[Q] T-Mobile Galaxy SII on AT&T?

Sorry if this is a stupid question, but will my T-Mobile Galaxy SII T-989 work on the AT&T network with full service 4G if I unlock my T-989? Thinking about switching providers and wanted to know if my phone will work.

yeah thats what i heard..i dont know about 4g but i think it wil go ful speed 3g for data.. so yeah.

3G yes. 4G as in HSPDA yes, 4G as in LTE no

Actually the T-Mobile GS2 has LTE radio in it. At least anytime you plug it in to the computer it registers as an LTE composite device.

I wondered about 4G LTE. I was in a service setting menu and there was an option to change the band to LTE. Not sure if the phone has the capability but the option in the menu is there.

the T989 (hercules) DOES have LTE bands/radio capabilities. tmous is planning on launching their LTE network...soonish (knowing tmo, more like eventually)

in theory...yes, I don't know att's LTE band preferences, but we have the hardware for LTE.

That doesn't mean anything, you don't have the hardware

At&t galaxy s3 to T-Mobile help

I been thinking...instead of messing with all that and end up with a brick, why just not sell it on ebay and buy an actual Tmobile one or maybe trade with someone willing to. I would look at the selling price for an AT&T GS3 on ebay and how much would a Tmobile run and if it's not that much difference then pay the difference than end up with a possible brick. Plus I have read some forums where if you flash some things that are not meant for your phone you can even mess up the IME on your phone with no way to flash it back at the moment until someone comes up with a solution for it.

Not trying to be a jerk. Just a friendly reminder that this is not development related and needs to be in general or QA. I would repost there and report your thread to a moderator before the pitch forks come out.

When I put my friends note to t mobile it was the modem you had to flash , if your set on doing it , read a bunch on ways to do the note WITHOUT a custom Rom then find the same files you use in that ( the modem and if I remember right there was one other thing ) then go to the t mobile section in the sgs 3 thread and ask for help finding those files , but do a lot of reading first cause it would be a shame to brick your awesome phone

buy the t-mobile version. it doesn't work hardware not supported

im looking into this as well, i had the att note and flashed the tmobile modem worked like a charm so now im looking to do same with s3. if i find anything ill let you know

I don't thonk it will work at all. Att's S3 is LTE, correct. Tmobiles is not. Two different hw radios used.
If you do try it please post your results for others!

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.
Sent from my SGH-T999 using xda app-developers app

Have you guys tried the radios in the dev section by wildchld? I'm not sure it will work either but maybe worth a try. It has a script that backs up current radio and you can revert back. Atleast on T-Mobile s3 it does. Just need to reflash the restore zip to go back to previous radio. Again try at your own risk. There's a huge chance you can brick your device.

I don't think it matters if the Gs3 from T-Mobile doesn't have LTE, I used to have my Galaxy s2 skyrocket with LTE running on T-Mobile 3G/4G off a GS2 Hercules Modem.

Then by all means, give it a shot. I have no problem being proven wrong on stuff like this!
Just remember that was a different phone. And tmobiles radio Im pretty sure was confirmed to NOT support LTE. So they are different.
I'm definately looking forward to hearing someones results after trying! Just do some research on the two radios, and make sure the sw modem is on the same partition for each phone. (I think it will be. But if its not you could end up with serious problems)
Good luck to whomever tries it!

Probably won't, the T-Mobile phone is pentaband so it will run 3/4G on AT&T, but their version isn't. Try it though.

Epic 4G Touch 4G ?

I have not had 4g working on my Epic at all unless I was all the way on the other side of town. Now I know for a fact that LTE is not in my area but for the hell of it I activated my old LG Viper LTE and what do you know, I have constant 16 meg download on 4g. Anyone here that might have an idea of why this is? I really want to use my epic but wow this 4g stuff is nice too.

the 4G in our phone is on the wimax network, not LTE

:facepalm:

I 100 percent understand that, that's the reason I was confused because sprint has not setup lte here yet.

