My iPhone 4S number is unknown in settings?

I updated my iPhone 4S to iOS6 about a 2 months ago and every day since then my phone says searching for service when I know there's service so I go to settings then to phone and my number says unknown and won't let me put my number in it and I don't know what to do please help

Its simple: We burn the phone and get an Iphone 5.

Updating your phone always alter's some of the phone's settings. That's why your phone won't recognise your mobile phone's numbers.

  • Why does my iPhone not make a sound when I receive a text from an unknown number? When I get a text message from a number that is not in my phone, my phone lights up and shows that I have a text but does not make a sound or ring. Can I change that somehow? I have an iPhone 5.
  • Why did my number show up as unknown? I called my boyfriend and my number came up as unknown, even though I didn't call on private. Any idea why? I have an iphone 4.
  • Why did I get a text message from an Unknown number? So I have an iPhone 4 and I got a text message from an Unknown Number. Not a number that I don't know, it literally said "Unknown" where the number was supposed to be. There was no text in the message, and I responded with, "Hi, who's this?" and I got one of those error messages in return. What does this mean? How do you even send a text message from a blocked number?
  • Unknown number keeps texting me a blank message? A number keeps texting me a blank message, but instead of a number sending it to me, it simply says Unknown. I thought it was an error in something, then it happened two more times. Is it a person or just something messing up? I mean they're not saying anything, it's like they clicked the space button and sent the message. By the way, I have an iPhone.
