Unfortunately, can't be done as Verizon uses CDMA and ATT uses GSM. Means radios are completely different.

As stated above, Verizon and att use two entirely different networks. The radio hardware is different. Unless the droid dna is a gsm phone that should not be possible.

That phone is also GSM capable. At that point it's all a matter of the APN settings. It can not be done with the S3 on any carrier (swapping from CDMA to GSM)

I think you can get the Verizon S3 to work on AT&T (calls/text/edge data). I know you can do that on T-Mobile. But you won't be able to get the AT&T S3 to work on Verizon for two reasons;
1) The radio would need to be hacked to enable the CDMA radio, and the information needed to hack the radio is not available. The US variants all received the same radio chip, just some of the frequencies are turned off. For instance, the AT&T S3 wasn't able to get the t-mobile AWS band working until the guy working for t-mobile released some radio files. The AT&T/T-Mo S3s have the CDMA radio, but it's not enabled
2) Verizon won't allow the phone on the network, as the IMEI is not registered on their network. This is probably the most important reason. You would need to spoof the IMEI from another verizon phone, which is not something that can be discussed here.
You are better off switching with someone who has a Verizon S3, that wants an AT&T S3.

It will work with T-Mobile because it's a GSM network. The radio can't be hacked. It's a limitation of the hardware itself. It's 2 completely different pieces of hardware.
The sim card on Verizon phones is ONLY used to access Verizon's LTE, without that simcard you'd have regular 4G only on a Verizon phone. That sim card/or phones acts in no way possible as GSM accessible.
So no it will NEVER work regardless of what you do.
And don't fall for ads on the internet about any Verizon,Sprint, or any CDMA phone to work on GSM networks.

This is not entirely true for all Verizon phones. The DNA, S4, Note 2, LG G2 (among others) are sim-unlocked out of the box, and will work with AT&T/T-Mobile (the note 2 requires some hacking in order to add the APN settings). Also, as I recall, if I took the sim card out of my GNex and DNA, I did not have service. It would only allow for emergency calls. No talk/text/2G/3G.
For the Galaxy Nexus, the phone is 100% guaranteed to not work on any GSM network.

Read the first sentence
"Only to get Verizon's LTE"
Unlocked phones work "globally"
Which means you'd get Voice and EDGE/3G at the most from other GSM networks, given you've provided the correct APNs. Locked phones, which carry that sim card for Verizon's LTE ONLY. Either way only a few phones will work. The rest are useless.

No. They use the same hardware. Msm8960. It should support GSM CDMA WCDMA LTE and Td-scdma. Almost all the network. It's mostly because of the lock of the radio/nv.
Remember, the op is asking if he can use an at&t galaxy s3 on Verizon. It's not going to work.

i can verify that i an running AT&T straight talk service on my sch-i535 (Verizon Galaxy s3)
I have had success using a Verizon sg3 mother board on att's network although I was only able to get 2g. What I did was rooted phone, ran region unlock app, next I let the phone sit for a day, then a did a factory reset from the phones menu not custom recovery. Then when going through the set up wizard it prompted me to insert sim card then it said it was not an approved sim and gave options to continue or finish, selected finish, said complete and about 3-5 mins after booting up I got signal bars and phone was working. Although the hardware used are different these are dual band phones.
Never give up keep trying

If we buy the Verizon version, unlocked, will it work on AT&T? Is this going to be an option, or just importing it from uk etc?
Could of swore i read somewhere that att's lte will work on a slightly different mhz that it won't be compatible with verizon's lte, someone correct me if im wrong.

The "AT&T" one, which at the moment is the same as the "world" version will NOT work on VZW.
As of now there are 2 models of the Galaxy Nexus: 1) CDMA/LTE (for Verizon in the USA) and 2) GSM/HSPA+ (for the rest of the world, yes including AT&T and T-mo in the USA).
As of now, there are no GSM/LTE versions (I'm assuming this is what you're looking for on AT&T). If you use the GN on AT&T, it will have HSPA+, but not LTE. And no, the VZW version will not be able to be unlocked and used with an AT&T LTE SIM card, because AT&T is only operating data on LTE, and you'd get no voice/text (assuming you somehow got the device unlocked to accept the SIM in the first place).
Unless Samsung/Google have some kinda curveball lined up to announce a 3rd model with GSM/LTE for AT&T, that will come in the future. As of now we're not aware of this model.

You are correct in saying the Verizon Galaxy Nexus will not work with an AT&T SIM. However, the reason you provided is incorrect. Currently, both AT&T and Verizon operate data only LTE networks. Neither provide LTE voice (Voice Over LTE aka VoLTE) but both plan to (Verizon in 2012 and AT&T in 2013). Whether or not the Galaxy Nexus can take advantage of VoLTE is another open question but it will be able to use CDMA voice either way.
The real reason your Galaxy Nexus will not work on the AT&T network is the LTE frequency bands are different as well as the obvious 2G and 3G CDMA/GSM incompatibilities. A Verizon Galaxy Nexus with the an AT&T SIM (assuming you can unlock the device) will never be able to find the AT&T network. Hopefully, future devices will offer software programmable radios that can be unlocked to interoperate on multiple bands. There are plans for some 43 LTE bands worldwide!!!
So I'm guessing that by the same token in Canada, if your with bell, getting the LTE version is pointless?

