    Would an unlocked ATT 5s work on Verizon? I know it works the other way around (Verizon to ATT). I want to sell mine but I want to be sure not give my buddy any problems on Verizon.

    I don't think an AT&T phone will work on Verizon's network (locked or unlocked), though not 100% sure.

    You can just head out to a Verizon store and ask

    You can only use Verizon-branded phones on Verizon. The IMEI has to be in their database. So an AT&T or even factory unlocked iPhone will not work, even though they are technically the same model number with all the same antennas.

    The quick answer is; it would work. AT&T 5s to Verizon

    The new concept to grasp is that Apple made devices to have certain carrier bands and to have all models to have a LTE bands available.

    2G Network GSM 850 / 900 / 1800 / 1900 - all models
    CDMA 800 / 1700 / 1900 / 2100 - A1533 (CDMA), A1453
    3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100 - A1533 (GSM), A1453
    CDMA2000 1xEV-DO - A1533 (CDMA), A1453
    HSDPA 850 / 900 / 1900 / 2100 - A1457, A1530
    4G Network LTE- all models

    AT&T has the A1453 GSM model, however all models of the iPhone 5s have LTE bands, so it would work on Verizon
    -the reverse-
    Verizon has A1453 CDMA model, however all models of the iPhone 5s have LTE bands, and can work on AT&T's 4G LTE network.

    The quicker answer is no, because Verizon will not activate any device that was not OEMed for them, as noted above.

    ....
    The quick answer is that it "could" work from a technology standpoint.

    Real answer is that it WON'T work because as noted above, Verizon will not allow the device to be activated on their network.

    New concept to grasp.

    Has anyone actually tried though? I have a verizon 5s, and swapped sims with a coworker, want to say his was ATT, may have been Sprint, by my phone did pick up his sim card and signal. Didn't try making calls or anything though

    A Verizon iPhone 5s will definitely work on AT&T. Lots of people have done it. No problems.

    It will not work on Sprint. Period.

    And it will not work in the other direction. You cannot use an AT&T iPhone 5s on Verizon.

    I know this is an old thread... and I know that the iPhone 6/6s have different internals than the 5s...

    However I have an iPhone 6+ that was originally LOCKED to AT&T. It has since been unlocked through a request to AT&T (hooked to iTunes to complete unlock upon iPhone restore.)

    I have a coworker who has a Verizon 5S and I put his SIM in my iPhone 6+ and to my pleasant surprise upon reboot it said "Verizon LTE" and also had all the cellular data/voice working perfectly through his Verizon SIM. I popped my ATT SIM back in and it works with ATT still, as well.

    SO... I'd imagine the "point" of saying that Verizon wont activate a phone that was not "originally" made/registered for/to Verizon is incorrect, at least for the 6/6+.

    Again, an old thread, but possibly will help someone while searching...

    Yes. Totally different situations.
