[Q] T-Mobile Galaxy SII on AT&T? - T-Mobile Samsung Galaxy S II SGH-T989

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

confusion then. why is it the first Samsung device to show LTE bands then... if it doesn't actually have the hardware then why do they show up? the t959v gs4g doesn't show them. why this one?

Yes this guys right. Take a look for yourself:
ATT Galaxy Note Specs
T-Mobile Galaxy S3 Specs
ATT Galaxy S3 Specs
Notice how the Note and the T-Mobile Galaxy S3 have that 1700 Mhz frequency? Thats what T-Mobile broadcasts their 3G/4G spectrum on. If the phone doesnt have those frequencies, then it wont work no matter what you do.

That's different. It is a whole different phone with a whole different SoC.
Let's not say things that we cannot prove.
Don't shoot this guy completely down. It will get T-Mobile 3g/4g as soon as T-Mobile refarms their network.

Yeah, because they live in one of the small parts of the US that uses the 1900mhz band for HSPA. It will not work everywhere else.

Yes, HSPA+ will be fine. But as you said, no LTE.

I'm hoping you fellas will help me out here.

I'm buying an unlocked T-mobile Galaxy s3 from a really nice guy. I'm on AT&T, and would like to A) confirm it will work on HSPA+, and B) I would like to know how to go about setting it up on the Medianet plan.

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.

T-Mobile / Simple Mobile / Galaxy S3 ?

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.
Sent from my S3
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?
Sent from my SPH-D710 using xda app-developers app
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.

Galaxy nexus 4g lte for AT&T?

Hey guys, i currently have a htc one x from at&t and development on there is like dead..
So i'm thinking of switching to the galaxy nexus since i had a nexus S and it was sexy and dependable.
what im looking for the a white galaxy nexus,
So the question i'm asking is, does this device support the 4g lte of at&t? if so, what would the model number be?
i know it does support 4g, but i cant find anything on the lte info on google
thanks for the responses
No LTE on At&t's Gnex.
No, in order to use it on AT&T you need the unlocked GSM model (i9250), which is HSPA+ 21mbps, not LTE.
And the two LTE variants for Verizon and Sprint will not work on AT&T. Just how it is.
ugh sadface...
how are the speeds on hspa?

Depends on your area, anywhere from 3mbps to about 10mbps. Why don't you turn off LTE on your One X and see?

Oh lol that's right. AT&T's custom firmware doesn't let you turn off LTE.

Unlocking Q

If I unlocked my Hercules and used at&t prepaid and flashed a skyrocket radio would I be able to use their data? And also would the data be just as fast?
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
Yes I think so might just have to change APN settings
How do you do that?
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
I'm not for sure you may not have to. I only know how to change APN on a iPhone. You should be OK with just an unlocked t989 and radio change
I believe you could use it, but it would only be 2g because at&t uses LTE for their high speed networks. The physical radio itself in our Hercules just doesn't support it.
Sent from my SAMSUNG-SGH-T989 using xda premium
But a att radio should fix that
No, not the software radio. That will give you the 2G signal, but we don't have the actual physical hardware to run full speed on at&t's network. That's part of why the Hercules has a different processor, the one in the international/att sII wouldn't work with tmo's hspa network.
Sent from my SAMSUNG-SGH-T989 using xda premium
You would be able to use your Hercules on AT&T but if the fast data you're referring to is 4G LTE, then no, you won't get that because the Hercules doesn't have the hardware needed to support it. You would get HSPA+ though.

No. You could turn off 4G and get EDGE/2G though.
On Verizon phones you can turn off 4g to only use 3g why would it not be the same

T-Mobile's 3G/4G networks run on the same bands so you can't block something on one band and only let the other thing work. I guess Verizon has different bands for 3G/4G.

I hope i'm not hijacking here but I have a similar question. I'm in an at&t lte market and was considering using my t989 with at&t via straightalk. Would I be better off to sell my phone and get a "true" at&t phone that does LTE?

If you use Straight Talk, then no matter what phone you use, you won't get LTE so it doesn't matter if you use a T989 or an AT&T phone.
