A member of my family has a GS9 under AT&T, and they decided to buy a Straight Talk SIM under Verizon's networks, but AT&T is GSM and VZW is a CDMA network!
I am worried that it won't work, so can someone tell me if it would even REMOTELY work.
I don't want to switch any CSC files, as they don't want to lose data, and I can't really find a stray G960U VZW HOME_CSC.

Hello guys,
I have been reading all I can about the TP2 on different networks and I'm taking the plunge to buy an unlocked TP2. The only problem is that I'm torn between which one I should buy. I have searched all day and havent found the answer.
1) I like the features on the Verizon version but I have a deciding question - Can the Verizon version be used on the TMobile network? That is very important for deciding.
2) What problems am I likely to face using unlocking/HARD SPLing the Verizon version to work with the TMobile network?
I use TMObile at the moment with no intentions of switching carriers.
I would appreciate any positive help. Thanks
No-
VZ is CDMA and TMobile is GSM -
Not compatable
Prubin is right, but not telling the whole story.
A fully unlocked VZW TP2 will let you use a TMO SIM card and you will get GSM calling. Just no 3G on data, only EDGE speeds as the VZW TP2 does not have the proper UMTS bands.
I'm using with both Verizon and prepaid Tmobile (only 1 at a time). You will need to sim unlock as well.
As previous post stated, you lose 3G, only EDGE. Prepaid has no data but I was able to browse t-zones sites just fine. And you'll probably lose Tmobile specific apps.
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.
I want to get this phone but might want to switch carriers soon. I was planning on doing the Sprint EasyPay for it and paying off the rest of the phone if or when I decide to switch carriers. After I pay it off in full and unlock it, would I be able to use it on T-mobile, AT&T, Verizon, or any of their MVNO's? Basically what I am asking is does the Sprint S6 support the necessary bands that the other networks operate on, and if so, would calling or texting still work? I have heard of some phones that have a SIM card slot for the LTE SIM on Sprint, but voice and text don't work once unlocked and used on another carrier.
Thanks,
Kyle
I would really like to know the answer to this as well. I have been searching without a definitive result.
Specifically, can unlocked Sprint phone be used on Verizon?
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.

First of all let me say that before u answer this question I have about as much knowledge on this as a 75yo grandmother, so please keep it extra simple. Most of what I read on these forums might as well be Greek. I have an LG G7 ThinQ. More specifically the G710VMX. I purchased it unlocked and brought it to Tracfone, yes I use Tracfone. It worked with the original SIM card I had from another phone until it didn't, that's when the issues began. Bought a 3 pack VZW, T-Mobile, AT&T sim kit intending to use VZW because has the best service in rural areas. That sim would not work so ended up with T-Mobile sim and bad service. Assumed the phone was GSM only so I suffered. Then I tried to put in an AT&T sim to see if that would give better service and it's GSM so I thought it would work, well it doesn't. Somehow this is only compatible with T-Mobile and US Cellular which is CDMA(? since I assumed phone GSM only). Now Tracfone and T-Mobile reps both are telling me that once they switch to VoLTE the phone will no longer work, I will need a new phone. How is that possible?? I love this phone and hace read that it is capable of operating in VoLTE but the setting to turn it on is not there. And all other networks when given my IMEI tell me it's not compatible. HELP ME PLEASE, I can't afford, nor do I want, a new phone right now.

time will tell, you know just use your phone as long as it's still working. don't let marketing fool you
Well, the other issue is that I need to get it away from Tracfone T-Mobile because their service is terrible in my area. I can't seem to get either a Tracfone AT&T or Tracfone Verizon SIM to work yet the phone is compatible (according to the websites respectively) with Cricket wireless (AT&T) and US Cellular (cdma). I don't understand... That is why I brought this question to all of you. I live and work in a rural area and it may sound crazy but all I want to do is make stinking phone calls.
