If you see a "PDP Authentication Failure" message on your device, it means your Tesco International Travel eSIM cannot connect to the network. This usually happens for one of the reasons below.
1. Check if you’re in the correct country
- This error often appears when your Travel eSIM is being used in the wrong location.
- For example, if you purchased a Travel eSIM plan for the UK but are trying to use it in the US, your eSIM will not connect.
- Make sure you are in the country or region your Travel eSIM plan is intended for.
2. Check if you have used all your data allowance
- If your Travel eSIM was working normally but suddenly stopped and shows this error, you may have used up your data bundle.
- For instance, if you bought a 5 GB plan, the connection will stop once you have used all 5 GB.
