[Q] Tmobile or unlocked version? Which one?

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...

So let me get this straight, the international gs3 is the unlocked version?

Well in this case what is different between the tmobile version and the unlocked version. Im not understanding, sorry. If I get the tmobile version, would i be able to use it the same way the unlocked version can be used?

At&T version on Bell

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

Thanks. Can anyone confirm this?

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

No you can't. The LTE frequencies are different.

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.

No they aren't.. same thing.. you can flash a AT&T modem on a Bell phone, hence, the same.

I am running the latest att firmware on my bell phone so no issues

LTE on Rogers?

Just wondering if the phone would support LTE in Roger's network in Canada with Tmo's baseband.

Out of the box it should support HSPA+ on Rogers if it is unlocked, however LTE is software locked, but I have heard of people flashing the Rogers/AT&T ROM onto their T889V and getting LTE. Hope that answers your question.

As long as you're unlocked, it should be fine. Might have to flash a modem for better reception.

Just to confirm I do this with my unlocked at&t s3 with no problems at all...stock modem working great. I use three for a carrier when in the UK

[Q] Unlocked ATT S3, switched to Spanish carrier, still safe to root?

I had my phone unlocked through ATT's service, and I'm currently using a SIM from Tuenti, which piggybacks off of Movistar's network. Do I still use the ATT images to root my phone, or will this screw up my cell coverage?
Thanks,
Victor

If you are using an AT&T branded S3 then use only d2att ROM's.

USE D2ATT roms. You might have to put in a custom APN to get mobile data.
