Phone on different network

I have the nexus,obviously, and would like to know if I can use the Verizon version on a different network

Nope. CDMA phones are locked and there's no good way to unlock them.

Nope. If you buy the Verizon one you're stuck. Theres a small glimmer of hope that you could reflash it to another regional CDMA carrier, but even that's a long-shot.

short answer, no
long answer, yes
Anything can be done with enough will power. But practically speaking, no you cant.
I know a guy who got his CDMA EVO 3D working on ATT's GSM network. And I flashed my Sprint only EVO 3D to connect to Verizon. So yes these things are possible, but I wouldnt bother if I were you. If you want to use your VZW Nexus on a GSM network, then why didnt you just get a contract and GSM phone on whichever Network you wanted? If you want to flash to Sprint, Why? Verizon is much better, I just came from Sprint so believe me when I say Sprint has some ****ty service right now. Too many upgrades going on.

Is there any LTE enabling hacks for T999? T-Mobile USA

I've read YES, I've read NO...?
Is there anyway to enable and use LTE on the T999 on T-Mobile?

Try going to Canada that's the only place that uses the same LTE frequency that T-Mobile will be using. Might work like the Nexus 4

The T-Mobile network does not have LTE rolled out yet, but the hardware does support LTE.
I'm sure the way to enable LTE will include flashing a new radio, though I'm not aware of any that will enable LTE without bricking the phone or killing data communication on the SGH-T999 specifically.
Edit: So far it would seem that the LTE supposedly in this phone doesn't run on the same frequency spectrum that T-Mobile plans to use for LTE.

@woostar88
I've spent probably two hours in the last few days purely searching and reading whatever specs I can grab, including for FCC ID A3LSGHT999. Every time I'm sure, something knocks me back down to unsure status. It's especially confusing when Samsung, the maker of the phone and the Snapdragon platform it runs on, says it does support LTE - then T-Mobile comes in and says nope (and that it's based on the Snapdragon MSM8260 instead? wtf?).
While they are contradicting their hardware vendor, they have support reps saying both yes and no. No wonder nobody knows anything,
but I'm determined now.
Unfortunately for me I'm not as privy as I should be to the massive amount of terminology and mobile spectrum standards that have been bestowed upon us, but a little more research should bring me up to speed.
My answer until I have a better one is that yes it very much is an MSM8960, and yes, it does support LTE.
No, the LTE this hardware supposedly supports is not using the same frequency spectrum that T-Mobile in the US eventually will (like snoopy1e11 said in this thread).

Please post questions in Q&A

Of course T-Mobile says it doesn't support LTE. They'll do what they did with the Vibrant. Sell a boat load of them and then release a slightly updated version with full LTE radio. I trust Samsung before TMO anyday.

For all of you saying it's going to support lte, and that our chip is the same as att, answer me this:
Why can we not unlock our device, place a att SIM card into it, register it on att network, and access lte on att network? If all our devices have that same chip that supports lte as you all are claiming, why can't we do this?

Your first three points have no influence from the chip design; The (in)ability to unlock a device is controlled by software, the (in)ability to use a SIM card from another provider (which is generally the exact same hardware) is controlled by software, and the (in)ability to register it to another provider's network is controlled by software, as long as the hardware radio chipset can speak the network's frequency and mobile protocol.
I don't know off-hand why it won't connect to AT&T's LTE. I'm also not an electronics expert but I can imagine that these chipsets can be controlled with firmware to restrict the frequencies the radio may generate or receive, effectively locking it to a provided number of frequencies assigned to the mobile operator.

100% agreed.
The best arguments for and against have already been made. All i see this doing is mirroring all other threads on the same topic. Tempers may flare, infractions might be made, all because no one wants to be wrong and cant wait a year or two when the subject actually becomes relavent.
Search and read. Hint: general section.
It can be disabled on both the hw and sw side. In the end it doesn't matter because the T999 was never certified/cleared by the FCC for LTE. So they'd either have to go back through the process or be fined for breaking the law.
I'm convinced it won't happen, but to each his own opinion.

