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.
Hello everyone i could use some info regarding The Sprint Galaxy S3 [SPH-L710]
So im getting a new phone. i work at walmart and noticed that verizon released the galaxy s3 for prepaid.. I decided i wunt it but theres a problem i have to be able to use it as a Hotspot in order to do that i needa use pda net witch requires Root. I have looked and looked and looked and found out that the Prepaid Galaxy s3 [i535PP] can NOT be rooted, but the non Prepaid version of the galaxy s3 [i535] and the sprint version [L710] of the s3 CAN be rooted... so if i had a non prepaid version of the galaxy s3 i can root it and use it as a hotspot with pda net. i did some research and found that the sprint Galaxy S3 L710 can be flashed to verizon =) so i searched ebay for a sprint galaxy s3 flashed to verizon prepaid and i found 1 listing with a guy that has a Sprint L710 Galaxy S3 and i wunt to buy it and root it.... So here is my question
I researched Sprint Galaxy S3 and read alot about 4g not working... im not 100% sure if this is a issue with the phone itself or sprint the provider but If i buy this phone and its flashed to verizon prepaid will the phone be able to get 4g signal/service
Verizon recently released 4g on prepaid network and id like to use it with this phone.
bottom line is will a Sprint Galaxy S3 Flashed to Verizon Prepaid Be able to access 4g signal??
Thanks in Advance!!!
Nope no 4g service if the phone is flashed to Verizon prepaid. At least Verizon's LTE.
Now you can get 4g but from a sprint provider. Either ting or freedompop I believe. I use freedompop. You only get 500 mb of data but you can pay more if you need more.
Sent from my SPH-L710 using Tapatalk
No. Verizon's 4g operates on a completely different frequency then Sprint. You will be able to use 3G and 1xRTT and that's it.
aww man that sucks oh well... ok well then i have a different question. What if i were to buy a non prepaid i535 verizon verson, can it be flashed to verizon prepaid and if it can be then can it be rooted??? if so then ill have to research how to flash a i535 the reason i need verizon is because its the only service that works in my area and it bairley works at that..
I am on TMO but I got a great deal on a Sprint S4. Given the proposed merger between Sprint and TMO I was wondering if the Sprint version will work on a TMO data plan. If not, will Sprint unlock a non blacklisted IMEI to allow its use on TMO?
Thanks
I believe Sprint is CDMA and TMobile is GSM so I don't believe you can use it on TMobile today. You'll have to call TMobile to confirm. If they do merge most likely they'll quickly have SIMs to support the tablet. So I'd hold onto the tablet.

Doing some additional research, LTE is based upon GSM, not CDMA. The Sprint version has a sim card slot. If I can get it unlocked it should work fine on any other LTE carrier using the same frequencies. There's a store in town that charges a fee to unlock devices. I'll stop by and see if they can unlock my S4. It is also interesting that the Sprint version does not have the word "Sprint" printed on the back. I wonder if the Sprint version is the same as the international version locked to Sprint.
