Verizon V20 is GSM unlocked from the factory. Did you change the apn settings? Change network settings to GSM if automatic doesn't work?

Hi guys, last night I trade in my S6 for S7.
That guy told me the phone is sim unlocked, I just need to manually adding APN and it will work. I am too stupid not to try with my sim.
I am in Malaysia, S7 variant should be G930F, but it's G930V, I tried two different carriers with manually input APN but the signal icon still blank with a cross:crying:
Besides, whenever I change network mode, it will revert to Global.
I can't select network operator too.
Is there any method to get it works with my local carrier? Flash rom from G930V to G930U or change IMEI will works?
flash "u" rom marshamallow..

Flash the "U" unlocked firmware on it. Looks like the phone is locked to Verizon. I would strongly recommend against changing the IMEI because that can add a lot of unnecessary complications.

Can I flash official nougat rom?
Any additional step or modification needed?
I see there are many firmware for different CSC such as XAA, TMK and etc. Which one is cleanest and works better for GSM network?
Currently on Verizon Offiicial Nougat 7.0 G930VVRU4BQC5
phones out of country with other networks, and att USA since note 2 came out.
I currently have s7 too and it travelled with me out of country as well no problems, I get 4g in most places, if not 3g until I can get to fast WiFi.
Ur carrier data bands must not be matching or phones damaged, in my expert opinion.
Once u put other carriers sim u either request carrier to send u apn via text msg where u just open it and it gives u option to save it.
Or the Sim itself will/should have those settings in it. And upon inserting sim then going to where apns are added, u may be able to select it.
A quick Google of bands of ur network can tell u, but I'm optimistic only a very few bands are missing off g930v/g935v
Edit: Yes Verizon phones work on gsm in global mode
There is another option in there LTE/GSM/UMTS
U will have to experiment between global or the one above mentioned, does the trick for me all the time
Hello guys,
Im a bit desperate, when I try to enable mobile hotspot on my ATT Unlocked LG G6 (H871) it says auth failed and just won't share internet connection not thru wifi nor USB cable.
Please I will really appreciate your help, I need to work with my computer all the time using this function.
Thank you
If u have an att SIM card the function will work but if u have any other gsm SIM like straight talk the functions won't work as the OS is still essentially att's android.
What network are you using? Is it att or another one?
I recommend you check your phone's APN settings.
Hi .
I have bought a S8 locked to US Cellular on eBay, clean , not blacklisted and when I try a SIM card from my operator does not ask for unlock pin code and remains without registering on my network.
Does anyone know any website or any method to unlock It?
Many thanks in advance.

Does it have a unlock app in apps drawer or in settings. It may be unlocked. If ure sim works. WhT carrier you on.
Thanks for your answer.
I live in Portugal and I tried 2 different SIM cards. The phone shows in upper left screen the message "SIM blocked". I searched for an unlock app too but I can't find any like in T-Mobile phones I bought in the past.
US Cellular is a CDMA network provider whereas in Portugal you probably have only GSM networks.
I think you should look into this and investigate this issues as well.
Another info: I flashed with Odin with the latest USC official Rom from sammobile. Can be this the cause?
This is 950U version and therefore has the GSM frequencies as well.
Even if it was only cdma it would prompt to insert the network unlock code....
Any help?
WHen I put a sim card it appears a forbidden sign on the top, where I should see the network signal...

So Im looking for a way to enable native tethering on my phone and after a lot searching I flashed the G935U firmware. After flashing the G935U firmware on my G935V, my data stopped working. Call and text works fine but no data. It doesn't even show the 4G LTE symbol in status bar.
I am currently using Straight Talk BYOP.
Any help would be much appreciated and thank you!

Thats the crazy part! I cant edit it after flashing the U firmware. But the APN settings are the same from when it was still on the V firmware. Its just now the 4G LTE doesnt work. I downloaded some 4G enabler from the play store that took me to some hidden settings to change between GSM, CDMA, and about 12 other variants of similar nature. After doing so the only one that worked was the CDMA (prl) which activated 3G network. But LTE CDMA (prl) didnt work which was what it was on I think.

add a new APN with tour settings. emable it... and try global mode
Nope still no go...its not even showing 3G at the momemnt
I tried every apn/preferred network type combination and wasn't able to get anything better than 3G. So I just got done flashing the G935V firmware back and now 4G LTE is working. Anyway I can use hotspot on G935V firmware?
SOLVED!
So after contacting straight talk it seems my APN settings where to blame.
Upon opening the APN, I had to change APN from "vzwinternet" to "tracfone.vzwentp." Then save and make sure network mode was set to LTE/CDMA instead of global.
I noticed it returns to default "vzwinternet" after flashing any firmware thus making me have to put it back in. But that's no problem at all. Everything is currenly working and I now have tethering THANK YOU FOR THE HELP

G935V to G935U for AT&T
I have the Verizon S7 Edge G935V working on straight talk with their AT&T sim.
Had to change from CDMA to GSM then add the new APN settings.
The problem I have is the G935V doesn't have LTE band 17 which is used in my area.
My Nexus 5 with same sim using LTE Discovery app confirms band 17 but with S7 Edge G935V
I don't get it but a different connection and its very weak.
I would like to give this G935V to G935U a try. My S7 Edge G935V has Android 8.0
I have downloaded ODIN, Samsung S7 Edge drivers, and G935U w/Android 8.0 (AT&T) July 24, 2018
Has anyone done this recently on a G935V with Android 8.0 on it?
Will I get LTE band 17?
Do I loose any CDMA capabilities should I want to try it?
What's the down side of doing this?
How would I continue to get updates?
Thanks,
Ken
