Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
Opening *#*#4636#*#* Phone info shows, "This application does not work on this device
I'm trying to change to the LTE network which is not available in the Mobile Networks. My carrier is Freedom Mobile and I'm running Android 7.0, with the LG G5. Anyone know how to fix this, or if this something the Carrier did to the phone ?

Try this code *#546368#*phone model#
My phone model is RS988 so the code will look like this
*#546368#*988#
Use this menu to toggle the LTE network
1. Type *#546368#*model# ( *#LGMENU#*MODEL# )[MODEL eg. H850 - type 850]
2. Go to "Field test"
3. Go to "Modem Settings"
4. Go to "RAT selection"
5. Chose what You need:
- GSM / WCDMA / LTE auto
- LTE only
- LTE / WCDMA
- LTE / GSM
- GSM / WCDMA
- WCDMA only
- GSM only
After You chose option Your mobile data may turn off and on.
Sorry for my bad English.
I was able to force the phone on to LTE, but it won't switch back to LTE after making a call. It stays on 3G.
Hi, guys!
I'm trying to fox my LG G5, but seems nothing works... I bougth this refurbished device in USA last octuber. I used it in Venezuela with my venezuelan phone number perfectly until march 2019. Then, suddenly, my device stop working. Now, is unavailable to recognize any network, no matter what SIMcard I plugged in (My SIMCard works perfectly in other devices, BTW). So, I went to three differents suport services in Caracas, but anybody could did anything. Now, I'm trying with some codes that I find, but it didn't work either. Actually, my device couldn't recognize some of them... Can you help me, please? I'm desperate to fix my LG G5.
My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
Purchased a A10e sm-a102u from someone. It originally was a sprint variant. Seller said it worked on cricket. She had me and sprint 3 way call to tell me they unlocked it, and a dialer code removed sprint provisioning (splash screen?) Ended up still locked to sprint sims. I found a menu hack (changeCSC apk) via applying a theme to open carrier selection inside legal info menu. I tried switching it to XAA and XAS, which allowed it to recognize my Mint Mobile sim card. This also allowed APN editing. Now the phone works to call and mms over wifi only. No mobile network and it says emergency calls only.
The build number ends in -ATE5.
The default apns are t mobile
In download mode it says carrier- BST.
Its like its half unlocked?? What am i missing? My Mint sim works in a unlocked LGv20
I have two used LG G8x - G850QM (unlocked) and G850UM (Sprint unlocked).
I am on T-Mobile for years.
The G850QM on T-Mobile shows wifi-calling on the menu and it works.
The G850UM has no wifi-calling switch on the menu, just not there.
I installed WiFi Calling app from Widget7 from Play Store. The app seemed to bring out a hidden WiFi calling menu. And the WiFi calling works. I confirmed the WiFi calls on my T-Mobile bill portal.
Hope this can help
Does it do anything for Volte?

