- lyrrad 8y agoAT&T didn't allow those with off-contract iPhones to unlock them until April 8, 2012, so there was a few years there where you could have a paid-off device still locked to AT&T. https://www.macrumors.com/2012/04/06/att-will-unlock-off-contract-iphones-starting-sunday-april-8/ https://www.macrumors.com/2012/04/06/att-will-unlock-off-con...
- astura 8y agoThis wasn't initially the case with the original iPhone. I might be remembering wrong, but I think the original iPhone has some sort of technical constraints working on T-Mobile's network even if it was unlocked.
- paulmd 8y agoMight be because T-Mobile is on a different set of bands (that iirc are closer to the bands that are used internationally).
- astura 8y agoYes, that was it IIRC. I recall that using the original iPhone/early model iPhones didn't support the bands that T-Mobile used for 3G(?) so you were limited to 2G on T-Mobile. My memory is fuzzy and its something difficult to Google.
- post_break 8y agoAnd at the time the 2G on TMobile was just as fast if not faster than ATT 3G which was ironic.
