iMessage still showing temp number following porting process over from Sky mobile

[Chriskauto]

After 8 days, it finally seems like my phone number / calls have ported over from Sky but my iMessages are still showing the temporary number and not the number I've moved over to keep, how do I sort this out?

Phone settings>>Phone>>My Number

Change to correct number, save and then reboot phone

Did that work for you @Chriskauto?

I’m having same problem, it won’t save and still shows temp number
