Can’t change number in iPhone “my number”

[TomFi]

I can't seem to change my number in my iPhone settings. I have tried an incredible amount of times, and have continued to reset my phone as suggested in here.
However, nothing is working. 
I assume it is responsible for the fact that I can't send text messages.

Since changing to Sky, everything else has worked great. However it is just text messages that I cannot send / cannot change my number in settings.

You could try ordering yourself a replacement sim to see if that helps:

Hi @TomFi  just checking you are trying in settings, phone, my number ? That's where you need to change it.

Hi @63johnw 

Thanks for your reply.

Yes that's the one I'm trying in.
I have tried the number by starting with the +44,,  07 , 0044, and none of them work. I have tried numerous times, over days/weeks now.

Everytime I save the number and it returns to the phone page, the number has remained as the original, and not my transferred number. 
very frustrating!

Thanks @caesarome 

If I order a replacement, does it send it with the 'transferred' number as the programmed number  (ie my current number now, as opposed to the one I started the phone with)? If that makes sense?

If Sky have told you that the number has been transferred to their sim then if you order a replacement it should come with the number you want to use, so the transferred one.

Hello. 
I'm having the exact same issue. How did you resolve this in the end?

I had to use +44 then omit the 0 from the number i.e.: +44 123 ******