I used two different VoLTE Check app. Both indicated VoLTE ACTIVE.
I dai!ed *#*#4636#*#* to go into Diag menu. "Phobe Info" indicated that
VoLTE provisioned
Video Calling Provisioned
WiFi Calling Provisioned
EAB/Presence Provisioned
But all the "switches" were grayed out.
This is in my daiily driver LG G8X g850UM on T-Mobile.
I assumed VoLTE is working automatically.
Most people with tmobile on this phone have found that for calls the phone goes from 4g to 3g when making a call. You will only see this transition if you are looking at the 4g indicator while on the call.
The concern is when T-Mobile discontinues 3g next month then you will not be able to make phone calls.
If you dont mind you might take a look as you make a call and see if it stays on 4g.
I understand. I, with 4 LG phones on Tmobile, am in the same boat with a lot of people. And I have purchased more LG phones- 3 V40 , 1 G7 and 3 Q7+ before I learned about the network transition.
Tmobile did a piss poor job in explaining the 3G shutdown.
Today is 4/1, with my Sprint-unlocked LG G8X, I can make a call and the LTE indicator stayed on.
This is what Tmobile has announced.
As of March 31, 2022, Sprint’s older 3G (CDMA) network will be retired
As of June 30, 2022, Sprint’s LTE network will be retired
As of July 1, 2022, T-Mobile’s older 3G UMTS network will be retired
Also Tmobile has delayed Sprint 3G shutdown until May 30.
Downloaded app and enabled, but all my buttons are still greyed out and it definitely still goes to 3g during a call? Not sure why it is not working on my phone?
It has something to do with the combination of native ROM, TMobile or Sprint SIM card in use, provisioning of VoLTE, and the (T-Mobile) LTE channels supported in your phone. I have not figured everything out yet.
It will be a rough ride for me until July 1 when the transition is over.
Forget what I've posted. I f'ked up. I mixed up 2 models.
I just received a T-Mobile email telling me my daily driver G850UM does not have the Volte turned on.
I looked up Phone Info and found Volte Provisioned switch is off and grayed out. When I wrote the post on March 31 the Volte Provisioned switch was on but grayed out.
I swap SIm card to the G850QM phone, and the Volte Provisioned switch is visible and in ON position. Look like I need to switch phone near term. And then find a way to cross flash QM firmware onto UM model. Need research. Fvk T-Mobile and the other two for doing their fake 5G rollout.
Thank you Buontinh. Got Volte, WiFi calling and video calling on my LG G7X G850UM on 20P software.
Uploaded the modded abl_a to both _a and _b. Insert an active T-Mobile SIM card, got new TMobile bootup logo. Got the wifi-calling switch. Got into Phone Info and saw votle Provisioned, WiFi calling provisioned, and video calling provisioned. Grayed out however. I made a call to my landline and the 4G LTE light stayed on. I guess it is working.
Still on Android 10 however.
The most difficult part was to get the phone on EDL mode. Must have tried 20 times before getting the "dark screen" EDL mode, only to learn that a Qualcomm hs-usb qdloader 9008 driver was needed too.
So I followed the below directions from reddit and it worked great on my velvet. I did the same thing on my LG g8x with *#546368#*850# code and I now have Volte, however phone still drops to 3g when it makes a call any thoughts on how to fix that?
There is a way to force enable VoLTE on the "LG Velvet 4G Dual Sim" specifically your version which is the "LM-G910EMW".
By default the feature is disabled on this model variant for who knows why.
Follow the steps below: 1. Click on the "Phone" app and dial "##4636##" -If done correctly it'll automatically bring you to the "testing" settings menu.
Click on "Phone Information" -you should see a list of VoLTE settings however by default they are disabled and greyed out but don't worry there's a way to reactivate VoLTE. (You Will Come Back to this Menu later)
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
Go back to the "Phone" App and dial "#*462633*#910#" -This code is specific to the variant and will not work on other non LM-G910EMW Phones. Dialing this should bring up the "Hidden LG Menu"
Select Field Test>Universal Enabler>Create New Config -a menu with check boxes for VoLTE options appearing
Select the boxes as follows "VoLTE" "ViLTE" "VoWifi" "ViWifi" And finally hit "Confirm" -a prompt will appear stating "Vo Services Updated"
Immediately restart your phone to allow the settings to kick in
After your phone has restarted go into your Settings>Network & Internet>Mobile Networks -If done correctly the VoLTE option will now be unlocked and available.
Switch on the "VoLTE"
Now to double check that your phone now truly has VoLTE enabled, repeat steps 1-2. If done correctly the menu should now say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -if these 3 are all switched on then you have successfully force enabled VoLTE on your LG Velvet 4G Dual Sim LM-G910EMW, congratulations!

Hello, I sintalled the app and it leads to a LG look menu I never encoutered with a WiFi calling switch !
However, when I go back to the app, then press again the button to open the menu, the switch is disabled.
Any idea how to keep it active ?
