Hi,
I’ve tried all the guidance to get iMessage & Facetime working since switching to ID & porting my old number but nothing works.
iPhone 17 pro max with latest iOS
Getting fed up of having to keep resetting phone but even after full reset and entering my number in mobile service, it's not working. Some issue with port in. Please fix.

Already tried with a new esim and that too didn’t helped.

Hi @rkv,

I'm really sorry to hear you're experiencing issues with your mobile number. Please try the steps below to resolve this issue:

For iPhone:

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

Then follow these steps to refresh iMessage:

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 now recognise the new SIM and verify your number.

Regards,

Hi Gemma
I tried this already.
Please note I also did a complete reset and it didn’t helped as well.
Please note this a issue with porting as I also have other number with id mobile where I didn’t had this issue.
Kindly help check porting. Usually the phone number should auto populate from network provider.
