The "PDP Authentication" error can be due to your settings or the data/validity of your eSIM. Please check if the following points apply:
-
The APN is set according to the information on your eSIM installation page (all in lowercase and as one word).
-
You still have remaining data on your eSIM: If you try to connect when no data is available, this error can occur.
-
You are connected to the supported network as indicated on your eSIM installation page.
If the above steps do not help, please try resetting your network settings:
- Go to Settings on your device.
- Select General.
- Tap Reset.
- Choose Reset Network Settings.
- Restart your device.
