Hi,
I purchased HTC Touch Pro (US Cellular CDMA). I want to use it with Mumbai MTNL Garuda Mobile Phone service in Mumbai, India.
I don't know much of cell phone flashing and reading web pages would like to get this done.
1) How do I check my phone needs what ROM and which one is it already using ? I assume ROM is like BIOS and windows mobile is like win xp os. So installing ROM will not affect windows mobile. do I have to flash rom for a specific carrier\service provider ?
2) How do I check whether my phone in unlocked since this is CDMA and has no sim card ? In ebay ad said it was unlocked.
3) How do I find roms for "mumbai garuda mtnl". You can google the quoted string for information on service provider. I don't see much helpful info on site and the service provider is not helping. It is open to questions if I have any so let me know if you want me to ask them. can one check compatibility between US cellular and MTNL garuda mobile cdma network so I know I can use the phone.
4) Please enumerate high level steps with some pointers for me to follow through the install process.
5) is the handset supporting 3G since I see its network specs as:
Network US cellular:
Dual-band (800/1900MHz), CDMA2000 1xEVDO Rev. A/1xRTT and IS-95A/B voice or data with up to 1.8 Mbps up-link and 3.1 Mbps down-link
MTNL Garuda mobile network is CDMA-1x. Another MTNL 3G Jadoo is 3G (WCDMA, HSDPA).
so compatibility wise can I use the US cellular handset on MTNL ?
CDDMA-1x and CDMA2000 1xRTT are same so I suppose handset should be usable.
6) when switching carrier is it simple as registering your new handset with new carrier ? is there standard process for it like call in their network using some special number and type in your existing number which you have with their network. ex. if I have 20337444 number on MTNL network then on HTC Touch Pro I dial in some special number for MTNL network and then key in my existing 20337444. This will register the ESN on their network and I am all set.
7) the MTNL guy said that first check if dialing *228 gives you MTNL network. If so then go to customer service and get more help. When I dail I don't think it does any thing. It gives 3 beeps and returns to home screen.
Additional info MTNL gave was they use channels primary 185 and secondary 226. I am not sure what these channels mean.
Regards,
i dont beleive you have to flash any specific rom to get your carrier to work, but you will have to google for "carrier cabs" + your provider name to find what will work for you
to see if your phone is unlocked take the back off the phone, pull the battery, and then put the battery back in, hold the volume down button and press power till the phone turns on, i beleive it will say something like "security unlocked" if the phone is unlocked, after you check that just pull the battery and put it back in once again and start up your phone to get back into windows mobile(not holding the volume down button this time)
as far as roms for the mtnl garuda, any rom will work, i reccommend the energyrom, google energyroms.com, cdma seems to be cdma anywhere you are, if it says cdma it should work in theory
your handset will support 3g, the us cellular version of touch pro supports 3g
for the mtnl garuda carrier to support your phone, you will have to see if they will accept your meid or esn under the battery, here in the USA verizon wont accept sprint esns, and vice versa
sorry i cant be more helpful, but hopefully somewhere through this i have helped you, good luck!

thanks for reply. I searched for "carrier cabs mtnl garuda" but no good results.
I learned from specs the model is RAHP800. does it mean that it will not work on MTNL garuda ?
MTNL garuda CDMA carrier cabs
Hi,
can some one provide carrier cabs for MTNL garuda CDMA (no RUIM) along with install instructions. would be nice if you have activation instructions. how do I get *228 to connect me to MTNL network ?
a touch pro 800 is the sprint cdma touch pro, and about the cabs sorry man i have no idea, usually when i call boost mobile to activate a new phone i provide them with my numbers from underneath the battery, and they will give me the msl code to enter epst and change the msid and mdn, maybe you could call your carrier and ask for the msid and mdn? as far as getting your msl code, as long as you have the microsoft .net cf 3.5 cab installed on your phone you can use a program called "baf msl grabber" to get that code
good luck, hope you figure something out, and if you need anything else feel free to contact me
Do you know anyone else with a TP runnon that same network? Maybe you can get some files from their phone.
the terms you used are new to me like "msl code to enter epst and change the msid and mdn".
You state "msl code to enter epst and change the msid and mdn," and use "baf msl grabber" to get that code. The MTNL garuda mumbai service folks I talked to are not willing to give any details. They in fact are just not supporting any handset other than what they provide. Now they are discontinuing new cdma handsets which are not using RUIM card (they say its similar to sim card).
can you guide me to some article which has instructions and explanation of various steps we might take to get things done like ones we have on eHow.com.

