“PDP Authentication Failure” can appear on iPhone when the phone has signal but cannot establish a working cellular-data session. It does not refer to your Apple Account or website password.
Select the correct data line
- Open Settings > Cellular or Mobile Data.
- Tap Cellular Data.
- Select the EasyTripGo eSIM.
- Turn off Allow Cellular Data Switching to prevent the home line from taking over.
Enable data roaming on EasyTripGo
Open the EasyTripGo line, choose Cellular Data Options and turn on Data Roaming. Keep data roaming off on your primary SIM.
Check the APN
Open Cellular Data Network if the option is available. Enter the APN exactly as shown in the EasyTripGo delivery instructions. Do not add spaces or enter an APN found randomly online. Leave username, password, MCC, MNC and APN type unchanged unless specifically instructed.
Some eSIM profiles configure the APN automatically and do not allow editing. Read what to do when the APN is missing or locked.
Reconnect to the network
- Turn airplane mode on for 30 seconds and then off.
- Restart the phone.
- Wait up to two minutes for the network to return.
- If the plan lists several partner networks, test a supported network manually.
Check the plan status
Confirm that you are in a covered destination and that the plan has remaining data and validity. If the plan is exhausted or expired, purchase a new plan for the correct destination.
For full APN instructions, see how to check eSIM APN settings.
