    Hi. I own an S5 from T-Mobile and accidentally upgraded to Lollipop. What a mistake! I'm planning to jump the board and get a Note 4. My question is what are the cons of buying an ATT Note 4, unlock it, and use it as T-mobile? I don't plan to update to lollipop on my Note 4, will I have problems with my apps? Thanks for any help.

    You shouldnt have any problems with your apps at all. The only difference it will make is you will still have ATT bloatware apps on tmobile and thats it.

    AT&T uses LTE bands 2, 4 + 17 in limited areas, mostly Band 4.

    T-Mobile uses LTE Bands 2, 4 + 12, mostly Band 4 but they are quickly expanding Band 12 coverage where they own spectrum. Band 12 is more desirable than 2 or 4 because it carries farther and penetrates buildings better.

    So while the AT&T model will work OK on T-Mobile, if you're in an area that has or will soon have T-Mobile Band 12 you won't be able to take advantage of it.

    As for Lollipop, I like it and have not had any problems with it on several devices. But if you stick with KitKat you should not have any trouble.

    I hope I don't have any problems with 4G LTE.

    That said, a Tmobile phone will work better than an ATT phone, as far as 4G LTE is concerned? Am I understanding it correctly?

    A T-Mobile version will work better on 4G LTE as far as it will be capable of using T-Mobile's Band 12 if available in your area. The AT&T version will not. Band 12 is the best for performance. T-Mobile.com has a map showing where Band 12 is or will be available.

    Crashdamage,

    How much of a difference of speed lost, if I was to use an ATT Note 4 phone do you think?

    Not having Band 12 (if it applies to your location) is less a matter of speed and more a matter of where you can get a connection at all. With Band 12 you will get a connection in more places and better connections.

    That said, a stronger signal does make faster speeds, so in places where Band 12 is stronger than Band 4, 12 would be faster. Where both signals are strong, speed would be equal.

    From gsmarena.com:

    Model N-910W8 for North America

    LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700) - N910W8

    LTE 1, 2, 3, 4, 5, 7, 8, 12, 17

    I stand corrected. I thought for sure I had just seen where the AT&T version was different than the T-Mobile (besides bloatware differences) and did not have Band 12. Must be thinking of another phone. Sorry.

    One BIG disadvantage to using an AT&T Samsung phone is that the bootloader is locked. On a TMobile Samsung, it's not (yet). MANY people on AT&T are using TMobile or International models for that reason.

    So I can still get Tmobile updates even though I'm using an ATT phone?

    Using an ATT Note 4, I can still receive updates from Tmobile?