The only reason that the tmobile t999 has any LTE files in it is because all the carriers have the same base rom then stack their crap on top of it! I know how to read code and if you break down most of the apps in the phone they will have provisions for all carriers, not just tmobile. Tmobile doesnt even have LTE towers yet so the answer is still no

In a few select places, T-Mo has LTE. In fact, they'll be sharing towers with Verizon.
But, the true answer to whether or not the T999 can get LTE or not is, gram crackers and apple juice. Yep.

Yes, I know, as everyone else, that one is GSM and another is CDMA.
But, fact is that T-Mobile are Verizon are swapping frequencies with one another. What I'm confused about is if this means they're literally using the same towers or if each carrier has so many licenses of certain frequencies and now they're giving up some of those licenses.
I'm confused.
But, what I do know is that:
1. The two are swapping frequencies with one another.
2.Verizon does use GSM LTE.
3. Gram crackers and apple juice determine whether or not the T999 can get LTE.

Its simply a spectrum swap. They're not using each others towers. At least not for anything other than roaming services. Tmobile and Verizon will both be able to use this to provide better and more widely available service and coverage to more people. But they will be using tbe newly aquired spectrum on their own towers and equipment. Not each others.
Its one if the conditions Verizon agreed to for FCC approval. Tmobile swaps a small bit of their licensed spectum along with "cash and other concessions" in exchange.
Good for Verizon, good for Tmobile, good for consumers is the reason the FCC made it a condition. Thats how I understand it anyway.

So, then it's a matter of each carrier having so many licenses to certain spectrums... Like I have 600,000 licenses of something and you have 700,000 of another and we give each other 300,000? Is that kind of what's going on here?

Sort of, but Im not sure it works entirely like that.
I do know that Tmobile received enough to support approximately 60 million new customers in 15 of the top 25 markets, while Verizon received enough to support 22 million, plus cash and such.
I don't really know how the licensing works, but I don't think it goes by the number of users or anything like that, but by frequency ranges. Id imagine theres more to it than just you give me x and I give you y though.

Such hostility in here over a easy to answer question.
In short:
No there is not a way to enable it, as it has not been implemented by t mo just yet.
Yes it will require a radio update.
Yes the s3 (even the t mo version) is LTE capable.
Was that it or did I miss another question?

Tmobile note 2 on AT&T?

My wife and I are considering taking our tmobile phones over to AT&T. There both unlocked... Note 2 & sg3. Question I have is would I have to flash AT&T modems and roms to be able to fully utilize the new network? Just don't want to end up with bricks. AT&T already told me both devices unlocked will work fine on the network.

Wat I'm asking is if I can utilize the lte on the t-889 if I put it on AT&T? I found a bunch of threads with mixed responses.

I dunno about that as many said everything works but LTE. I have also read a few that says they have LTE enabled. That's what's confusing. I may go to AT&T tomorrow and have them test a sim before I decide to switch. I assume if I change to AT&T apn ill get better 4g speed at least. The limitation your speaking to its a locked radio for the t-889 that prevents LTE from being enabled currently.

I can't quickly tell, but if it has LTE support on band 17 (700MHz) then it will work. It's a T-Mobile phone so it has support on band 4 which AT&T only uses for a very small part of its LTE network.
Like you said the radio it comes with might be locked to not allow LTE. If you can flash an AT&T radio without issue then you'd be able to see if it works.
If I were to guess I'd say it would have the right band since it's basically the same phone that AT&T sells.

Does it at least get hspa+ and 3G? I can wait for lte.

If you are switching over you should just sell those two phones you have and just buy new ones since its new activation Im sure you can get a good price on the phones

From what I understand its not hardware, it's because of a radio limitation currently. Lte isn't enabled yet on the t-889. That's why I asked if I could flash a AT&T radio. As long as I get 4g and 3G ill switch. The whole point was to save $$ on buying new devices.

T-Mobile scam exposed "galaxy s3 not compatible with LTE"

T-mobile is pretty evil in my opinion. The galaxy s3 should get the liability to be able to connect to LTE on their network. It isn't fair that they removed LTE capability via a software update. Proof; appleandroidguide on YouTube, watch the first video and you will see

I buy my phones based on what they can do the day I buy them, not what may happen in the future. It would be nice to have the LTE option but I never really expected it despite the promises made by sales staff and customer service. I will go buy a full blown LTE phone if I feel the need.