Thanks for a little more information, but I said just as much. Even if you somehow got it unlocked to accept a different LTE SIM card (don't think it'd ever happen), there are several reasons why the phone wouldn't work. Even if they did have the same LTE frequencies exactly (or you hacked it on), he wouldn't get any GSM functionality out of the VZW device.
Basically what I was trying to express is that the other things could theoretically be overcome with software/firmware hacks (VZW and ATT will operate in the same spectrum, just slightly different frequencies), whereas you can't ever overcome the fact that the CDMA does you no good on the AT&T network.
Overall I think the point has been made regardless...
dont forget sprint and other cdma carriers in US
I am going to switch to T-Mobile in 2 months so was wondering if it will work with T-Mobile's HSPA + Network.
AFAIK It won't, but the frequenceies are listed on both carrier's sites so you can have a look at that.
No.

Couldn't we just flash the t-mobile radio like with the t-mobile sgs2 and the skyrocket from at&t?
It should be possible. Check out the specs of the two: http://www.gsmarena.com/compare.php3?idPhone1=4804&idPhone2=4803
This is EXACTLY the same as Tmobile S2 and ATT S2 LTE: http://www.gsmarena.com/compare.php3?idPhone1=4129&idPhone2=4303
Some awesome dev needs to do some radio hacking to make the two phones interchangeable as they did for the S2/S2 LTE.

The CDMA and TDMA versions are different and not compatible. A sprint or Verizon model will not work on GSM networks due to the different protocols used. AFAIK no phone is universally portable amongst US carriers.
Verizon/Sprint/US Cellular phones are 100% different in terms of radio hardware and software.
It is possible the T-Mobile/AT&T ones will likely work together, but why? Also something to consider is the AT&T Note on T-Mobile gets HORRIBLE battery life.

You sure about this? Verizon model will have a sim card and has GSM support. Verizon will probably block T-Mobile and ATT with all of their GSM/devices.

The SIM card is for LTE. The only way to get 3G on a CDMA device would be through CDMA.

Not exactly true... After a "hack" to my VZW Moto Bionic and dropping in an ATT sim from a demo Galaxy Note, we got working H+ on the Bionic.
Even after hack, the Bionic doesn't appear to support T-Mobile's 1700mhz so I get EDGE only when I use the T-Mo SIM out of my Galaxy S2.
But I wont have a Verizon Galaxy S3 to play with to see how that works.

Interesting, have not heard of that one but I will take your word for it. Either way, most phones do not have AWS bands for T-Mobile unless they are T-Mobile phones.
Assuming the Verizon version has GSM 3G radios in it (what they call a "Global" phone) I don't see why even it could be flashed if someone could get the radio hacked.
For example, my current phone, the Droid 2 Global, normally runs on Verizon's CMDA bands. Being a global phone, it has GSM radios in it which can be activated if you get an unlock code from Verizon (not difficult).
Here's the catch- the baseband locks the phone so that it does not work on AT&T and T-Mobile's frequency bands! However, some clever hackers at TeamBlackHat were able to hack the baseband to allow it to work on US carriers as well.
tl;dr if the CDMA versions have GSM radios it should be feasible to make them work on AT&T and T-Mobile.

Until vzw goes to VoIP in the next few years the only thing the sim supports is 4g data. Because lte is a gsm based network, sim cards are needed. Nothing else in a Verizon phone used the sim so no you would not receive full service using a vzw sim. Not sure if you'd receive data or not but I'm betting no
Verizon uses CDMA for voice, and CDMA/LTE for data. Not only are the LTE frequencies incompatible, but CDMA is incompatible as well. So no, the Note 2 will not work AT ALL on Verizon.
Also to note, Verizon will only let you activate VERIZON BRANDED phones on their network. You can't buy unlocked phones and use them like a GSM carrier (AT&T, T-Mobile in the US) would. Sprint is the same way.

This does not exist on ANY Note 2 on earth. Possible with *SOME* other phones, but not any Samsungs, and definitely more trouble than it's worth. NONE will be LTE compatible though. 99% of the GSM compatible phones on Verizon are locked on only work internationally, and will not work AT ALL for the US.

Any new Verizon phones can work on any GSM HSPA+ network with some trickery or are unlocked out the box. Some phones work on At&T and T-mobile while others only work with carriers outside the U.S. YMMV.

