I'm having the same issue, running G930AUCU4BQA6 on a 930V. Using the code they gave you, I see Set Preferred Network Type is "WCDMA preferred" no matter what I select there, it always reverts back to "WCDMA preferred." I don't see anywhere else to make that setting.
Anyone have any clues?

[Q] Tried to connect to LTE went back and super slow now

Hey my friend wanted me to check if I had LTE in my area so i did the *#*#4636#*#* and clicked LTE/GSM/CDMA and did a speed test. Clearly I didn't have LTE testing myspeeds like (.12mpsD 1.2mpsU). Im curious as to if I accidently caused somthing to get screwed up in that section and would a full restore to stock fix that issue.

AT&T I assume (since you bothered to try at all).
Did you change your APN settings? Did you change the setting BACK TO WCDMA preferred?

Best you can do is go back and change it to stock (WCDMA preferred I believe)
Also make sure your APN is set correctly. Speed test via AT&T's cingular proxy are throttled. Read through this thread http://forum.xda-developers.com/showthread.php?t=2021401

I didn't get around to changing my apn settings I kinda got scared and went back to WCDMA all my APNs stayed the same. What does changing that do is it specific to the radio I assume? Idk what part of the rom I actually affected by changing to LTE

You weren't going to get LTE without changing to an LTE-enabled APN (for AT&T, it's "PTA" instead of "PHONE" or "WAP.CINGULAR"), so I assumed you had changed it.
Double check to make sure you're on WCDMA preferred ('ve had it not "stick" on phones before"). Then, restart your device.

Figured that much. I did a full stock restore and I have the same speeds for some reason and im on WCDMA preferred...im starting to think maybe the carrirer capped my data or something would it rele be that low tho (ping 135ms Download 122kbps Upload Network Communication Failure)

[Q] SM-G900i with ATT network

I got an international version SM-G900i from Amazon. I have an ATT sim card. The text and phone calls work fine but I could not get any data roaming. Though from other posts I got the data roaming, I was not able to set onto the ATT 3G/2G network in the network operator selection. My network is always shown as Maritime. Does anybody know why this happens and ways to change it?
Thanks a lot.

Have you checked apn setting and made sure they are correct for ATT?

I tried configure the APN setting based on a link online for ATT APN. Now I am losing signals even for calls and texts....I think there might be other things that are wrong...
Error message for no ATT service
Tried different variety of ATT APN setting. Still could not get it to work....the phone shows a signal but gave me an error message that Selected network(AT&T) not available

I'm not sure what did you mean by "data roaming"??
Anyway, the problem for now is no network register. The APN settings will NOT affect at this step, so not not try to mess up with it right now.
Try to get into Settings > More networks > Mobile networks, and set Network mode to Auto connect, and Network operator > Select automatically.
That may help the device to register on the Home network.
Problem solved....or maybe not but it is working!

Okay. Thanks. I switched it back to the auto-selection mode. By data roaming....I mean 3G data. My phone is working now. I checked ATT billing usage report, it did not increase the data usage dramatically so I guess everything is fine.

Glad that your phone works now.
BTW "data roaming" and "3G data" are different things. "data roaming" is "3G data" when you are roaming to another network (not your home network).

[Q] Data issue on Shamu (TMo)

Since installing I've not been able to get LTE and I am frequently dropping data/losing service altogether. Getting this notification that states I am running into network restrictions? I will post a screen shot next time I see it.
Any help would be greatly appreciated.
Verify your APNs, verify the connection option is set to LTE preferred in settings, (more), cellular networks, preferred network type

Axon 7 on Verizon 4GLTE

Well I finally got the roaming "R" out of my notification bar and instead of just LTE it says 4GLTE now just like my previous phone (s5) on Verizon. Data, texts, mms, and calls all work. The problem is it doesn't stick after a reboot. After rebooting it's back to saying just LTE and the "R" is there. If anyone knows how to make it stick can you advise me please?
Have you disabled roaming itself?

I just tried that and i got no carrier label and no bars at all. In settings network is unknown, cell network type is unknown, cell network state disconnected. Service state says voice in service and data out of service.
And i just dialed *#*#4636#*#* and chose LTE/CDMA auto prl. Then swiped down my notification bar to enable and disable airplane mode to restart the radios and i have 4GLTE again. Changed the apn to VZW that i had on there i added. In settings everything is on and says Verizon.

