Has anyone successfully unlocked the phone yet? Looking to buy a Canadian version and need to unlock. Usually use cellunlocker.net, but didn't need it for the S3 or Note 2 that I've had
Wasn't sure where to post this as there wasn't an option for Cricket S4. I am however trying to switch this to Bell so i thought this may be best.
Hello folks, I recently purchased a Samsung S4 from Cricket Wireless. I need to unlock this unit to work on Bell Canada which runs CDMA and GSM technologies. After alot of discussion with Cricket they did end up giving me a 8 digit unlock code. The problem is it runs on CDMA and when I take the Cricket sim out to install the Bell sim it doesn't give me the option to enter an unlock code. I did the dialer option and that didn't work either. All the phone says is invalid sim.Thank you all in advance.
Any luck unlocking S4
HI, I know its been a while since you posted this thread but I just came across it. I am trying to get a Cricket S4 onto the bell network and need to unlock it. Did you ever have any luck unlocking yours? I would greatly appreciate it if you have any advice for me. Thank you very much.
How to unlock the Samsung Galaxy S4 SCH-R970
I bough this phone online thinking that i will unlock and keep using on different carriers even outside the US (GSM)
I have done a lot of researches online and i cannot find any solution. The imei is only 14 Digits and almost all online unlocking services doesn't have this model.
The usually codes like *#0011#, *#27663368378# they doesn't work at all.
I have tried to go to unlock stores or guys who knows to unlock phones and he said that this phone cannot be unlocked.
phone has a sim card slot so it should be CDMA&GSM
When i insert a different sim card provider it says Invalid Sim Card so i cannot enter any unlock code
ANY IDEA or i will lose 500$ for bad phone
Uscc is not a gsm phone the sim card slot is used for thw 4g service the phone itself is cdma

Samsung gs4 sch-970c (cricket)
Samsung has told me this phone will work either gsm or cdma. Cdma is the way cricket first sold it. It cannot be unlocked. It is cdma. It has to be flashed to a new carrier after it is rooted. The sim is locked via software. Not many codes and all the unlock codes you read about are for gsm. The ##366633# code you mention gets you to a disable or enable developer mode.
i also have the same issue. Not resolved yet. but I did find out this that might help: if i pull up a website that checks the MEID number it gives me the whole description of my phone plus an extra digit on the IMEI number. I wonder if this is why third party unlock sites cant help me
Who has unlocked cricket sch-r970c?
Same problem. Cricket said they cannot find the unlock code if the phone was never activated. So this was never activated.
I have rooted it to OptimizedCM-12-1-20151130. Is it now unlocked?
OR, who has successfully flashed a custom ROM to unlock the software lock on it?
The struggle continues...
I just repaired my USC s4 LCD digitizer and now that I am no longer a USC customer wanted to unlock it so I did some checking, if you go to US cellular they will unlock the phone for you, I got my unlock code, but they said they couldn't complete the process if the phone was rooted (Which mine is), you would have to reinstall the USC original firmware, or the latest firmware, to get it to unlock, then root it. I am doing some research now to find out if there is indeed an alternative to unlock a rooted phone...
I just left US CELLULAR where I was told nothing below the s5 could be unlocked,and the only suggestion from any one employed there was to call customer service.
you try RegionLockapp ???
I unlocked my t mobile s4 with it, i had to flash to a earlier firmware, then root, then use RegionLockapp, then re-flash whatever rom you want.
I have done lots of reading on this and I am still not sure if the solution really exist ...
AT&T Sansung Galaxy S4 i337 MF3 build
1. Having MF3 build, none of the easy unlock solution worked.
2. Can I go back to any previous stock ROM from MF3 such that any of the easy unlock process would work?
3. Will the rooting methods using this be able to sim unlock my device?
4. I assume not, but will updating my MF3 build to any recent ones (MJ6 or MJ9) solve my problem?
Ultimately I want to unlock my device without having to pay $20- $30.
Any help will be appreciated.
Thanks

Lucky you, I just SIM unlocked my friends Galaxy S4 i337 MF3 from AT&T last night so I can tell you your options.
If your phone is off contract (fully paid) you can call AT&T and ask them for an unlock code.
Pay $10-$30 for a factory unlock code for your device from Ebay or whatever.
Root your device, block the AT&T updater from updating you to 4.3, and get the app Region Lock Away from the Play Store.
AT&T denied us the unlock code so we went with the Region Lock Away app from the Play Store and today my friend just activated his AT&T S4 with a T-Mobile prepaid plan. They transferred his number within a couple hours (4 hours or so) and he's been playing with 4G LTE, texting and calling all morning. He hasn't had cell phone internet before because AT&T is so expensive so he is pretty happy.

I did it and it works. My phone is unlocked now. Is it safe to update to 4.3 now ?

Probably not a good idea. The unlock is a software unlock so updating it might remove it and you might lose root capability as well. For now, wait and see if you can still root after the update. If you can, then you can update, root and reinstall the Region Lock Away.

Had this experience before. Purchased an S4. Then tried to unlock through the service menu based on a XDA tutorial. Didn't work and it could not be unlocked with a right unlock code later on. Eventually, I returned it and get another S4.
This happened to me on galaxy s4 but it was my mistake. My s4 was rooted and I had attempted to unlock using region lock away for unlocking region lock. But when I received the unlock code(sim unlock) i forgot i had left my region lock away on. So i had to reverse that region lock away (or just restored my phone) and retried the code, which then worked fine.

Did you ever find a solution?
Check out the second post here https://forum.xda-developers.com/galaxy-s7/help/help-awesome-t3605470
The certain carriers are Cricket / ATT. If your NCK is not working, you have to get the MCK code. I have a special hotline you can call about the issue since normal att tech support cant help. check your pms
