[Q] tmobile in att area, which sgs3 to get? - Galaxy S III Q&A, Help & Troubleshooting

I've been wanting an upgrade from my G2x for a while and what I want, which is what everyone else wants, is the Samsung Galaxy S3. I don't know which model to get, being that there are so many models of the S3 depending on the service provider. Here's the situation: I'm on a t-mobile value plan, living in West Virginia (I'm a student) with the only service here is roaming on AT&T, thus I only get edge. Can I use a different model, like an unlocked AT&T, and then be able to use more than 2G? Then be able to get full 4G when I do go to t-mobile service area? (From the chart by forum moderator, it shows AT&T shares 1900 mHz, 2100mHz, HSPA+, so it should technically work with tmobile, correct line of thought?)
*I already know that unlocked international version won't be able to get on anything more than 2G in US, it having different radios.
Also, read somewhere that I could buy the AT&T model and be able to use international LTE networks. Is that true? Could someone here enlighten me about the issues with the radios/frequencies (for US) for S3?
Much appreciated. Tried to find this question answered somewhere, and couldn't so posting now.

[Q] What Non-AT&T branded phones work on AT&T's 3G network?

I had read in a thread by azwildcat98 "We know that AT&T uses the 850/1900/2100 MHz US 3G bands, while T-Mobile uses the 1700/2100 MHz US 3G bands, therefore making each carrier's hardware incompatible with the other's 3G network"
I am looking for possibly a list of non-AT&T distributed phones that work on AT&T's 3G network. My reason is that I currently have a T-mobile HTC HD2 connected to AT&T's EDGE network and i am paying $10/month for "non-smartphone internet" (because AT&T and T-Mobile dont exchange their IMEI # database apparently) AT&T thinks i have a crap flip phone... So i dont have to pay $30/month for "smartphone internet." How can i achieve AT&T's 3G speeds while not purchasing an AT&T branded phone so i can continue paying for "non-smartphone internet'?
My problem could be solved by just buying an AT&T branded phone, but im saving $20/month my way.
The only answers I really want to see in this thread are: What non-AT&T branded Android smartphones are out with 850/1900/2100 MHz US 3G bands?

There are a few carriers that use the same bands. None in the US though. The Closest is Canada. Just a warning, the carriers and OEMs to prevent this sort of thing. While they can't tell what phone your using they are starting to be able to tell if its a smartphone or dumbphone.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
I finally found a non AT&T branded phone that has the 850MHz required AT&T 3G frequency! but i dont want that phone, any others?
http://pocketnow.com/hardware-1/how-to-get-an-htc-hd2-with-3g-on-att
Edit: I think i came to the conclusion that any unlocked phone will achieve AT&T 3G speeds if is has 850MHz, and i can get my "dumbphone internet" if the phone is "unbranded" or branded as a carrier other than AT&T.
HTC Sensation z710a (Unbranded) will work with AT&T 4G speeds! gonna try to get one and hope my $10/ month deal holds up... I figure im saving 12months x $20 = $240/ year without "smartphone internet" so i dont care how much i pay for the phone.

[Q] Unlocked SGS2/IMEI/ATT data Q

Hi all. I have searched and cant find an answer to my specific Q.
I am thinking of getting an unbranded/unlocked SGS2 To use with my ATT sim, which has an unlimited data plan for $10....old grandfathered one.
I am presently using an HTC HD2, which is a smartphone that ATT never sold, therefore the non smartphone data rate.
If I were to buy an unbranded SGS2, would ATT be able, through the registering of the phones IMEI on their network, to change my data plan to the more expensive data plan? I guess the question boils down to, in addition to all the IMEI's that ATT has for the SGS2's that they sell and have a record of, would they also have a record of unbraded IMEI's?
Isn't this the reason there is an AT&T SGS2 because the International one doesn't fully support AT&T? Maybe ask the question in the AT&T SGS2 forums?
Didnt know that there was an ATT forum! Thanks. And, the International SGS2 supports ATTs 3G network on the 850 band. That is why I want one....fully international on 3G...850/900 and 2100.
Found my answer on the ATT thread....I think. Looks like ATT will not know the international SGS2 is a smartphone as they wont have the IMEI's, I think!
Thanks.

