iphone 5s has no service?

[Maximus831]

I did a cross upgrade at ATT last night and got home with the phone working perfectly. This morning, I wake up and the phone has no cell service from ATT. I tried a restore and it does not work. Any ideas? Wifi works but I do not have any service from ATT. Perhaps it's time for a trip to the ATT store?

Just call AT&T. I'm sure they messed something up.

Bad SIM card, just replaced it. Thanks.
