I transferred my number from O2 to iD Mobile using a PAC code. Outgoing calls, texts, data and WiFi work, but incoming calls do not work at all. When somebody calls my number, the call instantly ends and I do not receive a missed call notification.

iMessage and FaceTime activation are also saying my number is not associated with this phone yet. I have already restarted my iPhone, reset network settings, turned iMessage/FaceTime off and back on, and reinserted the SIM.

Is my number port incomplete and can somebody refresh/re-provision the SIM or incoming call routing please?

Hi @lilylouiselaw,

Thanks for getting in touch, and we’re sorry to hear you’re having issues after transferring your number from O2.

What you’re describing is a known issue that can sometimes happen shortly after a number transfer, where outgoing services work correctly but incoming calls and Apple verification services do not fully update.

Please try the following steps:

Go to Settings
Tap Phone
Tap My Number
Delete the old number
Enter your transferred number
Tap Save

Then refresh iMessage and network settings:

Go to Settings
Tap Messages
Turn iMessage OFF
Go to Settings > General
Tap Reset
Choose Reset Network Settings

Once your iPhone restarts:

Go back to Settings
Tap Messages
Turn iMessage ON again

Your iPhone should then recognise the correct number and attempt to verify it again.

If incoming calls still do not work after trying the above, please contact our Live Chat team so they can investigate the number routing and SIM provisioning further.