Well one rather big difference of the Sprint S4 mini (SPH-L520) versus the international models (GT-I919X) is that it uses CDMA networks rather than GSM. I am not sure if you can use it on GSM networks with a sim card. I do, however, know that the Verizon version (SCH-I435) which is also CDMA can be unlocked and used on GSM networks. I used the app RegionLock Away from the play store (and here on xda) to unlock and it worked with an AT&T sim card.

sprint sph-l520 NOT a worldphone
I talked with the Sprint folks.
The Sprint variant has a sim tray that is just for the data sim (UICC card) not a GSM sim. And it is NOT a worldphone.
So even if you put a GSM sim in it, the radio is not looking for GSM towers (only CDMA).
But the Verizon version IS a world phone, which is why "wiisixtyfour" was able to unlock his.
That being said, since Samsung has made several versions that do have this capability, it seems possible that if someone modifies these things it could work:
-Modified sprint radio to receive GSM radio frequencies/signals (maybe copying the Verizon one?)
-Modified PRL to look for GSM towers
-Modified SIM tray communication to recognize not just DATA sims but GSM sims as well
I have no idea how to do any of these. But would love it if someone a lot smarter than me can take a stab at it. :cyclops:

I have no idea how to do any of these. But would love it if someone a lot smarter than me can take a stab at it. :cyclops:

Please do
SPH-L520 can run on GSM carrier!
Yes, this is what Sprint told me last summer. But it's incorrect. I have a Sprint S4 mini that works on both Sprint and a TMobile MVNO. Voice, text, data (in refarmed area). Unlocking GSM can be done!

I talked with the Sprint folks.
The Sprint variant has a sim tray that is just for the data sim (UICC card) not a GSM sim. And it is NOT a worldphone.
So even if you put a GSM sim in it, the radio is not looking for GSM towers (only CDMA).
But the Verizon version IS a world phone, which is why "wiisixtyfour" was able to unlock his.

avgtuhm, that's only true if you can explain how it was done and it can be replicated.
What does #0111*NETWORKCODE accomplish?
First off, my apologies if I am in error about GSM functioning on my phone.
I will explain what I've done with my Sprint S4 mini and maybe you/someone can tell what is happening. But this is why I thought GSM was/is working on my phone, until supermaxkato questioned this. (Note: I am not a developer.)
My S4 mini is active with Sprint. If I put a GSM SIM in it, of course it does nothing. Try to make a phone call and I get an automated message that it cannot be completed. But after doing the following, I can make calls, send texts, use mobile data.
I powered on with GSM SIM in phone. Entered #0111*NETWORKCODE for my phone in the dialer and hit call button. After this voice, text, data work. However, phone shows "Invalid SIM" in the notifications and the calls and texts come from my Sprint phone vs. the number associated with my GSM SIM. (I didn't realize this until testing last night.)
So did the code just make it so the SIM tray ignores the GSM SIM and functions on Sprint network? (again.. before entering the codes, no calling/texting/data worked with GSM SIM in the phone)
Same results on 2 activated Galaxy phones. Unsuccessful on non-activated S4 Mini.
I am not tech savvy but if anyone wants me to check something on my phone, I will try to get you the information. (I do not have a rooted/modified phone.)
Again, sorry for my mistaken report of success. In retrospect, I should have known it couldn't be that easy.
(Earlier this year, I WAS told by a developer in Colorado that there has been limited success with Sprint S4 minis being unlocked for GSM both internationally and domestic. And a Sprint rep recently told me that this phone can be unlocked internationally for GSM, although I see that it is not on their list of unlockable phones.)
mobile tower problem
mobile network is disabled in my phone samsung galaxy s4 mini sprint spark meid:99000437598028
how to fix this
I moved to Charlottesville, VA recently and the Tmobile coverage is really awful. Is it possible to take my rooted Tmobile Note 3 and use it on the Verizon network? I know it works on AT&T as I put my buddy's SIM card in and was able to connect to the network, but Verizon has the best coverage out here.
If I have to flash a new ROM or change the radio that's fine, I just need to know how to do it and if it's even possible.
No, not possible.

It is impssible to use a T-Mobile phone on a Verizon network. T-Mobile and AT&T run on the GSM type of network and Verizon and I believe Sprint run on CDMA which aren't capatible. It doesn't matter if you are rooted or not.

I've seen several instances of Verizon customers using their Note 3 on Tmobile. Just thought it might go the other way.
Verizon LTE devices come SIM unlocked for legal reasons (Verizon made a deal with the FCC not to SIM lock their devices in exchange for being able to use LTE Band 13 700 MHz).
Some of their older/"first-gen" LTE devices don't support GSM at all (e.g. Galaxy Nexus). But all nowadays do. The Galaxy S4 and newer support T-Mobile's LTE band. LTE is a GSM-based technology, and people travel as well. So pretty much all of their phones are GSM-enabled nowadays. Same for Sprint (except their phones will reject any US carrier SIMs specifically).
Anyways, the answer is no. AT&T and T-Mobile devices don't have CDMA enabled. And even if they did, Verizon and Sprint don't allow competitors' phones onto their networks.
