Hi,
I am from Bulgaria and I bought a ATT locked SAMSUNG GALAXY S5(SAMSUNG-SM-G900A) from a friend.
At first wasn't able to use my Bulgarian sim card(operator : M-Tel) but then I paid for unlocking code and 5 days later I unlocked my phone.
I put the card into the slot and started the phone. The signal bar was showing full but I was unable to make calls or send messages because of "Not registered on network" message. After an hour of reading the internet I found this code *#*#4636#*#* and then went to "Device Information" and on "Network type I change" it to "GSM only". ( I used the code because in the menu I dont have "Network type" option).
However now I can only connect to GSM network which is the problem because my mobile data is only EDGE NOT 3G. Here I need your help of solving this.
The available option of "Network Mode" are as fallows:
WCDMA prefered
GSM only
WCDMA only
GSM auto(PRL)
CDMA auto(PRL)
CDMA only
EvDo only
GSM/CDMA auto(PRL)
LTE/CDMA auto(PRL)
LTE/GSM auto(PRL)
LTE/GSM/CDMA auto (PRL)
LTE only
Unknown
There isn't LTE network in Bulgaria so I am asking how to use 3G on the phone. Should I root it(not pretty sure how to do it) or something else?
I posted my question in Bulgarian android forum and one guy told me to switch to WCDMA prefered but when I do and try to connect the operator M-tel it says Unable to connect.
So thats my problem with the Samsung phone so I would be very happy if someone knows how to fix this and help me.
Cheers!

1. WCDMA only
2. Manually register to your Network by Settings [Settings>More Networks>Mobile Networks>Network operarors]

Just call your service provider and ask them to activate 3G......I had the same problem, they solved it.
I called the operator today and they told me that other user also complain about their newest models of Samsung brought from USA and it's a software problem and to check for a software update. This didn't sound like a good news. Any ideas? Or i should just wait for something to happen.
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

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?
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

Thank you I followed the link and instructions and I have hd calling now. And i use Google dialer and contacts and everything works!

hello!
I am trying to set my network mode to WCDMA because I want to use data and receive calls on the same time since my carrier hasn't enabled VoLTE (that's another story...) but I can't!
The option is there, settings, more, Mobile networks, network mode, i make the change to "GSM/WDSMA auto" but it won't stick! If I go back and come again to this menu, the option is reverted back to "GSM/WDSMA/LTE auto"!
There is no luck either with the LG hidden menu, *#546368#*870# , it says "Connection problem or invalid MMI code".
Could this has to do with my modded kernel?
Any other ideas?
Here is my setup right now:
LG G6 H870
Android 7 Nougat V11i-EUR-XX
Melina kernel 3.18.62-melina-rel7_2017.12.31_uber-6.x_STOCK_zefie
Thank you in advance for your help!
That is a GSM phone. You cannot simply switch to CDMA. Different hardware.

what?
If i know that correct, WCDMA = 3g, right?
I want my device to be locked to 3g only, not 4g, because when I receive a call, it drops from 4g to 3g and I lose my internet connection, which is really frustrating if you are in the middle of a video call!
