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.

    Hi ​@bendzel 

     

    Okay, did you insert the iD Mobile SIM into the device before the transfer took place?

     

    Have you tried a full device factory reset?

    I have done network reset, but did nit do device factory reset as it does not make sense.  Got feedback from Apple and there is wrong CLI. ID mobile need to sort it out.