I do not know of any such user. can you guide me to simple article which expalins the steps involved in doing any programming / install of cabs etc. I have not much idea about cdma programming.
Regards,
Installing carrier cabs and flashing roms wont make the phone work on the network you want it to. The first thing you need is to change the PRL on the device to one that works with your carrier. This a file file you may be able to download, or get it from someone elses phone who uses the same carrier. After that, you will need to program all your info into it, MDN, ect. Then hopefully your carrier will even allow the ESN on their network. Did you say this was a US Cellular device?
Hi,
I learned from service provider that need to disable PRL and then use programming code so can feed in information. So for US Cellular HTC Touch PRO CDMA (no sim/ruim) can one provide programming code\dial codes ?
Do I need activation code in order to be able to enter into programming mode ?
Here is some reference for it: http://support.sprint.com/support/a...e-vw371511-20090807-140419?&INTNAV=SU:DP:HDIB
I would like to program my phone and when I dial ##778# and make a call it just ends. I am not sure how to enter the progam mode. Please guide.
There isn't a master list or anything like that. I used to flash phones to cricket and the 2 TPs I've flashed from us cellular were problematic. Could have been a coincidence. You need to obtain the PRL.

HTC Touch Pro unlock and program code
Hi,
I dialed ##000000 and it now put me into EPST (Activation Wizard(MSL)) screen. I guess I have made some progress and I see MDN, MSID, Home SID/NID #1.
It seems all sprint code listed here http://www.pcoperative.com/ppc/htc_tp_dial_codes.htm
works just that no need to key in ending # for each code.
Well how to check that phone is unlocked. I dialed ##775 to update PRL and it prompted me for unlock code.
I purchased phone from ebay and the ad mentioned that its unlocked.
is unlock code same as SPC/MSL unlock code ?
I went into bootloader and it shows Security Unlocked.
Why does it prompt me for unlock code when I go to ##775 to update PRL ? what to do so I can disable PRL ?
Few other codes like ##DEBUG and Advanced EPST show me information fine without prompting for any unlock code.
Regards,
You haven't made any progress at all unfortunately, you still need the prl. Any codes you enter that allow you to MODIFY phone settings will require an unlock code.

