Got an iPhone 4S from the Apple store. 

Decided to get new XT Prepaid.
had $10 credit, tested txt n call. it works.
I realise that on my Settings > Phone > My Number showing Unknown.
can't click the Unknown for edit.
It's the same on iTunes > Phone Number N/A 
try Reset All Settings & Erase All Content and Settings on the phone n still the same.

Chuck in a voda n 2d sims, both showing the number on the phone and iTunes.

hope anyone manage to help. Thanks



not sure is this the right forum maybe this is Telecom or Apple, if wrong please moved to correct one.
