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.

Hoping for some knowledgeable assistance here because FreedomPop has been no help. Two issues, probably related:
I have the SPH-720T 0A3 activated with FreedomPop but it only works over WiFi. I can't connect over 3G/LTE.
I get the Sprint Hands Free Activation on bootup and whenever I try to update Profile and PRL.
I'm rooted and have TWRP. I've tried a couple of ROMs, but they had the same behavior, so I reverted back to stock. I tried changing to CDMA mode and that brings up the 3G icon, but still no data access. It boots up with no APN checked and without the FreedomPop APN; I added the FP APN, but it doesn't help and disappears on reboot. I tried changing MDN and MSID to my FP phone number, but that also hasn't helped and they revert back on reboot. Mobile data is on.
I would appreciate any help on figuring out what exactly the problem is and whether I can fix it or if there is something I can go to FreedomPop or Sprint with and tell them what needs to be done. I'm new to all this but don't mind learning or following directions.
Many thanks.
I spent a couple of days trying to find a solution for this, but I cannot. So I hope somebody can help.
My phone is rooted an unlocked. It was once a Sprint phone. I have my own MSL code.
Many forums advice that you enter ##DATA# and tweak
APN2LTE internet and APN2 EHRPD and write default,mms,dun.
The problem is that my DATA screen doesn't show APN2LTE internet and APN2 EHRPD
All I see is APN.
When I change the APN TYPE to default,mms,dun nothing happens on reboot.
Another popular advice is that you should edit the build.prop and add
net.tethering.noprovisioning=true
But that fails too.
It's embarrassing that I have a rooted and unlocked phone, but I can not use my phone as a hotspot. I have tried a few apps as well. They fail.
The hotspot option never appears on my Settings.
Does anybody have a solution?

When you say unlocked are you saying that it has the U firmware installed? I believe the U firmware allows hotspot natively.
U firmware
Thank you for replying come up but I do not know what U firmware is. I assume it's a generic firmware for the S7.
My phone was a Sprint phone. It has the model number SM-G935P.
I had a professional root and unlock it. It had the hotspot feature available and I used it. However, about a month later, the phone got into a boot loop, so I had to wipe the phone and restore it. In the process of doing that, the phone lost rooting (but it remained unlocked). I restored the root myself, but was unable to restore the hotspot feature.
I would rather not install another firmware. I am in Africa, and downloading two gigabytes is a real pain. Moreover, I'm worried that it won't work on my S7. Since my phone is rooted and unlocked, it seems that it should not be that hard to make the hotspot feature available, especially since it was available earlier with the same firmware that I used to have. Ideas?

Well if you don't want to go with downloading the firmware then the easiest would be using the app FoxFi. But I believe that if you download and flash the U firmware that it will stay, even after a factory reset. But it's up to you.
Foxfi
Thank you for your advice. I tried the foxfi app and it did not work. Although I could see the network that it creates and apparently connect to it, it would not issue an IP address. So ultimately my other devices could not connect at all.
I really don't want to install a new firmware. I'm worried that it will brick the phone. Are you sure that is compatible with my model of the S7? Where would I obtain the U firmware?
I'm just surprised and a bit stunned that there's not a relatively easy way to reveal the hotspot feature when the phone is rooted and unlocked. I would think that with all the bright developers on this forum, there would be a straightforward solution.
I appreciate your help.

As long as you have the US's Sprint Galaxy with the snapdragon processor then you can flash the U firmware with no problem. Look in the Sprint section for directions, you'll even get updates directly from Samsung and not Sprint anymore. And I know there is a way for Verizon when rooted to get hotspot to work but not sure if it would be the same for Sprint. If that's what you're going for then check the Sprint forums for that as well.
According to this....
http://forum.xda-developers.com/sprint-galaxy-s7/help/bloat-free-firmware-930u-tried-t3428974
It only qorks with 930 models. Mine is SM-G935P.
That same thread says " You cannot root this firmware with the Sprint model. "
So I'm still stuck.
I just don't understand why there isn't a simple way to turn on this feature when the phone is rooted.

Are you sure it's rooted? You said you did a factory reset, so unless you rooted it again then you have lost root. And you were looking at the wrong forum, you need to look on the Sprint S7 Edge forum (S7 is the G930 and S7 Edge is the G935) for what you need to do.
you are right. When I reset it, I lost the root. It remained unlocked, for some reason.
However, I was able to root it again by myself. The only thing that I lost was the hotspot.
I'll try another forum here. Thanks!
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

Since i switched to metro pcs ......my sim service is not active

Hey guys,
I have an S8+ from Canada (unlocked, purchased direct from Samsung). The latest update seems to have killed off the ability to get data working, everything else is fine.
The update went as normal, but as soon as it rebooted it was out of action. I've since reconfigured APN settings, wiped the cache partition, reset the network and performed a factory reset - no dice.
I swapped sim cards with another GS8 - my sim worked fine in the other phone and that sim didn't work in mine.
Anyone have any ideas?
Kind Regards,
Michael

Is your APN settings still intact after the update? Check under settings>mobile network>access point names. That's most likely the problem, you might have to Google the APN for your current carrier and add it to your APN list, then select it. If that isn't the problem make sure you have the proper network mode selected (ex. CDMA, LTE, Global,...) if you need further help don't hesitate to ask.

Thanks for the reply - yea that was the very first thing I checked. No dice!
Do you have the proper network type selected for your carrier?
