Hi ​@Julia21809 ,

Thank you for getting in touch with us, I’m happy to explain what’s happening. Although your PAC transfer has completed successfully and your iD Mobile account correctly shows your original number, what you’re experiencing is usually a device or messaging sync issue, not a problem with the number transfer itself.
On iPhones in particular, this can happen because:
iMessage or FaceTime may still be linked to the temporary number that was assigned before the PAC completed.
Your phone may not yet have fully refreshed its network settings since the transfer.
To resolve this, please try the following steps:
Go to Settings > Messages > Send & Receive
Make sure your correct (old) mobile number is ticked
Untick any other number shown
Go to Settings > FaceTime and ensure only your correct number is selected
Restart your phone
If the issue continues, turn iMessage off, restart the phone, then turn iMessage back on.

On Samsung devices, this issue is usually caused by the Messages app or RCS (Chat messages) still being linked to the temporary number that was assigned before the PAC completed.

Please try the following steps:

Open Messages

Tap the three dots (top right) > Settings

Select Chat messages (or RCS chats)

Turn Chat messages off

Restart your phone

Turn Chat messages back on

Go to Messages > Settings > Advanced and ensure your correct mobile number is displayed

Thank you,

Zandile
