[Q] If i buy an ATT gs3 would i be able to use it on t-mobile

like the title says after i get it unlocked would it work just like a t-mobile gs3? or do they have different hardware

Different radios. It does not support AWS on T-Mobile.
Also use search next time.

There is a hack for the T-mobile Version So you can use it on At&t But I do not know of one for At&t. Here is the link to the directions on how to do that if you want to switch to t-mobile.

If they're in the refarmed area where they are using 1900MHz then yes it will work . But you're right, if they used search they would know this already.

Not true. If they live where they did the re farming to the 1900 frequency then it will get h+

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.

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.

Flashed Htc One ?

I am wondering if a sprint Htc One flashed to verizon would get as good of a signal and a verizon branded One?

Most likely not. Different carriers run on different frequencies.

.... That sounds wrong... Maybe their postpaid is different. From what I understand not only are the frequencies different version must sign off on every phone on their network...
After some research I've seen both sides being positive they are right. One constant though is that Verizon must sign off on every phone in their network. Perhaps their post paid works differently.... Or maybe I'm wrong

I used to run a Sprint HTC Touch Pro on the Verizon network.
I ported it over, but that was years ago.
Both 1x voice and evdo/3g worked fine.
Was a bit trickier to get 3g then it was the 1x but lte certainly won't work on a Sprint on Verizon.
I certainly wouldn't go buy one from Sprint though planning on getting the ESN to get passed by their checks.
That's all I will say about that aspect.

just because a phone is global doesn't mean it will work on all networks. there are too many possible bands to acct for. You would need several radios, which would eat battery.
"Global" phones will work on the most popular bands.
As far as LTE, there is not a chip that has all the US bands.

Using bad ESN HTC ONE on AT&T

So recently I came found pretty beaten up HTC ONE that is Verizon branded. I called and they said its a bad ESN that the previous owner didn't finish the payment. So I was wondering, (yes I looked through various threads and could not get to a final answer) if I use this phone with an AT&T sim, it will work right? Verizon HTC ONES are required to be GSM unlocked and ESN only matters to CDMA carriers and not GSM carriers. Thanks.

Are you asking the XDA community or are you telling us? I'm confused as to what you are getting across here. If you have an AT&T sim or know someone who does then pop the sim in and find out if it works... Did you call Verizon or AT&T and ask if they will activate it?

It is unlocked, so as long as it has the proper bands in it, it should work on AT&T. I'm not sure if it'll work with LTE or just 3G. No idea as I've never tried. I've also read that you have to update APN settings. AT&T may not "officially" let you use, like register it to your account because it wasn't an AT&T phone but if you can pop a SIM card in it you should be able to use it, as long as it works.

Wrong. You're thinking of T-Mobile
http://www.htc.com/us/smartphones/htc-one/#specs
The VZW variant HTC One includes the following GSM bands: UMTS/HSPA 1900/2100MHz and GSM/GPRS/EDGE 850/900/1800/1900MHz. These frequencies align with AT&T's services. T-Mobile uses AWS bands (which include 1700mhz) for their HSPA.

I might be wrong.. but all Verizon Phones are Sim-Locked for any USA carrier, you could however use the phone just fine in any out of the country carriers. but like i said i might be wrong which i often am

Don't waste your time. My thoughts were the same when I bought my Verizon One. I planned on using it with a GSM carrier. I had read that its hardware had the necessary bands and they probably are there but I can guarantee that they are at least being blocked somehow by Verizon (data-wise) . I only got 2G and this is from actual hands-on experience with SIM cards from both at&t and T-Mobile. Voice worked great but data was horrible.

They ARE sim unlocked but crafty Verizon somehow managed to block high speed data even though they are SIM unlocked. I'm sure this can be fixed somehow but nobody seems to be that interested in getting this taken care of. Fortunately for me I was able to get a very good deal on my Verizon plan so I kept it for myself and my family is still on my original T Mobile plan.

Is it a Verizon One? Did you flash anything to turn off the speed cap?

I have a Verizon HTC one and I have a Straight talk ATT Micro sim card. ATT has great coverage in my area. You will only get Edge data. But text and calls will work. Reason is because you need both the 850Mhz and 1900Mhz band for ATT. I believe you will get HSPA on a Tmobile sim if Tmobile has the 1900 band rolled out in your area.
I have a droid DNA and with the ATT Sim card in the DNA I get HSPA speeds but only edge speeds on the One. The DNA has more bands available where as the HTC one from Verizon has the 800/1900 gsm bands. Since most of ATT uses 850Mhz, you can't just have one band and expect 3g/4g you need both.

Also just tried a tmobile straight talk SIM card in my Verizon one and still only get edge. To get better speeds you would have to get a different phone like the DNA, gs4, or an actual att or tmobile phone.

It's only missing Band 5, both models have bands 4, 2, and 17, which are the primary US LTE bands anyway (outside of Verizon's Band 13 that is).
While technically the T-Mobile version is missing Band 30, the AT&T version is missing Band 30 as well.

The T-Mobile one hasn't been rooted yet, though it apparently has an unlocked bootloader. The AT&T model has been rooted, but it appears the bootloader is locked down. Doesn't that suck?

Ya it does. the pre release t mobile phones were able to be rooted but the patched it already for the phone that are shipping now.
Unlocking the bootloader is harder then rooting for the most part. What im interested in is if the qi charging back from europe are working on the tmobile lg g3....they are not on the att g3. Can you test this!? that would be awesome
