    I've heard of something similar happening to people when they use foreign sim cards.

    Anything going on with the sim?

    No, this has happened before on the iPhone 4S. 310-410 is the Mobile Network Code for AT&T.

    What's happening is that the phone isn't replacing the MNC with the network alpha tag right away, like it's supposed to. Slightly annoying, but harmless. There've been other threads about this.

    Thanks so much. I didn't have any luck searching. I thought it was harmless but just wanted reasurance as I have already had to have my SIM card replaced twice.

    Yep I did a little more research and what was happening with the foreign sim is as described as above. It would show the network code briefly then switch to say AT&T.
