Looking to move over to T-Mobile prepaid from Verizon in the near future. I've been doing all sorts of reading. Basically my question is if I buy an unlocked Galaxy S3 off of Amazon or wherever else, will the sim card work, and will I get 4g speeds? Thanks.
Yes, if you get the T-Mobile version of the phone. If you get any other version, you will not likely get 4G speeds on T-Mobile.
The unlocked one on Amazon is probably the UK version. Make sure it is the T-Mobile version.

Thanks for the responses. The one on amazon says GSM and the model number is listed as GT-I999RWDBTU. Would this be the T-Mobile version?
T Mobile version is SGH-T999 or just T999

Hi,
I basically want to know if there is any difference between these devices, other than network provider lock.
Can you use the ROMs interchangeably?
I think the tmo model does support att's bands and u can probably interchange roms as well like on the tmo s2 and the skyrocket

We don't know for sure yet that the ROMs will be interchangeable. However, given that most T-Mobile phones support the 850/1900 NAM bands (GSM) needed for AT&T HSPA+, as long as the phone is unlocked it should work fine.

In thinking of doing this. Does anyone know if it works with the Medianet data plan?

The Galaxy S2 did. Reading the specs page on the Tmobile website, I've come to the conclusion that the bands are identical to the AT&T variant's. I'm going to be doing the same thing.
Will hspa+ work? If so, tmo users who will be paying full price would be better off
Buying from att because its less than tmos full price cost.
Plus wireless tethering would work Because tmo doesn't have imei # of att phone.
Can anyone confim?
i would like to know this as well, paying 549 if a lot better than 639.

FYI only T-MO has HSPA +42 version of the S3 for those looking to buy from At&t.
anyone can confirm this?? does the gs3 from tmo works on att HSPA+ and vice versa and if the tmo gs3 works internationally on 3g networks.
All right,unlocked my T999 galaxy s3, put my AT&T micro sim in phone but I get no data. I can make phone calls no problem.Do I have to do anything with the APN settings?
Thank you!!
You need to make an AT&T APN. Also the AT&T version will not get 3G on T-Mobile without at the very least a modem flash.

O.K. just added a couple ATT apn settings still no data.any other suggestions?
By the way i have a 4g micro sim.Thought Tmobile S3 had ATT hspa+ bands.
Got apn settings from these forums.
Might want to do a lot of research before trying to flash an att ROM on tmo or vice versa. I heard the tmo phones are quad core.

did you flash an AT&T radio? you will probably need to do that.
how did you unlock your phone? did you just buy a code or did you try one of the XDA methods?

I will most likely use this phone on Simple Mobile which uses tmobiles towers so the obvious choice would be the tmobile version, but would i benefit in any way by getting the unlocked version? Who is the unlocked version branded by? I dont want to make a mistake because a month ago i was about to get the unlocked iphone for my girl and run it on simple mobile until thankfully you guys tipped me off that the unlocked iphone was actually an at&t branded phone and will not get 4g speeds on simple mobile.
So, who is the unlocked version of the gs3 branded by? And which one should i get, tmobile gs3 or unlocked gs3?
International Sgs3 is branded by Samsung. I believe you would not get 4g, because of the different frequencies. The other option would be the Korean version of the sgs3. I do not know if that works though.
T-mobile is gonna be updating their 1900mhz which means the international s3 will get 3g data and iPhone users same...

I asked this question over on androidforums.com, but I did not receive a definitive answer. If I purchased a used At&T GS3, would I be able to use it with full LTE functionality on the Bell Canada network if I unlocked it?
Thanks.
I would imagine us they're the exact same phone both i747

Well you can use any unlocked phone on Bell. So basically it should work

I can confirm that they are exactly the same hardware. You could flash the bell firmware from Samfirmware on the AT&T version, and it would be identical to what you get from a bell store here in canada. The LTE Frequency for AT&T is different, as another poster noted, but the Radio firmware for Bell would make it work.

Someone may correct me but I don't think HSPA+ will work on ATT. They use different frequencies. If you had the international SGS3, HSPA+ would work on ATT.
OK thank you, I'll pass on the GS3, I'll just keep my iphone
It works. T-Mobile s3 has the frequencies needed. My s3 is T-Mobile unlocked and using it with at&t.

+1. The T999 supports 850/1700/1900/2100 for HSPA+. Therefore it will work on Atts H+. I use both T-Mobile and straight talk on my t999.

I assume that is something to do with at&t if so, you would have a better chance asking there.
Until recently I have been with Sprint. And I am located in South Florida.
I am considering going with Simple Mobile as I'm told that T-Mobile has one of the best data speeds in this area. And I want to get a Galaxy S3 as the phone to use with this service.
Can anyone here advise as to whether this would work with Simple Mobile (I called them but they won't say anything only that they don't don't support it - meaning they don't sell it so don't bother them), at what speeds?
I also assume that I must get the T-Mobile version of this phone. That seems quite difficult unless I want to pay a big premium to T-Mobile, who charges much more than say AT&T for their version. So if anyone has any suggestions where I can get one (I would prefer a store, not eBay)?
Thanks
try the xda marketplace
edit: nvm just saw you dont have enough posts.
I read that the Sprint variant of the S3 would work on T-Mobile. You just have to unlock the phone I believe.

I remember negri sells the phone for $599 unlocked. That's the cheapest I've seen for the TMobile version. It's not cheaper by much but it's unlocked and you may save on taxes.

Sprint is cdma and T-Mobile is GSM. How are you going to stick a sim card in that sprint phone?

My wife is using it on Simple Mobile. It works great.
Simple Mobile is a Mvno of t-mobile so you don't need to have an unlocked T999. Just change the apn. A's far as speeds. I live in Central Florida and I get the same speeds as t-mobile. I recommended. As far as where to buy the phone. I went to t-mobile and paid $599 for it. Haven't really seen it cheaper.

It does have a sim slot but it's not user accessible.
It's hidden behind the plastic under the battery.
Sprint has taken this approach with all there LTE devices.
The only exception may be the Photon Q since it's touted as being a global device.
