If you see the message “This code is no longer valid” or “Unable to Activate eSIM” or "eSIM cannot be added" when trying to install your eSIM, it usually means the Travel eSIM has already been installed on your device.

Please check whether your Tesco International Travel eSIM is already installed by following the steps below, depending on your phone:

For iOS

Go to Settings
Tap Mobile Service (or Cellular)
Check if your eSIM is listed under SIMs. It may appear as “Secondary”, “Travel”, “Business”, or something similar.
If your new eSIM appears, you can turn it on whenever you wish to use it.
Make sure Data Roaming is enabled for that eSIM.
To select it for mobile data:
Settings → Mobile Service (or Cellular) → Mobile Data → choose your new eSIM.
To select it for calls and texts (if included in your plan):
Settings → Mobile Service → Default Voice Line → choose your new eSIM.

For Android

Go to Settings
Tap Network & Internet or Connections
Tap SIMs or SIM Manager
Check if your eSIM is listed and active. It may appear as “SIM 2”, “Mobile Plan”, “Travel”, or with your network name.
Select the eSIM as the preferred SIM for Mobile Data.
Select it for Calls and Messages if your plan includes these services.
To enable roaming:
Connections → Mobile Networks → Data Roaming → make sure roaming is turned ON for the eSIM.
