i wait your response. Thanks .

Or flash it to Virgin Mobile,Cricket or Boost?

The Sprint Galaxy S3 works only in CDMA networks... Not GSM.

Yeah someone definitively needs to post a tutorial i will donate $10 for tutorial.

Head over to usgalaxys3.com. The owner of that site has already posted instructions to flash it to Cricket.
I'm in no way affiliated with that site, just sharing where I saw the instructions.

The radio hardware matters, it has to be compatible with 1900 mhz Sprint PCS band. But the other things like GPU don't matter. lol

Virgin uses Sprint towers so band is the same.

Anyone know how to flash Sprint GS3 to Virgin? Or will Epic Touch method work with GS3?

Bottomline - You cannot use GSM phone on a CDMA network unless it is a global phone and supports both GSM and CDMA as well as the frequencies of the carrier you intend to use.

That is an obvious spam post. Please people, there are no exceptions... you CANNOT take a Sprint or Verizon phone and unlock it to be used on ANY service that is GSM or uses a SIM card. Period. The unlock sites will just take your money. World band phones will already be unlocked for use on European GSM networks most of the time so no unlock code is needed overseas.

You can flash it to another carrier though.

Not if the carrier is GSM or uses a SIM card. There is no possibility. Whatsoever. And unless you know a network level technician on verizon, you are limited to the smaller regional carriers and prepaid services to flash a Sprint phone. And vice versa for a Verizon phone. They will not connect a phone that does not already have its ESN already in its system.

Its common knowledge about gsm and cdma,if you dont know what these are then you have no business flashing carriers.
Sprint phones can be flashed to almost all prepaid carriers,overseas cdma is less common however there are ways out there to even flash cdma phone to their carriers.My father in Ukraine had his Epic 4g flashed to a carrier that uses sim cards,so there are ways even overseas.I think some overseas carriers use both cdma and gsm.

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.

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.

Lets Make it happen, Any model Galaxy3 on any network?

Ok ima try to keep it as short and simple as i can. I have a stock T-999 s3 tweaked to perfection running of Net-10 prepaid with the bring your own sim. Not only that I have it network unlocked so no matter what sim i place in weather its AT&T, t-Mobile, straight talk ect. i have service, each service i can critique to its best functions. Now heres my point. I also have a US Cellular galaxy S3 , rooted, and no matter what i do or try i cannot get this specific model to run a gsm provider via sim card. Im no wiz, but i get the idea, and my idea is to take this phone that is not supposed to operate on gsm carriers and make it operate. A recent example of success doing so was with my Droid Razr Maxx HD, i was able to successfully root the phone but as you all know verizon does not support us gsm carriers within the united states , or even on their network for that matter they block it. however after flashing a different modem, i am currently running t-mobile with great service! So any talk of "its impossible" i dont need, negitivity is not needed. i am fresh to this stuff but it fascinates me. cutting to the chase, what needs to be done to this sgs3 model #SCH-R530U to make it operate and function on a gsm carrier within the United states. Hacking Manipulating and tricking is all welcome that what were all about. Ive tried several things changing to global mode, gsm only,, faking gps positions to outside the u.s. and apn settings among countless hours beyond and im at a loss.. please im open to ideas and suggestions hopefully one day we make every model capable as nevery other

I believe the issue you are facing is because that particular S3 does not contain the necessary GSM radio chip needed to use those networks.
According to this (and its a wiki so it could be wrong):
http://en.m.wikipedia.org/wiki/Samsung_Galaxy_S_III
That S3 does not have any GSM bands for 2G or 3G.
However, once T-Mobile launches its 4G LTE on the AWS band, it should work...assuming the 4G network is both voice & data over LTE AWS.
The RAZR does work cause it does have the necessary 2G/3G GSM radio chip.

Simply put, the Verizon galaxy s3 is the only variant that has both CDMA and GSM bands. So if you wanted to do what you're saying, it would be most possible with the Verizon variant.
But for what you want to do, you'll need a world phone. And I believe the Verizon s3 is a world phone. Just gotta "hack" the GSM bands. Since they aren't active by default. But your T-Mobile att s3 will never work on CDMA. Also not lte will most likely not work on other carriers.

T-Mobile LTE working with unlocked SIII

Just wanted to let you guys know that LTE works beautifully on an unlocked ATT SIII.

so what if we flash an att rom that takes advantage of the lte radio in the phone (if we truly have one in the tmo version)

Now i am not sure on that. Maybe you should try

Gotta be worth a shot:thumbup:

identical hardware... it was just an idea. nobody can get the lte radio myth straight, so idk what to believe.

Yes it can be done but i have had bad experiences with radios causing serious OS issues. If someone had an S III to test with that would be great.

If you flash a att radio on a tmobile phone, You might be dealing with a serious brick.

I'm confused as to why this is up and getting attention lol? I might just be brain farting but, the person posts about his AT&T phone, with at&t bands (LTE) that they work on LTE??? I'm confused as to why this is news? Enlighten me maybe...

April Fools with a bricked S3! Don't know if I should laugh or cry...

Think the OP was just stating that his ATT S3 is working on TMO's LTE network...
The ATT has different hardware than the TMO S3...its not the radio software thats the issue...its the lack of a LTE antennae on the T-999
I believe the latest software update that tmo rolled out took out the LTE software that was in previous builds

While I don't thing we will get lte on our phones the thought of the hardware being different is hard to swallow. One of Samsung's deal with the s3 was hardware unity. With this they have one plant, one run to manufactur phones and when a carrier need a stock of phone all that was needed was software. This idea of a different model just for tmobile is hard for me to believe.
Once again I still don't see lte comung for us, so please don't assume I am giving any hope to get it

The Tmobile S3 has the exact same hardware as all the other US carriers including the antenna and modem, Tmobile just decided to use different lte bands. They will not enable the lte on the Tmobile S3.

If ATT S3 LTE can work on TMOB LTE network and T999 with same chip as ATT version.
sounds like TMOB trying to prevent S3 user to pull down they trial run LTE network.
and also prevent those people not in those trial site switch over other carrier.

I thought this was confirm a long time ago that the tmobile s3 doesnt support lte, As of an unlock att s3 to work on tmobile lte may be possible. if that the case It will be better off to sale or trade your tmobile s3 with an att version of it and you will have a s3 with lte

There will be a new s3 lte version of this phone at the end of this month...the current s3 is not the same as the att one so we will not have lte...

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.

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.