Maybe you got lucky and caught them during a trial period lol. Or your roaming on another lte network but idk if that's possible or not. some one else could clarify if it is possible

No I don't think that's possible... I'm pretty sure that Sprint and Verizon (or anybody else) would use the same frequencies for their 4G... they want it to stay fast... trial period is most likely

This Network Vision thing Sprint has been talking about is real. Lots of new LTE towers up recently all over the country. And no there is no 4g roaming between carriers.

4g LTE roaming is not possible between any of the carriers.
ATT LTE uses low 700mhz block & in the future, some AWS and WCS.
Vz LTE uses upper 700mhz block & in the future, AWS.
T-mobile LTE is AWS
Sprint LTE is PCS 1900/ SMR 800 / BRS-EBS 2.5/2.6ghz

I will give sprint a call tomorrow and ask because I need to know if I need to get a good lte phone. Can't even get any 4g on this phone.

It could be up and not announce it yet. Same as Here in my area (Arecibo PR) LTE is up and running but not officially announced. Even if you call CS they will negate it's up. Only officially available west of PR.

Just use sensorly and open signal it'll show you exactly where towers are and their broadcast bands (1x, 3g, lte, wimax) and coverage range

It has been confirmed by sprint that lte is in my area and 3 more towers are still being worked on. Just ordered my G Nexus.

Except it came out 9 months ago and the nexus 4 has already replaced it. Its got a weak camera, low RAM, poor display and did I mention it's old. If it was any phone but a nexus it wouldn't be getting updated anymore and headed for EOL, which it will be EOL less than halfway thru your new contract

My wife has a nexus. Its not bad but it came out before the e4gt. Hers is the verizon version. It does run good for having inferior cpu. Lte radio is a plus. No gorilla glass! Shes shattered 2. Overall great phone just lacks features from s3, but its basically free now. Lte is being built in my town now. So maybe few months and its live letd hope s4 is out.

Using my T989 on AT&T

I am going to be passing down my unlocked S2 to my girlfriend that is currently(for now) on ATT. I am running "Jedi Bean" now and just like everyone else on a 4.1 ROM, I dont have signal strength bars.
My question are:
*Is there anyway for me to get Signal strength bars with a T989 on ATT?
*Should, or could I even, flash an ATT radio? Would it help reception on ATT?
Please give me some ideas as to what I can do to make my T989 run as flawless, and as "normal", as possible on ATT's network.

U will only get 2g speed I would recommend selling or trading for a skyrocket

I know it cant get 4G, but I thought the T989 is capable of 3G on AT&T, it has the band for it...The main reason I am giving my girlfriend the S2 is so she can have all the Samsung apps and enjoy a better phone than she has; currently an HTC Inspire. I dont want to sell/trade it is because its my spare phone now that I sold my Galaxy S.
Side note: My girlfriend barely uses data, so the reduced speed is not a big deal.

It gets 3g on at&t because occasionally when I go out of my hspa 4g range like in middle of nowhere my phone will link up to an at&t tower on the edge network which is technically 3g. Sometimes its gprs 2g but it does get 3g on at&t signal.

If i could piggy back off this thread, I also have a tmo s4 on att network. Yesterday I was with a friend who was also on att and I noticed his phone at that time had 4g where the network bars were located, mine however read H+. It was then I realized that I have never seen the 4g symbol on my phone ever. Do I just not get 4g? Or does this ROM that I have on my phone (slim bean) either not have the files for 4g or maybe its originally a T-Mobile ROM so I'm not getting 4g I don't know. I do get LTE tho.

Ok this makes sense, thanks.

I had the same issues. If your previous phone that you used on AT&T was only 3G (I had an iPhone 4), your SIM card is only configured to receive and transmit 3G data. You will need to go on to wireless.att.net and order a new 4G SIM card, or go to a store and have them program one for you. This is assuming that you have already signed up for one of the new data plans, if not, they will likely not issue a SIM card capable of 4G and will probably hound you via email and SMS about using a 4G device on an old 3G data plan.
