It can be unlocked to work on Tmobile in some markets depending on what frequencies are available where you live. I am currently using my SPH-L720 on tmobile in PHX AZ . Some users have reported Net10 working and others ATT but I have never investigated this. If you want to see how it works I have compiled a guide that outlines the steps I took to make it work on Tmobile. http://forum.xda-developers.com/showthread.php?t=2530610 Also look in the International SIM unlock thread in Development and the GSM data thread in general for further tips.
Also I'm sure it can be flashed to boost you just need the PRL file to flash. Check out this thread.

Flashing to Verizon..

Is it possible to flash the sprint nexus 4g to Verizon? If so, how?
Thanks
The short and simple answer is no. If you want the long detailed version look around xda as this gets asked a lot in other cdma phone sections...

Oh ok thanks. I figured it could be possible since the verizon iPhone was able to flash to sprint. I guess the nexus is different or something.
i would imagine using tools there available online you could in theory get it going on verizon and maybe even get 3g but 4g wouldnt work for sure

When did this happen? You might be mistaken

I have a verizon prl flashed. It allows my nexus to roam on the verizon network at all times. It increased my dl speeds from 300k to 2mb per second.
You still need sprint service though.

Could you post how you did that? I would like increased 3G speed and coverage. 4G is fine in coverage areas for me. 3.5-5 down avg

Nope..it's highly possible ..check YouTube and eBay. People even got step by step and so on. So I know it's possible.
I was hoping to do the same thing. Technically it seems like the Sprint ones should be possible.
I poked around the forums trying to find a general answer why this wasn't possible but didn't find any real concrete answer. Can anyone explain why it's not possible or point me to a post that does?
Thanks
Possible, yes. Legal? Not so much.

The fact that its illegal is why your not going to find a how-to on xda.

Why would it be illegal?
Root your phone and then download roam control.

I dont think you understand what the OP is trying to do. He doesn't want to roam on Verizon, he wants to get a Verizon plan and activate his phone on Verizon. That requires falsifying your IMEI and no you cant do that with an app from the market.

The hardest part would be getting VZW to add the devices IMEI into their database, impossible, no, but very difficult.

Help switch USCC gs3 to Verizon gs3

So I US Cellular is done in Chicago and I refuse to purchase another phone if I can change over with my current one.

Looks like you're in the wrong section. This is for the international GS 3 rather than any us variant so any help probably will either be a. Harmful to the device or b. Not helpful at all

Sprint Galaxy s4 on Tmobile.

I never had a gsm phone so I dont know alot about world phones. On sprints community foruma there is much debate if the gs4 is a world phone. I see a sim slot my guess that it is. Anyway if I were to switch to tmobile, can this phone be used or is it completely impossible? Other countries use gsm networks only so being a world phone I would assume that it can be used with US gsm networks. Thanks.

It is a world phone but it is locked to Sprint only you can call sprint and have it unlocked for international and sprint simcards only no domestic Sims like from t-mobile and AT&T.

Okay did some research and youre correct. Invalid sim pops up when a local sim is inserted. Lets say I flash the google edition rom stock rooted. Now I know it will mess up all radio with cdma but will this bypass or does sprint have a hardware lock on the device?

Yes, it will work on tmobile for text and call when you unlocked it. For data, you need to change the apn setting to epc.tmobile.com. I am sure that you will get EDGE but not sure about 3g/4g or LTE.

That is not correct. It will work if you unlocked it. You will only get EDGE data for the time being in the US.

You can't do it, it is impossible. Sprint has US carriers blocked and there is no method to unlock to use a Sprint phone on Tmobile. So here is the steps to follow: List your Sprint phone on Ebay or Craigslist, Sell it, go buy a Tmobile S4, enjoy.
2nd try

Im having difficulties rooting the S4. When I check it says its not rooted properly. Im still on MF9 and have no clue how to get it to MDC/MDL baseband. Any help? And how would you change the apn settings?

There seems to be a very dismissive attitude in this thread.
I have a Sprint HTC One and I can easily throw a T-Mobile SIM in there and get full service (sans LTE) with T-Mobile. The HSPA+ is faster than the Sprint 3G.
So while I do not have personal experience with the S4 in this fashion, I do not see why it would not be possible to get it unlocked and used on T-Mobile. (Unless Samsung/Sprint are blocking it for whatever reason)

Pisses me off free unlock method

I did the free unlock method and pop in a prepaid t- mobile micro Sim card and wile it don't prompt for an unlock code it surely don't/won't connect to internet or even show E ,4G,4G LTE at all.I have to switch to stock rooted MDL just to use the service mode *#0011# and have tried just about everything with the exception of using fastgsm.com on the account of not owning a computer. I even tried sha256 back on and inserted the T-Mobile card and enter *#0011# to repeat the process. Still no unlock code prompt either way and no real service either way.anybody can reply/pm me

Tmobile has poor coverage. Good prices, but poor coverage.
That's not the reason. OP is using an AT&T S4. Any time you use an AT&T phone on T-Mobile, all you get is 2G.

True, I'd be with them if the coverage was better.
Hmm Try to disable mobile data and reenable it . make sure your APN settings are correct. If not then you may need efs repair...
You can also try the option NV Rebuild

What?
Like I said before, any time you bring an AT&T phone to T-Mobile, all you get is 2g data. Anything you try to get better will not work. If you want better either buy a T-Mobile device or get an international version of the device. Best option in this case is to sell the AT&T phone and use that money towards a new device.

I had issues with Tmobile at my house, just sitting outside on the deck... 1 bar of EDGE. Phone calls would work 25% of the time. Data would work, but rarely.
[soapbox]
As a side note... I HATE the current state of the cell phone industry in the USA. All phones should be unlocked, penta band, and sold directly from the manufacturer. Issues like this would never come up and the prices would stay down to be competitive.

While that is very true, providers/manufacturers don't want competition. They want to own everything.

Not hardly. With AWS you can unlock all the bands so att phones can get T-Mobiles lte and att lte. Noone listens because its not true. A ton of people have reported about this. Read up on it first.

From what I can tell, it looks like the process didn't flash correctly. Restore your backup (assuming you made one) and try again. It could have been a bad download. Try re-downloading the needed files. If that still fails, try another USB port and wire if necessary. If all else fails, t-mobile sucks horribly in your area.

I have a extra tmo s4 and I was wondering if I were to unlock and flash an att rom n apn'z would I still get lte speed.
And does a bad tmo imei get blocked on att too?
Sent from my SGH-M919 using XDA Premium 4 mobile app
It will work as long as the imei isn't affected on the att side. If device was reported lost or stolen it will be blocked on both carriers I believe. If just unpaid on tmobile it sometimes works but I'm not for certain. Att Roms will work but you'll have to flash a T-Mobile or i9505 kernel I believe as most att custom Roms have loki kernels.

Thanks Febby. I'm glad u reminded me about the kernel. Probably would of bricked.
Its just an unpaid tmo phone from a family plan gone wrong.
I suppose I could use a GE rom too I hope.
