PDP Authentication Failure (iPhones)

Important Note: These instructions only apply to our Voice + Data eSIM product

If you are receiving a "PDP Authentication Failure" or  error message, this may indicate that there was an issue with the installation of the APN (Access Point Name) profile or that there are conflicting settings on your device from another service.

To resolve the issue, please try following the steps below (please DO NOT delete your Mobal eSIM) and let us know if any issues persist -

1. Go to Settings > General > VPN & Device Management and delete any APN configuration profiles that are shown.
   
   
2. Switch off your domestic SIM/eSIM, ensuring only our eSIM is active.
   
3. Reboot your iPhone handset to refresh the connection.
   
   
4. Connect to WiFi and then use Safari (do not use an alternative browser) to Download the APN Profile found at the following link: APN Profile Download
   
   
5. Go to: Settings > VPN & Device Management > Select the profile > Install
   
   
6. Go to: Settings > Cellular/Mobile Data > Cellular/Mobile Data Options > Voice & Data > Select 4G / LTE option

If any issues persist after completing these steps, please switch the "Flight Mode" / "Airplane Mode" feature on for 30 seconds and then disable it again to see if this resolves the issue. 

If there is still no change, please reboot your device to refresh the connection and then retest again after a few minutes.

If your issue still persists please go to Settings > General > Reset (or Transfer or Reset iPhone) > Reset Network Settings and then repeat steps 1-6 above.

Note: Clicking Reset Network Settings will erase all saved Wi-Fi networks and passwords, as well as any VPN or APN settings you've configured.