I know that this "4G LTE" icon can occur when LTE-only mode is engaged...is it possible you had LTE only and were not connected to CDMA at all? I've had that occur in some fringe areas and I believe I temporarily had the "4G LTE" icon vs. just "LTE" in those cases...though it sounds like you had calling working so I'm guessing this may be a different scenario. Very strange though...

Yes that used to happen when my phone info was set on LTE/GSM/CDMA auto (PRL). But earlier today i changed it to LTE/CDMA auto (PRL) and everything works and the notification bar says 4GLTE. It stayed like that all this evening till i rebooted a few mins ago.
On the phone info page after you dial *#*#4636#*#* there's the 3 dot menu on the upper right side. On that there's an option to select radio band and when you hit it you get 3 options. USA band, band mode 6 and band mode 7. So i picked USA band and on the main page i set it to LTE/CDMA auto prl. I sent an mms to myself and it works and speed test readings is 9.84 dl and 0.91 up. I just can't make it stick after a reboot.

Data Roaming needs to be enabled in order for Verizon data service to work.
Ahh. Well, leave it to Verizon to be that way. I know going through dialer was a option but even with sprint in the past as CDMA on some older aosp ROMs, prl auto wasn't even a solution. Sometimes roaming was preferred instead of prl. So that's why I started with questioning that. If the data entry toggle makes a difference, hen I'm glad that's the solution and rather it be something you can fix on demand as opposed to it being permanent because of a carrier back end problem - - problem being in the community eyes.
Can I ask what APN you guys are using because whenever I do get LTE it says 4glte and also no service

Well i found out with these settings i couldn't access my voicemail. I had a voicemail notification and you can't use the #1 button because it's not supported, so i used *86. It would dial out and connect for a split second and cut off. And i tried multiple times pressing the #1 and *86 to get to my voicemail but couldn't. So back to the old settings with just LTE and the "R" on my notifications bar. Thank you for the help!

These are the APN settings. On the APN type i got 2 different versions from different websites. One says to put "dun" and the other says leave it out. And on bearer one says leave it as unspecified and the other put LTE. This is exactly what i have on mine.
Name: VZW
APN: VZWINTERNET
MMSC: http://mms.vtext.com/servlets/mms
MMS Port: 80
MCC: 311
MNC: 480
APN Type: default,dun,mms,supl
APN Protocol & APN Roaming Protocol: IPv4/IPv6
Bearer: Unspecified
everything else: None or Not Set
Quick note you have to add the above APN. With a vzw sim you can't add one so you have to borrow a gsm sim card either att or tmobile and put it in and add this and save it. Then put the vzw sim and you'll see the one you created. Check mark this APN and you'll be good to go.
Are you all able to use HD Voice & video calling with the native dialer on the Verizon network? Some phones have an option under settings called 'Advanced Calling'. This is where you can turn on HD Voice & Video Calling for Verizon.

Not sure about video calling, but HD Voice/VoLTE, yes. The one Verizon topic you didn't bump P) has screenshots & instructions from someone who is using VoLTE with the native MiFavor dialer: https://forum.xda-developers.com/axon-7/help/verizon-compatibility-t3420991/page41

Unlocked Sprint G6 on TMUS

Got through the Sprint process and had the G6 unlocked for TMUS. Got the APN set up. Issue is the phone is generally in 3G. I can see under the mobile networks settings, I have the following options:
Automatic (current setting)
CDMA/LTE (LTE yes, calling no)
CDMA
GSM/UMTS
Any idea if there is a way to get a GSM/LTE option. Newbie here, but the phone seems to have the right bands, just the CDMA centric Network settings.
Ideas?

Have you tried through the hidden menu
Can not get into the esecret menu. Get bad MMI
I tried to get into the secret menu to change the network setting, but when I try, I get a bad MMI message. I am using
<star>#546368#<star>993#
Was a Sprint model. (993)
Any ideas. I saw the secret menu on YouTube and it does seem to have the gsm/umts /lte setting I would need.
