I just got a Sprint galaxy note 3 and im trying to make it cricket with the new gsm network. I ordered a sim card and I attempted to do the sim unlock but it is not working. I rooted it and verified that it is rooted with an app to check it. I also installed super su like the directions said and also installed region lock away. I still cant get the phone to accept the sim. It says "invalid card". I checked the Stats on it and it show network unknow. It doesn't even show the phone number program onto the sim. When I take it out it switches back to sprint.
Sprint sim slot is only for lte on sprint in the us...
You need a gsm model such as att or unlocked t-mobile note 3!
S7 Edge permanently locked to AT&T network (Too many network unlock code attempts)
Hello all!
I've moved to Korea with my fully purchased AT&T S7 Edge (SM-G935A) from the U.S. I went to a local authorized phone service shop in Korea and purchased and linked an SK Telecom Nano USIM 3GB data sim card to my phone and then entered in too many unsuccessful network unlock code attemps. I wasn't aware that if too many failed attempts are entered, that the phone would lock permanently to AT&T network :/.
I then contacted AT&T and got the official authorized network unlock code, but that isn't working. Neither did the unfreeze code I purchased from an unlocking site. I then found the XDA forum and successfully flashed my phone to G-935U (http://forum.xda-developers.com/att-s7-edge/how-to/updated-935u-935a-live-links-pi3-t3501686). After inserting the prepaid Sim card, I'm still receiving the network unlock code screen where the AT&T network unlock code, unfreeze code, and codes on Sim card packaging are not working.
Can anyone advise any solutions? Is there a way to reset or get around the hardlock / permanently AT&T network lock?
Thank you,

I have had hard locked phones before, here's how you can get it fixed. If its still under warranty, and if you can get it to samsung usa, tell them your phone is stuck due to a bad update. They will reflash your phone, and when they do this, with their methods, it restores the modem firmware and the original sim's lock(no more hard lock). & they will reprogram your imei and serial. So your unlock codes will work now.

I have an edge that is unlocked by tmobile.. in the app, permanent unlock (tmobile unlock app), it says.. "unlock failed" but below says permanently unlocked, unlock approved.. my understanding is this is a normal message.
When i went to the ATT store to test a sim.. they use their live sim, put it in, try to make a phone call but simply said it didnt work, isnt unlocked, which i dont think is right.. issue is i didnt see what if any error message there was.
Is there some step that the att rep should have done to get this on the att network besides putting it in the phone?
Thanks in advance for any info
edit: appears a special sim is needed, at least according to an online rep.. i was told to have them look up the IMEI with the MyCSP tool in the store to determine which sim.
Hello readers and devs,
TL;DR
Debranded a Sprint LG G6 --> Factory & Hard Reset phone --> SIM card not being read.
-----
Need help getting my phone back on MetroPCS network after a debrand. I will try to be a thorough as I can for SEO robots and to explain as best I can what I did and what I noticed changing.
!!! action --> I debranded (unbranded, sic) my Sprint LG G6 993 phone using the code provided in the forums, hoping for the best.
I noticed the following changed after debranding:
APNs were locked (not able to create new or edit, however the MetroPCS APN was still there)
Sprint logo during boot gone
WiFi Calling option gone (was not working on MetroPCS network anyway)
mobile settings -> network mode -> GSM and Automatic options missing; set to LTE/CDMA
the cellular network connection to MetroPCS was not functioning properly
SIM card error when a phone call was made, no texting either
So, I naturally read through the forums to try to get the phone working properly again on my network. I read the topic Sprint LG G6 (LS993) Dial Codes.
!!! action --> I used the code ##72786# to "Reset provisioning and makes phone reactivate".
After that, I noticed that the MetroPCS APN was removed. APNs still not editable. At this point after reading some more on the forum I decided that I needed to get the phones MSL code, go into the service menu and edit the APNs from there. However, after getting the MSL and going into the service menu area, the APN area would still not allow me to edit the fields.
I went to MetroPCS to see if they could put a new sim card in the phone, hell for all I knew maybe my sim card was bad, remember when I try to make a call I get a SIM card error message. MetroPCS guy tries some things, calls up a service person on the phone, says nothing is wrong with the sim. Tells me to come back in 30 min. I go over to Sprint, give them the phone and tell them what is happening. They say the phone IS unlocked. Then a sales rep tells me that debranding the phone means that it is no longer a Sprint phone and they will not touch the phone. I ask nicely for a tech supervisor. Sprint supervisor says that I should try to Factory Reset the phone. I go home, backup the phone and do a factory reset.
!!! action --> Factory Reset the phone.
Changes:
mobile settings -> network mode -> GSM and Automatic options appear again; set to Automatic
Still unable to add or edit APNs (the APN area options are all greyed out).
!!! action --> I take out the SIM card and put it into my previous phone (Samsung Galaxy On5) thinking well i need a working phone.
I get an error, On5 is not connecting to the network, needs to be activated.
!!! action --> I take out the sim card and put it back into the LG G6.
Changes:
Invalid SIM card error (phone does not detect the sim card)
The SIM card is not being detected by the phone.
I read the forums some more and discovered a post that referenced a LG G6 that was debranded and to get it working again the owner had to buy a Sprint Prepaid activation SIM to re-provision the phone to get it working again on his alternative network.
I downloaded a SIM Card reader and the LG G6 doesnt give me any information on the sim card. If I put the SIM card into my On5 phone and use the SIM Card reader app I can see that my SIM card is okay and all data is displayed properly for the SIM.
I am not really sure what to do, but try to get a Sprint SIM card and put it in to try to reprovision the phone to Sprint and then move it back over to MetroPCS.
Please help what should I do now to get the phone back on MetroPCS?
Thanks,
Trumpet

