    Hi Everyone,

    I am looking to buy an unlocked iPhone 5s with T-Mobile SIM card on launch day. Will the unlocked iPhone 5s be compatible with AT&T's LTE network when I switch the T-Mobile SIM card to my current AT&T nano SIM card?

    Thanks!

    According to the reports a single model of each 5s/5c supports both AT&T and Verizon, as well as T-Mobile.
    Sprint is the odd man out this time.

    The verizon phone will support AT&T and tmobile gsm. The AT&T and unlocked phones will not support verizon evdo.

    However, the Verizon iphone 5s will not unlock the AT&T or T-mobile LTE bands, just the slower GSM bands. So if you want unlocked that works with AT&T LTE, then T-mobile is the way to go.

    I am also buying the TMO 5S and throwing an AT&T SIM in there. I wouldn't even mind being on a new 2 yr contract if AT&T would just unlock the dang phone! I have a great grandfathered plan. I'm not going anywhere. Well, I do go overseas often which is why I need the phone unlocked. lol.

    This was an issue with the iPhone 5, not the 5s. The 5s includes all the necessary bands.