[Q] can I use the international version in the UK?

Hey,
A friend that's down from the UK wanted to buy a phone here in the US, but I was wondering: will the international version (or the tmobile version) work fine there? His carrier is specifically Orange. I couldn't find specific information on what frequencies they use, so I thought it'd be better to ask. Thanks
If it's International it will work

Your title says "can I use the international version in the UK?", but your question seems to ask "can I use the international version in the US?"
The answer to both questions is yes.
I have the international version (i9100), and live in the US and have been using it on AT&T for quite some time.
It can also work on T-Mobile USA's network, but will only get Edge data speeds on that network due to T-Mobile USA using the AWS band for high speed mobile data. (the AWS band requires a band the i9100 doesn't receive)
Edit to add: I just re-read the line that says "A friend that's down from the UK wanted to buy a phone here in the US, but I was wondering: will the international version (or the tmobile version) work fine there?"... Does this mean he wants to buy a T-Mobile USA phone and try to take it back to Europe? I don't think I'd recommend that for the reason I cited above for why the i9100 doesn't work for high speed data on T-Mobile USA's network. T-Mobile USA's Galaxy S II variant is the SGH-T989, which is a totally different phone, that works on different frequencies. So I guess; can you ask your question a bit more clearly?

sorry for the confusion, but yes your edit is correct: a friend wants to buy a phone here, and take it back to the UK for use.

Hmm. Again, I wouldn't recommend it. From what I know, GSM carriers in the US tend to favor different frequencies (850/1900 on AT&T, 1700/2100 on T-mobile) than GSM carriers in Europe. (GSM 900/1800)
Some phones have enough band cross-over that they can be bought and used on the network he wants, but without doing extensive research into whatever model phone he is interested in, and also what band frequencies his carrier specifically uses, it would be a guessing game.
For example, I did about 2 weeks worth of heavy research before I bought an unlocked I9100 to use in the US on AT&T's network.
I've seen plenty of people buy the same phone to use on T-mobile USA, only to find out they can only get Edge data speed, and wonder why.

ironically, I did exactly did what you mentioned (tmo + international version). From what I gathered, It looks like europe does support GT-i9100, just the P varient, which seem to have the same exact hardware + NFC. So I think I can safely assume it will work, but I would rather get an answer from someone with more knowledge.

Um... I don't think you get it.
The I9100 is sold pretty much everywhere BUT the US. It's sold in the UK, in fact. Mine came from the UK.
The only difference between the I9100 and the I9100P is the I9100P has NFC hardware built into it, and the I9100 does not. Otherwise, the I9100 and I9100P operate on the same frequencies.
The US variants of the Galaxy S II are completely different hardware.
The AT&T variant is the SGH-I777.
The T-Mobile USA variant is the SGH-T989.
The Sprint variant is the SPH-D710.
The US Cellular variant is the SCH-R760.
(those last two are CDMA variants, and may not even work in Europe)
You can see nearly all the variants on the wikipedia page.
so it's safe to assume it will work, got it. thank you very much.

Well, if he buys an i9100, yes.
If he buys any of the US variants, not so much.

