I would like to use my T-Mobile Galaxy S3 on Straight Talk on the AT&T network. I'm currently using Solavei running under T-Mobile's network, but T-Mobile isn't cutting it in my area. I really want to run on the AT&T network. Solavei only runs on TMO.
TMO is great when I can get 4G but it sucks when others in the same physical location can get AT&T to 4G and TMO is E or G network.
Examples of where AT&T is working great but TMO isn't are: up in the canyons (Millcreek, SLC, Utah), over the dunes at the beach (Topsail, NC), at my house (SLC, UT).
Questions:
1. Can I do this? Run a T-Mobile Galaxy S3 on Straight Talk on the AT&T network?
2. If so, If I buy a sim from Straight Talk what does it take to make sure it runs on the AT&T network and not on TMO? I'd really hate to go through all that and still end up on TMO and not AT&T. I've already had an AT&T sim running in my Galaxy S3 and everything was working great. I just didn't want to pay AT&T prices.
3. I've heard that Straight Talk will switch from TMO to AT&T depending on what area on the country you live in. Is this true? Is there anyway to override this?
4. I've heard that you can't buy AT&T sims anymore from Straight Talk. There seems to be a market now for AT&T sims that were available at the beginning of the year but are not now.
PS: I'm trying to do this for the TMO Note 2 also.
Yeah you can use tmobile's straight talk on at&t network. Just pop in sim and select roaming and available network select at&t. Should connect no problem

You have to SIM unlock your phone first as it won't take an at&t SIM out of the gate - either call T-Mobile for the code or you can follow this method - http://forum.xda-developers.com/showthread.php?t=2023709
Note that if you are the latest radio (MD5), you will have to downgrade it to LJC or LJA for the radio unlock option to appear - the radio images can be found here - http://forum.xda-developers.com/showthread.php?t=1880987
That trick works on the Note 2 as well, however, I don't know if the radio is an issue with the Note 2 you will have to check the Note 2 forum but chances are if Samsung updated it, you will have to downgrade the radio to get the option back.
StraightTalk will not sell you a SIM for at&t if you don't have at&t service in the area - at&t's StraightTalk SIM does not roam on T-Mobile except rarely as at&t's roaming agreement with T-Mobile is extremely limited.
One final thing, I wish you good luck. StraightTalk was a horrible experience for me and at&t throttles you like nobody's business. On the plus side though, Tracfone's wholesale contract with at&t means that you get access to their POSTPAID network which means you get better coverage than at&t's own prepaid or any other MVNO of at&t for that matter.

This is not what the OP was asking. He wants to switch his T-Mobile branded S3 with T-Mobile branded service to StraightTalk using an at&t SIM and service.

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.
IT WORKS

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

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.
As you know, all verizon lte phones are unlocked. So I inserted a att sim card to verizon g3, im not getting ANY signal. If you want to argue that verizon lg g3 is cdma only, go google it, its compatible for both gsm and cdma. anyways back to story, I tried changing apn, settings to lte/gsm/udtp, still nothing. I tried 3 different sims, verizon sims works fine but its at&t sims im having trouble with.
I'm looking to bring an unlocked AT&T Note 5 over to use on VZ.
Is it possible to flash VZ firmware and have the phone work just as if it was a VZ to begin with (and receive 3g data, text, and calls) or is that something that's hardware related and flashing the new firmware won't help?
I've found this information, so I know the consequences of using an AT&T phone on VZ normally...
"If you're hoping to use your unlocked AT&T phone on T-Mobile, you should have no problems. Both carriers run their networks on GSM technology, so once your phone is unlocked, just pop in your new T-Mobile SIM card and you'll be up and running. AT&T and T-Mobile both use Band 4 for their LTE service, so 4G LTE devices should be able to access the network without issue.
Although Verizon uses the CDMA standard and not GSM, you still may be able to use your AT&T 4G LTE device on Verizon's LTE network, as they both run on the same spectrum; so LTE data should, theoretically, work fine. However, it's unlikely that you will be able to make or receive calls and texts, or access data over Verizon's 3G service.
Sprint is also a CDMA carrier, but runs its LTE network on a different band of spectrum than T-Mobile, AT&T and Verizon; it may accept selected AT&T devices on its plans, but you'll need to check first."
I'm curious, because I rooted an flashed the unlocked software on a friends VZ's s7 for use on Republic wireless, so I know this sort of thing can be done. I'm just not knowledgeable about the differences in these 2 scenarios.
Thanks so much in advance!
You can't flash any firmware on the AT&T note 5 other than official AT&T note 5 firmware because the bootloader is locked. I'm not sure about the part of using this Note 5 on Verizon.
