When you have an iPhone and a SIM card it is most natural to think that your own number will be displayed at the top. But with the iPhone and Apple, unusual is often the usual and sometimes in ways weird enough to drive you to nuts.  Several iPhone users and AT & T customers have found that.

Why? The number was not properly saved in the iPhone’s SIM Card.

Well, what to do?

One simple way is to insert the SIM in another phone, manipulate your contacts to find and enter your number.

Go the hard way. Contact AT & T.

Weird. But that happens with iPhone all the time. Ain’t it?