Big decision on whether to get the international or US Samsung Galaxy S3

Note: Posting this here because...this kinda concerns this version, tmobile, AT&T, and the US version. Not sure if this is the best place to post this topic though. If it isn't, please move it. Anyway
Edit: Dammit, maybe this thread is more appropriate for the Tmobile section. I guess I posted this in the wrong place then.
For the past two days, I've been undecided on whether or not I should get the International Samsung Galaxy S3, or the USA Samsung Galaxy S3. To the point where it's stressing me out.From what I've read, its a pretty debatable subject..and its tiring having to go through "lolz quad core owns all" or "2gb ram is the best. Lol international". I looked at some videos, and they seemed even, more or less.
1. Here is my issue. I have Tmobile.Right now I'm under a prepaid type of plan(as in, I pay for minutes whenever. If I'm out of minutes, I can buy some more at any time. I'm under no type of contract. And the only thing that obviously happens to me if I run out of minutes is that I cant call/text anyone until i add more ). But I would like the option to go to 3g/4g in the future. I don't have the money to do 3g/4G right now , but atleast the option is still there for the future. So for now , I'm on a prepaid "pay whenever I want" thing.
From what I've heard the international version does not support 3g/4g(?) regarding Tmobile. All I will get is edge. Now here is the question. Will this always be the case for the International version? Meaning that the international version will never support 3g and 4g under Tmobile?(if I wanted to get a 3g plan) ?
2. If thats the case, what about the USA version? If I decide to stick under Tmobile, and get the US version, I will still have the option of upgrading to 3G/4g on Tmobile, right ? If so, does it matter which US Samsung Galaxy phone I get?(ignoring Verizon and Sprint)
For example, I heard that the AT&T locks the user from disabling LTE for the USA version. As well as locks other things in general. Even if unlocked. Is this true? Or was the person who said this full of crap?
2.5 Also, lets say I do get The AT&T SGS3. And I unlock it and put my Tmobile sim card in it. Now in the future, If I wanted to upgrade to LTE, would I be able to get LTE on this unlocked AT&T phone under a Tmobile Plan? Or would I need an AT&T SGS3, along with an AT&T plan in order to get LTE? And would the reverse be true(as in, If I get a Tmobile SGS3, and wanted to switch carriers . I would never get LTE because of the change of plan). Should I only get a Tmobile USA Samsung Galaxy S3?
3.What about "rooting"? Would that be a way around #2.5 or any of the above questions?
4. Does AT&T have a good prepaid plan as well?(as in, I can pay for minutes whenever. I'm not under any contract or $30 a month type of thing)
5.In my situation, would you recommend I get the US, or international version? Is it worth getting the international version, or USA version when concerning Tmobile? Should I switch carriers in the future, or am I fine the way I am now?
?
6. IYO, if I were to get the USA version, what would be the best place to get it? Without any type of contracts. Again, I assume that buying it locked(and them me manually unlocking it) is the safest option?
7. In my situation, would you recoomend I get the USA, or international version?
Cliffs.
- Deciding between international SGS3, or USA SGS3.
- I'm under Tmobile(prepaid for now)
- Is it true that the International version of the SGS3 will never support 3g or 4g for Tmobile?
- If that's the case, I will at least have the option of upgrading to 3g/4g/on a USA SGS3 under Tmobile, right?
- If the above is true, would it matter which USA Samsung Galaxy S3 I get?(AT&T, or Tmobile). Ex: Is it true that AT&T locks/prevents the user from disabling LTE(which apparently drains a lot)pa, and other apps on the specific AT&T SGS3? Even if it's unlocked? Or was the person who said this full of crap?)
- If I do get a USA AT&T SGS3, unlock it, and put my Tmobile sim card in it. And in the future, wanted to upgrade to LTE, would I be able to get LTE on this unlocked ATT phone, under a Tmobile plan? If not, does the reverse hold true as well?(as in, If I get a Tmobile SGS3, and wanted to switch carriers . I would never get LTE because of the change of plan)
- Would rooting solve the above issues?
- Does AT&T have a good prepaid plan as well?(as in, I can pay for minutes whenever. I'm not under any contract or $30 a month type of thing)
- What would you guys do in my situation?
- IYO, if I were to get the USA version, what would be the best place to get it? Without any type of contracts
- In my situation, would you recommend I get the US, or international version?

I live in Germany on T-Mobile and have the International version. I recently travelled back to the US (PA/WV/OH area). T-Mobile only gave me a roaming Edge connection, no 3G (at least in the Columbus OH area). I went to the local AT&T shop to get one of the prepaid SIM's. They sold me one, but no-go on the data. They don't do "4G" data on the prepaid plan, the phone was too cool for them. I was only there for a couple of weeks, so I dealt with it. As for which is better, 2 core or 4 core, flip a coin. They are both good. Use GSM Arena's specs pages along with http://en.wikipedia.org/wiki/Cellular_frequencies for carrier frequencies to figure out which phone supports the data connection you want.

Ahh I see. Thanks for the input man Now that I think about it, i'm starting to lean more towards the US version.
also, are there any good guides on how to disable LTE on a US ATT SGS3?

[Q] Groupon S5 Deal: Work on T-Mobile?

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.
