eSIM, and re-add it using the QR code.

Ensure you’re connected to stable Wi-Fi during your eSIM setup. Keep in mind that many QR codes are one-time use only, so you may need to contact your provider and request a new code if the old one is no longer working.

Restart your phone after installation

A restart helps finalise the eSIM configuration and allows it to connect to the local network.

Turn on data roaming

Your eSIM won’t connect without data roaming enabled.

iPhone: Settings → Mobile Data → Data Roaming → ON
Android: Settings → Mobile Network → Mobile Data + Data Roaming → ON

If you are an Android user, follow these steps to easily turn on your mobile data and data roaming to stay connected.

Enable and disable Airplane Mode

Toggle Airplane Mode ON, wait 10 seconds, then turn it off. This resets your mobile signal and forces the phone to reconnect to the network.

Manually select a local network

If auto-connection fails, try to select a local network manually on your phone. Here is how to do it:

iPhone: Settings → Mobile Data → Network Selection → Turn off Automatic and choose the recommended carrier manually.
Android: Settings → Connections → Mobile Networks → Network Operators → Search manually and select the available network.

Update or reset your APN settings

Incorrect APN details block data access even when you have a signal.

Check NPN’s official APN settings (often listed on their activation email or website).
iPhone: Settings → Mobile Data → Mobile Data Network
Android: Settings → Mobile Networks → Access Point Names

Ensure the APN is correct, or reset it to default.

Reset network settings

If all else fails, a full reset can clear old configurations:

iPhone: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings
Android: Settings → System → Reset Options → Reset Wi-Fi, mobile & Bluetooth

If your eSIM still doesn’t work after trying all fixes, you can contact NPN Travel via the support email listed on their official website.

Alternatively, consider switching to a more flexible eSIM, such as Holafly eSIM, designed for reliable international travel without roaming complications.
