I normally order from att premier and they have always come with a SIM card, but this time ordered from Apple. The phone came yesterday with no SIM card in it. I had to take it to ATT to get one since my 4s does not have a micro sim to swap. ATT said they had never seen that before and that the only phones shipped without a SIM are unlocked phones. Did apple send me an unlocked GSM phone or is this normal for them to come without a SIM card?
