Will the T-Mobile 640 work on ATT

[Smidgerine]

I am wanting to switch to T-Mo, but I can't do it right now, but I would gladly replace my 635 media player with it. I would like to be able to use it temporarily on ATT, so just wondering if that would work. I realize I'd have to get it unlocked somehow, but I'm more wondering about the bands/LTE etc. on ATT.

I doubt it. The phone might work, but it would have to be unlocked first and you need x months of service before you can use it. Seems like it would be better to get an unlocked one or just wait for AT&T to release their variant.

It should, I cant post links yet but google t-mobile unlocked sim card policy and that should get you there.

These are the LTE bands my T-Mobile 640 support, of course your phone will need to be unlocked to work on AT&T.
