Okay, I just spoke to tech support at ATT. The man I spoke to told me that the phones come with the ATT sim card, but it can be removed and the phone used on any other GSM network. He said if the phone did prove to be "locked," all one had to do is let ATT know, and ATT would "unlock" the phone. I hope this is true. Wish I had known this before.
Well, I just purchased a brand new in the box 5s that is ATT issued. Seller promises I can use the phone on any network. Plan to take it to Cricket this weekend to see if they show it unlocked. If not, I will go to an ATT store and ask to have it unlocked. If I cannot get it unlocked, it goes back to the seller. Will let you all know what happens.
Okay, my brand new, sealed in its box 5s arrived in the post today. I belled ATT to get them to unlock it. Last week one of their tech support people told me that it could be unlocked, no problem. Today, I was told that it cannot be unlocked unless it was first activated with ATT (contract) and was paid for two months. Then, another ATT customer service person told me six months.
Next, I contacted Cricket, which is owned by ATT. The store manager told me that the phone would work on their network. I asked what if I wanted to go back to Metro in six months or a year or whatever? Would the phone work on another network down the line? He said yes.
