So I obtained a GN2 SPH-L900 from the Carrier CREDO NETWORK that uses the Sprint network towers.
It can not be activated directly on the Sprint Network the way its flashed now. It has a virtual SIM card.
How do I go about unlocking it so it can be activated directly on the Sprint Network? Any help or direction would be appreciated.
CREDO will not release the lock codes. Sprint can't help me. Samsung won't reflash since its out of warrantly.
Thanks.

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 have a Samsung Galaxy s3. I plan on making Cricket wireless as my carrier. They are affiliated with AT&T. My question is how will i be able to root and flash roms with Cricket as my carrier? Do I use the AT&T thread for the s3? Anyone's help would be appreciated.
Cricket is indeed a At&t subsidiary so by all means a att s3 will work on cricket. And just continue to use your phone as you normally would......just keep those cricket apns with ya and the cricket Sim and you should be golden.....and yes if you have a att s3 then continue using att Roms like you normally would
S6 Sprint CDMA to GSM
My brother handed me a Sprint S6 that he paid off and said was unlocked by Sprint OTA. He wants to use it with Consumer Cellular or Straightalk GSM service. He also has the unlock code provided by Sprint. Since this is currently on a CDMA network, can it be modified by flashing another rom, to GSM. I know the phone is capable of using both network types but realistically can it be done. If so how ??
Thanks in advance for your expertise
A quick forum search will answer your question
Hello,
I recently joined Sprint's network. I am aware that their phones are CDMA-based, unlike T-Mobile's and ATT's, which are GSM-based.
My mother has a Note 3 in good condition that she is getting rid of, and I'd like to keep it; but it's a T-Mobile model, and have been trying to find info. about whether or not the phone can be made to work in Sprint's network after unlocking it.
Any information is greatly appreciated.
No, 2 different types of radios. work with any GSM based carrier like T Mobile AT&T etc but not sprint
should work in 2020 as sprint is now owned by tmobile
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.
