At&T version on Bell - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

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

[Q] Can you use this on AT&T network and vice versa when unlocked?

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?

[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...

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?

[Q] Rogers S3 on Bell network?

I just did a quick search, and couldn't find the exact answer (probably not using the right search terms).
If I got a Rogers S3, what needs to be done for it work on the Bell network?

You'll need to unlock the network first.

Rogers to Bell s3
Once unlocked, download selfserve and also make sure you have a Bell LTE MicroSim.
Than happy rooting or whichever way you decide to go!
Root. Unlock. Lte sim. Lte data plan. Lte provisioning.
I have the same thing. Rogers s3 on bell/virgin. Tho I an having issues with Lte but I think its a tower in my area.

wow you made that sound difficult could have just left it at unlock network and been done with it! You don't have to root first either.
Sent from my SGH-I747M using xda premium
No you don't have to root lol just unlock.
But for Lte to work you need to make sure you have you correct data plan, sim card and provisioning.

4G data on an ATT GS3

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?
Maybe you should try posting in the ATT S3 forums? I'm pretty sure that most people here have the TMO variant, while you are looking for tweaking of the ATT variant.

Don't flash a T-Mobile modem, it will brick. T-Mobile and AT&T use different frequencies for hspa+ in most places, and the AT&T version doesn't have the hardware to pick up the most used T-Mobile frequency I believe. So you're probably stuck with edge

You ARE stuck on edge.... I know it sucks. unless you are in a refarming area http://www.airportal.de/ , (major cities) your AT&T S3 1900/2100Mhz high speed data (4G) band will not work on T-Mobile's 1700/2100Mhz networks. I would sell it on e-bay or craigslist and got your T-mobile S3 again. or get the T-Mobile S4 after you sell your att S3 :cyclops:
