[Q] Switch a GS3 from Sprint? - Verizon Samsung Galaxy S III

I have four Sprint devices [two are GS3s] that I'd like to use on Verizon.
Can anyone tell me if it's possible to do something like that?
Verizon says that I can't use a Sprint device, but is it possible to flash something that will make it look like a Verizon device?
Thanks- I need to know whether to try to sell these phones or not.

Don't quote me on this, but I thought Sprint devices had integrated sim cards, only accessible via mods?
Assuming I'm wrong, you'd first need to check that the radio on the sprint variants supports any of Verizon's bandwidths. From there I'm not sure. Maybe flash a Verizon ROM and test? I'll do some research when I get home and let you know if I find anything useful.

Alright, did some reading. From what I can tell, the Sprint GS3 will have limited connectivity at best. The reason being that the radios do not in fact support the same bandwidths.
Verizon's S3 supports:
LTE 750
CDMA 850 / 1900
GSM 850 / 900 / 1800 / 1900
Sprint's S3 supports:
LTE 1900
CDMA 800 / 850 / 1900
US Cellular version adds CDMA 1700, LTE 700/850/1700
Verizon operates on LTE at 750 (mhz?) only, so that's a definite no-go on the LTE. As far as the CMDA 850 matching up - you might get some connectivity, such as voice, maybe 1x data/3g data, but I don't really know enough about the topic to speak with any certainty.
Hope this helps.

You can't anyway because Sprint and Verizon phones are locked because of cdma regulations or something like that.

My Verizon Note 2 is unlocked factory. T mobile sim cards work fine, I've tested it, just no data because the bandwidths aren't supported by the radio.

That's different. Note 2 is hardware unlocked so that you can switch to any carrier or use any rom worldwide thanks to your root method. Not the same for the GSIII. In Adam Outler's first Casual method for Note 2, he has a video explaining just how far unlocked the phone is and what you can flash since the hardware (as in the insides) is unchanged worldwide.

Obviously. Not disputing that - in fact I was more or less observing it. He said that CDMA phones are locked or "something like that" . That statement could be misleading to some, indicating that ALL CDMA phones are locked due to "regulations", when I know for a fact they are not.

They're locked in a way that makes it to where you cannot switch to Sprint if you're using a Verizon phone and voice versa. So they are in fact locked. Not gsm locked though. Cdma phones are locked. Our phones are gsm capable.

AT&T One X & MVNOs

I'm thinking of canceling my account with AT&T and using straight talk or a different MVNO but I have a few questions.
Will I still get AT&T updates? If not, will using straight talk prevent me from using any AT&T based roms or mods?
Will I lose LTE support? I don't have LTE in my area yet but it's supposed to be here in 2013.
Is anyone using a MVNO with their AT&T One X? If so, how's everything working? What's the best one to use?
I'll probably lose my warranty through AT&T but will HTC still cover the phone?

1) I don't think you'll get OTA updates, but I could be wrong. And obviously you can use AT&T roms, they're built for the phone.
2) Obviously, unless the MNVO you are changing to is allowed to use LTE, which is unlikely.
3) Using T-Mobile so don't know.
4) Yes they will.

No AT&T update, but you'll be able to use it with any ROM (as long as it doesn't require a SIM unlock, which you will have to do yourself).
You will get LTE support if the MVNO is an AT&T reseller and has LTE in your area. Though, afaik, there isn't any MVNO that offers LTE, maybe HSPA+. You can try Straighttalk or H2OWireless.
If you've been paying monthly for AT&T mobile warranty, then yes you will lose that, but HTC will still cover the phone for the limited period.

Probably a dumb question. Vzw sg3 on other USA carrier?

Looking at getting off Verizon, do not want to get another contract.
What is the status of our phone working on hspa? I've read in the development forum that in parts of Europe it gets hspa speeds as well as 3g so it's a Verizon thing?
Am rooted, unlocked yadda yadda running paranoid android rom.
Thx all.

Sell your phone for $300+, get a new one on your new carrier for less. Why keep it?

Thanks, but I am looking to set up on a prepaid service more or less. Guess I should have mentioned that in the op.

Won't work on US HSPA. There is a bounty thread in the forum trying to get it to work. Get another phone as other poster recommended. Will get EVDO speed. My other Rezound is Global on TMobile get EVDO only. Everything else will work tho.

AIO Question

My Nexus will be here tomorrow and I'm wanting to sign up with AIO's $60 plan. On their site it is asking for an IMEI. My concern is that the new Nexus IMEI may not be compatible with their 4g network. Has anyone else had success with AIO? I don't want to be stuck on 3g. Should I be seeking an IMEI from another device as a work-around? If so, what device, and where? My current phone is a 1st gen HTC Evo with sprint. Any help and advice is much appreciated!
Ive been wondering the same thing also.

They're using AT&T's network, I'm on it right now and get HSPA, HSPA+, and LTE. Works 100% fine. Used the same SIM card on my nexus 4 and had great service.

I've also wondered if AIO's LTE (AT&T) will work on the N5. So you have the N5 and it is working no problem? How are the speeds on LTE and HSPA+ (yes i know they throttle, just wondering how it feels)??

Unfortunately i don't have have a Sim to swap. I'm wondering if I order one using the IMEI from the new Nexus 5 will I be able to access 4g? Or will I be bumped to 3g because the Nexus 5 does not show up in their system?
Using Aio SIM from my N4 with not so good reception where I live and getting decent speed.
FYI, the N4 wasn't in their system either and needed the EMEI to activate.
Activating a nexus 5 on aio will be a cake walk. Nothing like the problems people over on sprint are having.

CDMA S3. End up being a paper weight??

Hi guys.
So i was given an cdma S3 as a present.
Now I do not know what network it belongs to.
Is there a way I can
a) Find out if its verizon or sprint?
b) Unlock it ?
c) wild question.... Can it be changed to GSM
Thanks
To find out the carrier that it belongs to: Settings - About Phone - Model Number. Go to Google and then type in the model number ... Voila! You cannot switch to GSM.

You can use a CDMA S3 on GSM networks. I am using one right now. If you pop your GSM SIM card in the phone, you will have service to make calls and text. Getting data is a bit trickier.

Is there really no sim card under the battery on the Sprint S3? I wasn't aware of that but clearly so since I don't own one.

From what I've read, Sprint does not use Sim cards. I could be wrong though.

The lte sim card is built in, under the center mid cover. Unfortunately, I have never tried to rrplace one with a prepaid.
I can, and have, flashed them to boost mobile and page plus. Talk and text is easy using wifi to update the profile, but data better than 1x is trickier, and requires a "friend".

If the phone doesn't have it you can't make it have it. You cannot unlock bands that are not there.

Why do you keep saying that. The phone has it. The specs says it does. Try googling unlock bands there are a couple I found on xda. One was for nexus n the other OE was for opo. The D850 is a little different because of art n I wanted something meant for this particular phone

Because 1 phone can doesn't mean others can... The G3 is not the same as a OPO or a nexus. The reason why some can is the band is locked out in software but is available in hardware. Remember bands rely on the actual hardware of the device. With the D850 if it doesn't have the band it won't ever have the band. And non of the bands are software locked to my knowledge. But if they are there's no way around it at this time.
If the D850 does indeed have lte band 1800 then it could be an issue with your APN or your carrier is using a different lte band.

Thank you so much. The phone has the band I'm sure I've checked multiple forums for the specs. So the band is there. I've checked with the APN which are also right. The ISP uses 1800 and the note 3 n9005 works great. It's just this phone something is wrong and I want to know what.

Theres been a few posts on Band 1800 with the D850 and it doesnt seem to work. So I doubt there's a chance of it working.
Please share those links with me. Why doyou think that is the case?

Just google it there's several posts about it. Because if that band is actually there hardware wise it is being locked by the modem and in which no one has a way around that.
