A PDP (Packet Data Protocol) Authentication Failure is an error that may appear when your device is trying to connect to a mobile network using an eSIM. This error means the network cannot verify your device credentials.
What to try
If you receive a PDP authentication failure message, follow the steps below:
Confirm that your device is compatible with eSIM and that your eSIM has been fully activated.
Check that the APN settings for your eSIM are entered correctly in your device network settings.
Make sure your device software is up to date.
Restart your device and try connecting again.
Causes of PDP Authentication Failure
The PDP protocol controls how data is sent and received over a mobile network. An authentication failure occurs when the network cannot confirm your device details. This can happen for several reasons:
Incorrect or outdated network settings
If your APN settings are wrong or outdated, your device may fail to connect. Confirm that the correct APN is entered for your eSIM.
Network coverage issues
Poor signal strength, network congestion or unstable coverage can prevent your device from establishing a data session.
Device related issues
Software or hardware issues on your device may also prevent the connection from being authenticated. Keeping your device updated helps avoid this.
