    Hi ​@William1903,

     

    We are so sorry to hear of the issues that you are currently facing. Please try the steps below, depending on the type of phone you have:

     

    For Android:

    1. Open Settings
    2. Tap General Management
    3. Tap Reset
    4. Select Reset network settings

     

    For iPhone:

    • Go to Settings
    • Tap Phone
    • Tap My Number
    • Delete the old number
    • Enter the new/current number
    • Tap Save

     

    Then follow these steps to refresh iMessage:

    1. Go to Settings
    2. Tap Messages
    3. Turn iMessage OFF
    4. Go to Settings > General
    5. Tap Reset
    6. Choose Reset Network Settings
    7. Once your iPhone restarts, go back to Settings
    8. Tap Messages
    9. Turn iMessage ON again

     

    Your iPhone should now recognise the SIM and verify your number to get it working again.
     

    Regards,

    It's a brand new Samsung S26

    I've done all the suggestions

    I put the sim into another phone and it worked fine so somehow the S26 is retaining the old number

    Hi ​@William1903,

     

    If the SIM works correctly in another phone, that suggests the issue is with the Samsung S26 rather than the SIM or your iD Mobile account.

     

    At this stage, please try the following:

    1. Go to Settings > General Management > Reset.
    2. Select Reset Mobile Network Settings.
    3. Restart the phone.

    If the old number is still showing:

    1. Open Google Messages.
    2. Go to Settings > RCS Chats.
    3. Turn RCS Chats OFF.
    4. Restart the phone.
    5. Turn RCS Chats ON again and allow it to re-register.

     

    You should also check whether there are any inactive SIM/eSIM profiles stored on the handset and remove any that are no longer in use.

     

    As the SIM works correctly in another device, if the S26 continues to retain the old number after the above steps, we'd recommend contacting Samsung directly, as this would indicate a handset software issue rather than a network issue.

     

    Regards,