Sorry but your wrong, the only phone T-Mobile has for sale that has the LTE capabilities is the Note II because its exactly the same as the AT&T version. If you open it up you will find out that the phone may have an LTE radio but no antenna, like the Nexus 4. And really you should but your phone on what you can do now, not down the road.

You gotta ask yourself... Do you really need it?
And if you do ( for reasons such as deeper penetration into buildings so you actually get 4g where you live or work or whatever..not just for faster 4g) then sell your s3 and buy an lte s3 or s4.
Your s3 was launched a year ago..that's a long time in technology. Get over it.
Its like buying a new car then complaining a year later that the newer model has more horsepower and better mpg.

Okay how is it a scam? If you bought the phone when it came out(1yr ago) Tmobile wasn't even hinting at lte. You bought the phone with an understanding of what it was capable of. Most people aren't xda people. They don't go on forums and check out detailed specs sheets and breakdowns inquiring about possibilities of a phones hardware. Sometimes I think its a curse to have such knowledge as we know more than the Tmobile reps or any carrier reps do. The xda community is a minority. They aren't going to change anything for us. They know if people want stuff bad enough they will either leave, pay , or stay where they are at. Tmobile will not bend for you or anyone. You know how hard it was for me to get credit from them for something they did (680++$$) ??? Over a week on the phone.

Just Ranting but here !!
Come on guys Really ? Technogoloy changes so fast these days no and keep up unless you have deep pockets filled with money and still while your standing there while to pay for it a something newer faster nicer sweeter will come a few days after you buy it. This is the name of technology sales my friends. I get HSDPA+ . Sprint pushes out Samsung S3 to people telling them “ Oh it 4G and LTE soon” in the NYC area but out side of the 2-5 miles you may get 3G that’s is it sometimes and another times crap. These carriers for there not for you but for your $$$$. So that’s why I buy my T-mobile phone based on what they can do and for how long. The very fact that you can pull out the sim card and just drop it in a other T-mobile just is a plus. Is this not why we are here because after we Root our phone and we come here for what they don’t give us?

You may enjoy the speed now but think about internetwork operability and the plans to launch voice over LTE via VoIP-based technology and its a no brainer that its something you want.
Keep in mind, it may take entirely new radio technology to take advantage of VoLTE so buying an LTE phone may already be outdated by this year which, besides economic factors, is why I'm waiting to see what happens in 3Q and 4Q

If I remember correctly, the T999 gs3 doesn't even have an LTE chip in the phone. That's what tmobile is releasing the T999L that INCLUDES the LTE radio. The OP is an idiot, and if idiots dont wanna take the time to research and learn about stuff, then they deserve every bad thing that happens.

It does have the lte chip but it isn't activated and won't be because they went a different way with lte bands.

I guess I don't understand what the fuss is. When this phone came out for Tmo LTE was not even confirmed. Knowing this, and the fact that absolutely nothing has changed in terms of what has been said about this phone from either Tmo or Samsung about this phone having lte capabilities, there is no scam. We can wish that it was built with the compatible hardware, but the bottom line is that things could be worse, we could be stuck on sprint...

where I would disagree is in your statement about nothing has changed. I too was told multiple times before buying the phone towards the end of the year that it was lte ready and would get it once it came out.

The phone has an LTE amplifier for 700mhz and 1700mhz bands but no modem is mentioned. I would be curious to see a teardown of the V model... Its supposed to be identical to T-Mobile from what I understand...

So it has the lte radio but not the correct one? I been reading different threads on this figuring out if i was gonna get one but don't know if i want to. What lte bands does TMobile use

No. GSM phones are incompatible with CDMA networks.

I have a stock sgh-m919 and I gave my imei to Verizon over the phone, they stated they could not use my phone on a prepaid plan, but I did not inquire about a contract plan. Visit a store and ask questions.
I realize Verizon is CDMA, but I have seen those radio ROMs somewhere to change the frequency of the radio. I think it would require more than that, perhaps even an imei change, I don't really know, I'm just going out on a limb here.
From what I understand Verizon does use the 700Mhz band like AT&T but they use a different portion of the band, the upper is what I read. Google 700Mhz LTE, I think that it will come up.
good luck, let me know how that turns out.
Also, my mother has a Iphone 4S on Verizon and although I don't really like apple products, I do know that it has a sim card slot, so that taken into consideration, perhaps there is hope.