I installed the ZV8 L update via TWRP to mantain root.
At the same time I proceeded to use the GSM unlock method by changing the build.prop from SPR to either spr, ATT, TMO, VZW, KDDI, and other carriers that are in the hidden menu to no avail. Each time the setting menu would change to the carrier selected.
I decided to try the carrier unlock via the "carrier folder copy method" found here on XDA. After doing the mod, the phone was working on GSM without a hickup, so I can confirm it does unlock the GSM part, also, I did a network scan, it detected ATT and conected to ATT. I DID NOT try to make a test call. (I am from south of the border (Mexico) but live in a border town, I pick up US carriers because of the proximity to the US) Today I traveled to the US, but was so busy with other things, that I totally forgot to see it the phone would connect to ATT, since ATT is my service provider when I roam in the US.
Just as I was going in to Mexico I remembered about the phone, got it, and noticed that in the carrier it said "LG" instead of the usual ATT carrier when I roam. I tried to do a call, but a recording I have never heard before said that my account was not configured for this type of call.
By then I was in Mexico, and could not do any more tests. I reset the phone, and it picked up my mexican carrier without a problem.
I decided to do the NV/RUIM trick from this post..... http://forum.xda-developers.com/sprint-lg-g3/general/unlock-sprint-ls990-cdma-carrier-t2985523
After the mod, my phone rebooted with no service. Right before the reboot, I pulled the battery and placed my nano VZW sim in.
After that I went ahead and modified the build.prop and changed the carrier from SPR to VZW. Did a reboot and when the phone came on I got a couple of UI crashes and hiddenmenu crashes. I went to the mobile settings and changed the phone to Global, and, in shortcut master I changed the network setting to CDMA/LTE/EVdo. A few seconds later, I got signal bars and went ahead to make a test call........at first I got a busy signal, decided to make another test call....
Call went though. Voice was perfect without issues.
Random UI and HiddenMenu crashes, but call go in and out.
In the carrier I get "Partial Service Functionality"
These tests have been carried out in MEXICO, while I am roaming with the mexican carrier, I am not in the US and cannot test the call features, SMS, and/or LTE.
Any one out there in the US would like to test this out?
Also, any coder out there able to figure out how to fix the random UI and hidden menu crashes?
If I flash a Verizon Baseband to the phone, will I brick the phone?
Will I still be able to boot the phone to TWRP to reflash a Sprint BB?
Would a guide of what I did be necesary?
Too soon to post a link for beer donations, or is this something that has/is been done?
UPDATE: I dialed *228 and pop up came up (2nd picture)
Reserved.... who knows.
I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.
Locate and select Wireless & Networks or More Networks.
Select Mobile Networks.
Select Access Point Names.
Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
Program each field using the settings below.
Save the changes to return to the APNs menu and select the new APN.
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC
MMS proxy
MMS port
MCC 310
MNC 410
Authentication Type None
APN type default
APN protocol IPv4
Bearer Unspecified
Note: If you are unable to program your device following the steps above, refer to your user manual or contact the manufacturer for assistance."

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.
So a little background on why I'm posting this. I have owned a G4 G5 G6 and V20, all on Sprint, and none of these devices can ever access the Phone Info section or "Radio Info" section as it's referred to on the Hidden Settings shortcutter App. I believe Sprint or LG removes access to this area on all LG devices. On all of the ones I've owned I can try and access the section but only catch a brief glimpse of it when I try to access using a shortcut app. It is always immediately covered by the same message every time which is: Note This application does not work on this device.
Now I just activated a V30+ a couple weeks ago which I received through Sprint's normal telesales channel and on this device I can get to and modify most fields in the section. I haven't seen other people posting about this so maybe it's standard for everyone with the LS998 Sprint variant and no one really cares or just doesn't have anything to say about it. If thats the case, my apologies for wasting everyones time with an unnecessary post .
If my access to this area is a one off situation and could help lead any developers or more avid tinkerers to any discoveries I'd be happy to test out some things together with anyone with more experience than myself. I've been holding off on attempting to unlock the bootloader and haven't done any PRL updates or resets just in case this access is worthwhile as I've been worried something is going to update and take away my ability to get into the section.
I've included some screenshots. I've cropped them to try and remove some of the more personal data but I think all the relevant sections are covered.
*** Below are some questions and thoughts I've had. I hiding the section it to keep things less cluttered for those that are just reading up but dont have any experience or opinion on the settings/functionality etc***
If everyone can already get to this section, have you changed your bands or modified any of the settings and what results did you see?? I've been tempted to switch up some settings and run some tests but I'm being kinda chicken about changing anything because I can't find any info on people using this menu to do anything except screw up their coverage. A few example seems to be people on different earlier LG models that select USA but live outside the US and then cant get it back to their countries settings.
Here is a list of things I would like to examine more, or try out in these menus. Maybe some of you have already done such or have the same questions. Any feedback would be cool on any of these things or even warnings or endorsements. I would love to learn a bit more about this area and its possibilities.
Under the "Set Preffered Network Type" option I would like to change the current setting of LTE/CDMA/UMTS auto (PRL) to one of the other options and see what happens. I believe this area is relatively safe and can be switched back to the original setting easily. I'd like to switch to Global Auto Mode, Unknown Mode, GSM Auto mode and LTE Only Mode and run some speed tests and see what towers its connecting to in each.
There are four toggle switches, one of which is grayed out. This is the Video Calling Provisioned Switch. Curious if this would possibly become accessible in another mode, or if there was something i could change in a database editor that would allow me to switch this to "on".
The only setting I did change was the one DNS Check. It was originally set to disallowed and I switched it to allowed. I dont really know what changes or abilities this added or took away and have not seen any difference since doing so.
The SMSC when Refreshed will give me an 11 digit number in "" followed by a 3 digit number. It begins with +1 giving it the appearance of a phone number. I believe this has to do with SMS provisioning but am unsure and have not modified the info here.
One part I am very curious about is a grayed out button labeled OEM-specific info/Settings. I have searched like crazy just to try and find some info on whats behind that button and got nada.
In the additional menu section (the three dots) I have an option to Select Radio Band. When Pressed it takes me to a menu which sats "set GSM/UMTS band". This is the area I have found little about other than what I mentioned earlier about people getting locked out of their country settings. I have not touched this setting.
The IMS service Status of my device seems to not populate correctly as I'm listed as not registered or unavailable for all sections as seen in the picture attached. I could swear that a week ago I was showing "registered" but if so thats no longer the case.
Thanks in advance for any feedback.

