Hi, first off I know that this is the Verizon section but there isn't a spot for U.S Cellular. OK, I have received a Samsung Galaxy S3 Model Number

SCH-R530 because the screen is barely cracked. The person got a new one and now I have this one. I have I Wireless for cell service which is a T-Mobile

affiliate. I Wireless uses GSM and I have a Mini SIM card in my Galaxy Nexus. When I dial the *#06# on the Galaxy S3 a MEID number comes up. When I

take the battery off and look there there is one IMEI and 2 MEID serial numbers. If I am correct I think IMEI is for GSM. This Galaxy S3 also has a SIMcard in

it which I thought CDMA doesn't use. It is a micro SIM and says US Cellular 4G LTE on it. Is there any way I could unlock this Galaxy S3 to use on my GSM

network? Please help. Thanks

It will work for gsm networks but you have to be rooted, edit the apn and i beleive you can only run 2g data. There is a thread about it somewhere around here on a howto for tmobile. And to the other person who said the sim is only for lte is correct, for verizon that is :p

Could you point to that thread please? Because I have a NOTE II US CELLULAR that I would like to unlock to use on AT&T. I don't mind if I get 2G data. Thanks

If you root it then upgrade to AOKP 4.1.2 custom ROM or any other custom or stock style ROM thats 4.1.X (Jelly Bean), then there is a REALLY easy trick. I know it's harder for US Cellular only because they are still using 4.04 ICS which doesn't support the menu you need to do this, you need JB for this trick, if you have it stock like on T-mobile then no rooting or upgrading needed, but US Cellular it is. I used it to unlock my tmobile, and my friend and mom both have us cellular. After you Unlock it you can always go back to stock if you want, just make sure and after you root but before you upgrade the ROM you do a nandroid backup to go back to. After you have a Jelly Bean ROM installed,
1. Type *#197328640# and it brings up the factory service menu (very usefull)
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off, Passed that is a screen that says something like "no options in this menu, current command is 11863", Wait for 30-60 secs, from there hit the menu button on bottom left of phone to bring up options, Select "Back".
7. The last command should have brought you back into the Network Lock menu, at the bottom is (4) NW Lock NV Data Initialize, Select it. You might be asked a saftey are you sure, some people not, after it begins that process wait a good 60 sec the reboot. Thats it! Phones Unlocked :)

It would be good for you to root and upgade a custom JB 4.1.x or higher ROM anyways as they have support and menu options for working on all CDMA/GSM/LTE Networks. Even if you unlock your phone using the IMEI number and paying 20$ for the unlock code, you will still need JB. They also have apps on the play store specifically for galaxy s3's, capable of unlocking for allot cheaper if your phones rooted.
Good Luck!

So, let me know if I'm correct

I have doing some research online, and I just want to know if I'm correct, Please, please someone answer me:
1. All Samsung Galaxy SIII, by US Cellular, even though using CDMA, ALL contains a SIM Slot for GSM network? (being one of the few)
2. Since it contains a SIM Slot, in order to work in a GSM network, one alternative could be to get it Rooted, and then use an Unlock Software?
Please somebody answers me, I bough a SGSIII on Ebay, and just found out about this.
Thanks!

Ok. I've rooted and flashed aokp 4.2.2. :D but can't get the number to work. :crying: doesnt do anything. what am i doin wrong?
 
Hey Everyone..... I'm here to say that this DOES WORK just fine and dandy. But there is a step that no one is telling anyone or else no one knew. You have to first unlock the hidden menu before it is accessible. Go to your dialer and type the following in and then change to "Enable". Press *#22745927 to enable hidden menu. Once done with that go back and follow what the previous guy said to do........

    I rooted my sch-r530u and cant find any menus mentioned above. when I dial code it says no network. I have the update toolkit for my us cellular phone but really lost with the apn and diagnostic menu. also ive heard that if I flash to straight talk I wont have 3g is fixable? I have been reading every forum I could find and I am almost completely out of options or feel that way

    What ROM are you on? Aosp/aokp do not support USD or ussd codes ( what ever that is called) you need to be on a stock/custom stock. Some devs may remove it from custom stock as well. So pay close attention to you ROM type and version.

    I will be stepping in soon to try this on a d2usc/r530. I am a T-Mobile user. I had the d2tmo. Currently nexus 4. I need to repair the R530 and once I do I will help out. One thing is download mskips tool kit. Good luck.
