100% T-Mobile phone. Insert your tmobile sim and everythings should work fine..

I had this phone for a week now and it DOES work with T-Mobile LTE. If I could post a photo here to show it to you I would.

Yes. I'm a T mobile subscriber and the phone works fine - have them change your sim card to the US version. Something called 3G H+ versus 4G will be your internet speed.

i have tmobile also. This phone only goes up to 3g. A 4g plan will still work just not at 4g speeds. I do just fine with the 3g.

Ma be the frequency, this model use 850/1900/2100 3G, perhaps T Mobile use 900/1900/2100 so you have to get de Model I8190 wich works with this frequencies or try to get S4 Mini quad band works in all the fequencies. I hope this coments had been helpfull for you. Best Regards.

Sorry, I could not tell you if it will work with your present service provider. I have used the phone perfectly with T-Mobile and Walmarts Family Cellular.

Oh, for me I had t-mobile. Uh? Service was ok. Really I think it was the device. It would cut off and on. The interface was laggy. Phone calls for me were clear. I had no issue with service other than not being able to receive sms messages

If I am correct as long as your sim card fits into the Galaxy 2 it should work but if you are not sure try contacting T Mobile and they will answer this for you. I know I have a T Mobile Galaxy 4 and I switched to AT&T and I switched the sim card to AT&T sim cad and that works!!

It should work with all mobile services that use sim cards, but some of the service's features could hinge on having their phone. T-Mobile's T-zone or myFaves, for example, would not work on an unlocked phone. Also, some accessories you buy from your service provider may be locked also and will not work. But that only affects the features of the phone, you would still be able to use the phone through your service provider to call people, text, etc.. The only services I know of that wouldn't work are Sprint PCS, Verizon, and Virgin Mobile, because they don't use sim cards. If your phone uses a sim card, go for it.

I am just wondering if this phone will get LTE with AT&T; or T-Mobile? I read on another comment that it would only get 3G service and not 4G or LTE :/

Unfortunately, I bought S4 for use overseas and on a services other than AT&T network. It worked with no issues. Regards
