Hi ​@Elizabeth Dove.

Thank you for sharing. To manage your new contract in the app, please make sure the details on the new plan, such as your full name, address and email address, match the details on your existing account. You can then add the new number to your account by following these steps:

On the ‘Home’ screen, tap ‘View your plans’ in the top right of the screen.
Tap the ‘Add new plan’ button.
Enter the mobile number for the plan you wish to add. The number must begin with 07 and be 11 digits long.
Enter the last name and date of birth of the account holder, then tap ‘Next’.
You will receive an SMS with a one-time passcode to the iD Mobile number you are adding.
Enter the 8 digit code into the boxes displayed on the screen.

Thanks,

Marquerita
