Issue with iMessage and FaceTime Activation After Number Transfer

Hello,

 

I recently transferred my mobile number from O2 to iD Mobile and received confirmation that the porting process was completed successfully. However, I am still unable to activate iMessage and FaceTime on this number.

 

The issue appears to be network-related, as I was able to successfully activate iMessage and FaceTime within minutes using a different SIM card. I have confirmed the following:

 

  • My number is correctly set in iPhone settings (Phone > My Number).
  • I can send and receive regular SMS and calls.
  • I can send an SMS to Apple’s activation number without issues.
  • I’ve tried all standard troubleshooting steps, including resetting network settings and reactivating iMessage/FaceTime.

 

 

It seems the problem might be related to the provisioning of my number on your network, particularly regarding Caller Line Identity (CLI) or SMS routing.

 

Could you please verify:

 

  1. That my number is fully registered on your systems after the port.
  2. That outgoing international SMS and CLI are properly configured for my number.
  3. Whether a new eSIM could help resolve the issue if the current one was not updated correctly after the port.
