[Q] Unlocked, MMS#3 on AT&T help

I have a galaxy S5 on AT&T that I'm trying to use a straight talk sim in. (Att towers) whenever a sim is inserted into the phone I get "Sim not allowed mm#3". I used a reputable service (cell unlocker) to unlock the device. The IMEI comes up clean as well. I've also changed the APN settings, but it won't connect. I'm trying to port from a galaxy s3.

I would also like to quickly add that the t mobile straight talk sim works just fine, but using that is not an option as the service is atrocious.
Another thing, the ATT sim works in a galaxy S4 with no issues. They are both sims for straight talk. Any help is really appreciated, this is baffling me.

Just went into the service menu with *#0011# and in the debug menu i can't actually see a MM reject cause. CARD_ERROR: Unknown and PERSO_FEATURE: UNSUPPORTED are the only relevent info i see here. The phone has been unlocked, is there a way to flash the service menu with ODIN and reset it all to stock? I know this won't lose the unlock, so in the off chance that I did accidentally click on something in there before will the tar.md5 file fix this? I read a post where user sanquante said he had to flash the PDA.MD5 file and it fixed it...I'm assuming he meant the tar.md5? Thanks for ANYONE willing to help. I really could use it.

got Sprint to unlock now how to change carrier options.

OK, I finally got Sprint to uicc unlock my phone yesterday. Now I need to figure out how to change carrier options., any help would be greatly appreciated. Also now that it's carrier unlocked shouldn't I be able to access the hidden menus and stuff or can I only do that after root?

No getting unlock didnt change anything. It just unlocked the uicc slot for a different sim. Have to get another sim and pop in phone and then you can set ur apns for that network.
Nothing else gets "unlocked" and is nothing near the access root gives you.

That's what I thought ugh. But I've tried to do that and can't get the APN to save.... I've tried to edit it with##debug# I have my msl also. And I also like I idiot purchased a unlocking app off eBay and all it was is hidden menu apk. You can add APN with that but still don't save. I inserted my Verizon sim card in the phone and it shows me roaming for service. I'm going to root my phone hopefully tomorrow afternoon. Once I do that the way I understand it that I'll be able to change and access more things. Sorry I'm a newbie when it comes to rooting, can do a lot with phones but some stuff is all new learning experience

Dont need to root.
If you have msl you can use cdma workshop or another efs program. Need to change ur prl to a vzw one. Then set apns.
Root will fix the issue with apn not saving as the hidden menue stuff needs root to activate the right menues.
But you should be able to swap prl to vzw one and put in sim and do *228 to activate. But rooting will make easier.
Root and flash a vzw rom and profit instantly lol

Quick question? i have the vs997 and i rooted and flashed the vs996 to utilize my Verizon sim. I am able to access and edit apn settings, lte and such work fine but are you saying i could flash a verizon rom to this vs997 so i dont have to use the vs996 rom with the debug kernal?

OK I'm want root also cause I want to tinker lol, I love messing with the different menus and stuff. I'm kinda nervous to root cause will be first one and don't want to make expensive paper weight.... But I ran into some issues the other day with trying to root but didn't know needed SD card and couple other things. But like other guy said I can flash the VZW ROM and be golden? Also will I pick up all the band's that VZW towers put out?

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

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
I gotta find someone

XT1767 (VZ Moto E4) FreedomPop SIM Card Problem

I've been using my unlocked XT1767 with my Global FreedomPop GSM SIM for months without issue. I also tried my TMobile SIM which worked fine as well. I went to try my Virgin Mobile SIM (Sprint) last week and after the phone powered on it said something to the effect of "Unrecognized SIM, locking SIM." I promptly turned it off and put my FreedomPop SIM back in and now the phone doesn't recognize it. I get an X on the signal indicator and the usual "This is not a Verizon SIM card message." I tried a TMobile, MetroPCS and ATT SIM, all which are recognized. The TMobile SIM is the only one I have service on and I verified data is working. However, both of my Global GSM FP SIMs give the X in the signal bar.
What happened?

Maybe try a factory reset?
Did you try resetting the apns and network settings?

I tried the network settings reset and a factory reset without success. I'm baffled.
It's worth noting the aforementioned FP SIMs work fine in other devices.

What ever happened, the sim card didn't agree with the modem. Try booting to the bootloader and with fastboot run the commands:
Code:
erase modemst1
Code:
erase modemst2
Then reboot and see what happens. I don't think I would try the sim card that caused problems again.

Thanks for the ideas. What ended up fixing it (after another factory reset) was to go to settings > wireless and networks > cellular networks. This caused the app to crash. I re-opened settings, went back in and was able to hit "search for networks." Then FreedomPop showed up and I could select it. After entering its APN I'm in.
It's all very strange. I don't know how any of that could have persisted after resets.

S8 unlocked but no service

I bought used S8 that had clean IMEI (not blacklisted), it was locked on Sprint and with financial eliglibity. Before I got it unlocked it didn't recognised any sim card, after unlocking it did regular setup on my ATT card with all the ATT apps but it doesn't have service. Then I tried with Verizon SIM and it did the same, regular setup but no service. What do you think what's the problem ?
Phone build number : R16NW.G950USQS3CRE2

Is it rooted, and if it is, have you uninstalled any system packages
If not, try a factory reset and making sure the sim is active and APN settings are working and you have chose a network

It's not rooted, I did remote unlock with unlocking service and they flashed original firmware on it, nothing should be messed up.
I did factory reset few times as well as network reset. I double checked APN info and ofc it's setted up together with card.
I forgot to mention that phone is not showing up IMEI, actually nothing when I type *#06# in dial

that mean you lost imei ....flash factory firmware by yourself...it will do the trick

Can you explain me which one I need ? What about bootloader, is it the same ? I've checked thread about bootloader and mine is "carrier firmware", not unlocked.

Which career search for career. Look at the build number in abiut and search for that.

I'm using ATT and my phone was locked on Sprint, so I flashed Sprint firmware and It's the same. I put the SIM card in, it did ATT setup and all of the apps from carrier but it's still block sign instead of signal sign in top right corner and airplane mode is light blue (not usual blue like when you turn it on)
At least this time it's showing up imei in dialer
I couldn't find ATT firmware, if someone knows there's my build number in first post.
