Unlocked, wont connect to data

Hello again. I decided to buy 2 sprint branded phones. One came sim unlocked. I used the NV method on the other. On both I can place calls, but data says disconnected. The APN's were downloaded straight from the provider (att mexico). And I compared the apn setting with a working M8 with the same sim.
I have tried full reset, and changing prefered network type in *#*#info#*#* menu. All it does is say disconnected. Am I missing something?

Update: got it working by flashing a custom rom. I used viper (selecting unlocked version on carrier select screen)

Debranded Sprint LG G6 - Lost APNs

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

Idea sim not working in Mi A1 after Pie January 2019 patch update

Hi there, I updated my Mi A1 through OTA to pie january update via Idea mobile data. But after it rebooted the network signal was gone. I tried inserting Airtel Sim card, it works.
It somehow has problems with Idea sim. The same idea sim works absolutely fine in other phones. Tried factory reset but to no avail.
Here is the list of things I already tried,
1) Inserting other operator's sim. Airtel SIM worked.
2) factory reset
3)Changing from 4G network to 3G or 2G. No use.
ANY HELP WILL BE APPRECIATED.

Same issue here, but on Cricket. I cannot make calls at all. I put this SIM in another phone and it works fine. I put the other working SIM in this phone and it doesn't work. Tried setting preference to 3G and 2G since I saw threads about VoLTE being broken by the update, but still nada. This really sucks. Can anybody help?

How to flash J7 SM-J737U To T-Mobile? Or one that does not have a sim card check on

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.

DO you have the global or the EAA version? If you have the global version you can try to flash full package of 1.1.4 to solve the issue.

How did you do the full flash? There is a tutorial in here where 1 command is false i think.
its flash fastboot xbl xbl.img but it should be fastboot flash xbl xbl.img.
Maybe thats what you need to repair but i think xbl image is about ram....

My imei is normal no problems

Maybe I can help with a solution: I have 2 SIMs and my mobile data suddenly stopped working one day. (It seems because the mobile carrier had technical issues in my area.) Now as I use mobile data only on SIM1 which I de-activated during the day in hope to get a connection back, I assume my preferred SIM changed (see Settings -> Network & Internet -> SIM Cards: Standard SIMs) to SIM2 for calls and mobile data. As the phone tried SIM2 for data but it is de-activeted there, both networks had a small "!" near the radio indicator. After settings the preferred SIM back to SIM1, everything is working fine again.

The problem is that the cell phone doesn't recognize any chip, so I can't open the sim card options

Hello i have also updated to 1.1.4 and after around a month it is also not recognizing my sim card. The sim card works on any other phone. I have tried rebooting, soft restarting, resetting all network options, I even changed the sim at the store. Nothing has fixed my issue. My last resort is factory reset.
Has anyone found a solution?
