Question

SIM unknown?

I currently have no phone service. In settings under SIM it says ID mobile, Unknown. It has done this a few times recently & usually sorts itself out if I restart or reinsert the SIM card. Nothing seems to be working today. I've tried cleaning the card & contacts & toggling in/out of airplane mode. Last software update was 26th April.

    Hi ​@mjc2 ,

    I’m really sorry you’re experiencing this.I completely understand how stressful it is when your phone suddenly shows “SIM unknown” and you lose service, especially when it’s happened a few times already.
     

    Please try the following:

    • Turn Airplane Mode ON for 30 seconds, then OFF
    • Go to Settings → Mobile Network → Network Selection and set to Automatic (or try manually selecting iD Mobile if available)
    • Remove the SIM, gently wipe it again, and reinsert ensuring it sits firmly in place
    • Restart your phone again after reinserting
    • Go to Settings → General → Reset → Reset Network Settings (this will refresh connections without deleting your data)

     

    Also check:

    • Does the SIM work in another phone (if possible)?
    • Are you seeing any “No Service” or “Emergency Calls Only” messages?
     

    If it still shows “ID Mobile – Unknown” after this, it may indicate a SIM failure or network provisioning issue, and we may need to arrange a SIM replacement or account refresh for you.