Do you mean the ones within thd expanded part of the phone info section? If so, I've checked those out and they are blank. Screenshots attached.
So enough people have seen this post now that someone with a V30+ should be able to confirm whether or not others can get to these settings.
Anyone?
There is several other threads about this already. I found them while trying to find a way to get more ?? bands working on my India based phone. Nothing new i don't think and none of it actually helped, for me at least. There is a dialer code for it but i can't remember it.

I'd like to hear what you tried out and see what changed and what stuck and what didn't. . Maybe we can get your phone working better here in the states if we team up on the problem... I know my avatar shows I'm a junior member but that's because I don't really post often, but I do plenty of reading and tinkering myself and I have been in the Telecom business for about 15 years. I'm not an expert or making any guarantees but I certainly don't mind helping out a fellow member here if I can.
Do you have your MSL code? I have mine so if you have yours maybe we can take a look at how my phone is provisioned in the ##data# menu and get your bands setup the same way since mine should already be configured to the proper bands for the U.S. Between modifying that area and making some changes in the Radio info section that could do the trick for you. Let me know if you'd like to work on it and we could PM or you could reply with a run down of what you've tried and how you're setup now and we could go from there.
Cheers.
*#546368#*930#
Field test. LTE band selection. Selecting any band from the menu just makes it completely lose cell signal. After selecting a band it just either says success or fail.

Ok so that dialer code doesn't trigger anythibg on my model. I also tried replacing 930 with 998 and tried replacing the *# and #* with just ## and no luck. But no worries.
I'm thinking you may need to change your settings in two menus in order for the new settings to work together. If you go into your Data menu (##data# or maybe *#data#* on your model) and update the information there to match the ones I am attaching in my screenshots and then go into the Radio Info menu and select a similar setup to how my device is provisioned you may see some success.
Thoughts?
You would need your MSL code in order to change the settings in the ##data settings....
Where do i get msl code?
Neither of the data dialer codes are working for me.
Oh those settings are only for cdma phone?

There are a bunch of tips and tricks to find your MSL code posted throughout the boards, but I have only ever got mine from the carrier. If you call customer service you can usually talk them into giving it to you, though their policy on this is to not give it out unless your phone is fully paid for / out of contract. If you tell them you are working with a tech in a store and need it for provisioning they will normally give it to you.

I know this may not be in the right place but does anyone know how to bypass frp lock on this phone
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!

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

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 ?