Debranding?
The boot loader is locked so how can you modify anything on the phone?
First I would kdz back to stock.
That is install the version of software unaltered that should have come with the phone.
I'll leave it up to you to search in the QA section.
Once that is done, confirm the phone is unlocked.
You should need to do nothing more than to drop in the Metro SIM to have it work.
If the phone is not unlocked you will get "invalid SIM" messages.

Firstly, thank you for the read and reply. I was able to debrand the phone utilizing a dial code found in this thread:
sprint-lg-g6-ls993-dial-codes
The thread states:
"##27263# (##BRAND#) - Removes any carrier branding and redetects the carrier based on (NV registry/RUIM/SIM?).
Note: Useful if flashing to Boost Mobile or similar carrier."
After debranding the APN area became un-editable.

I checked this thread:
list-lg-g6-stock-firmware
At this time there is not a Sprint LG G6 KDZ.

I need to confirm that the phone is unlocked. I did have a conversation with Sprint technician that said it came up unlocked in their system. It could be possible (although I don not know for sure) that the phone's hardware/software is locked and yet Sprint cell network has the phone unlocked in their system. Maybe I need to purchase an unlock service for the phone?
Have you tried this thread? https://forum.xda-developers.com/sprint-g6/help/mobile-gsm-data-issues-unlock-t3625705
I have the same issued. After "debranding" I can't add a new APN. In my case I do have voice and SMS, but no DATA since I can't add an APN.. Were you able to fix your phone. Please share the solution if you did. Thanks

Im also having the sam issue
The only way to fix this is to insert an active sprint sim card with service and dial ##72786# to re-activate
Since i switched to metro pcs ......my sim service is not active

is your problem solved?
same problem
i have the same problem but i select de uicc unlock and works my mexico sim but just only voice calls and text. apn still greyed out and says otasn on apn settings grayed out too. any solution for this ?
Try this:
Dial 5689#*993# ; go to NAOT + NAO Test + NAO CARRIER (Select NONE).
After that you will be able to edit/add APNs
Sorry if this is posted somewhere, but I could not locate it. I bought a consumer cellular SM-J737U, which runs on att and tmobile towers. When I inserted the t-mobile sim, it prompted me to reboot for network change. I did, and I have full LTE for a few seconds then I got an error message saying this is an invalid sim, contact consumer cellular for help. So I know the sim works because I had full connectivity on there.
What do I need to flash to goto stock J7 stuff so I can use my tmobile sim?
I tried another sim and the same thing happened.
