    Hi ​@John Ingledew 

     

    Thank you for getting in touch. I can certainly help with activating your replacement SIM while keeping your existing number.

     

    You can activate your replacement SIM using the iD Mobile app by following the steps below:

    1. Log in to the iD Mobile app
    2. Go to the Plan tab
    3. Select Your SIM / eSIM
    4. Tap Activate a replacement physical SIM
    5. Enter the 19-digit number found on the SIM card holder
    6. Select Activate

    Once submitted, activation usually completes within around one hour.
     

    If you’re unable to activate the SIM via the app or need further assistance, please contact our Live Chat team and they’ll be happy to activate the SIM for you.
