We really need to get through to Asus that we need an update to enable VoLTE on TMobile USA soon or our phones are useless.
Some people might have a critical need to make a call and they'll find they can't!
Yes even WiFi calling features is missing.
Used 2 Sim Cards (SIM 1 & SIM 2)
Settings , then Network & Internet , then SIM Card at the bottom " Use mobile data for VoLTE Calls via..." turn it on . My calls have been working fine .

Tried this. Not getting VoLTE calls on TMobile USA. It still goes down to 3G to make the call. Not January yet so yes calls are currently working on 3G. But this seems as if it will end comes January. I hope ASUS can bring us an update soon so VoLTE will work on TMobile USA.

Hie Guys first of all i wanna thank u all for sharing ur valuable suggestions with other which cud b life saving for many.Actually i am using lg d855 32gb 4g in India it does not support volte function in indian band so is there any way to turn my g3 into volte
Thanks in advance
I have the same problem and I have searched everywhere to find a solution. I don't think you can enable it by yourself. The phone requires an update by LG to support VoLTE with Indian carriers.

This must be for JIO. I havent tried but have same device D855 32GB Not sure this will work. this is same as suggested for Tmobile too. Site says it has VoLTE RCS http://www.lg.com/in/mobile-phones/lg-G3-D855-32-GB but JIO supports LG G4 onwards. Maybe this will work.
There is a hidden menu. Am on Android 6 so dont know about 5. I see Airtel dropping to H when I call. Tried this and it stayed in 4G but call did not go through. So looks like it tried VoLTE and it did not work. Airplane mode ON and OFF got me back
Anyway try this
call
*#546368#*855# opens hidden settings
go to Modem Protocol in that list
Select VoLTE Radio NV On/Off and set it ON. Device will reboot. {This is where I lost my ability to make calls on Airtel. But data worked fine}
Tell me if it works on JIO. Also I am not sure they would give the free SIM with G3. Anyway try ur luck

Nope... its not working.... calls going blank when VoLTE Radio on from hidden menu... no solution I think for us from LG...
We can just make HD calls over LTE using Reliance's its own app called JioOnline which calls over data using LTE.
I heard the SIM is per IMEI code. Is that fine ? As again http://gadgets.ndtv.com/mobiles/fea...les-that-will-work-on-the-jio-network-1454171 says it should work.
Does it work with their apps ?
Does anyone got the solution ... ??
Hi guys,
Did anyone here notice that when you have an active call which is on loudspeaker, you cant browse the web with your mobile data! I am hoping this is a setting which i can disable / enable to allow me to browse the web with my mobile data when currently on a phone call with someone.
Quite annoying and i am not sure if its a bug or a settings.
Would appreciate it if someone can shed some light
Thanks!

The same to me. But i know it isn't because of the phone or miui. If your carrier doesn't support VoLTE, the phone will temporary be disconnected 4G during calls.
Search VoLTE in question and answer forum
Hey guys,
Doing tests it seems to be a bug.. I have 2 Sims in my phone, if I get a call on SIM 2 which I use for receiving calls (this has no mobile data) and I try to browse the web it does not work, my SIM 1 is the SIM I use for browsing the web with mobile data because I got unlimited data on that SIM. It seems that when on a call with SIM 2 and I try browse it is using SIM 2 for the browsing (but this fails because I got no data to use on SIM 2). If I get a call on my SIM 1, I can browse the web successfully while on the call! So it seems to be a setting or a bug or something to that effect? Nothing to do with volte etc.
Any ideas?
I rang my operators and they all allow for browsing and phone calls.. doing standard tests the above is what I got. So it seems to be a dual SIM issue or something?

Looks like the SIM you're making the calls from doesn't support VoLTE or doesn't have it enabled. Without it the phone will drop to 3G when making calls and you won't have data.
Are you using the 8/128 Chinese version in the US? Is the 4g LTE connectivity good ? I' d like to purchase the Chinese version since it has more RAM and use it with t-mobile but I see that the international version supports a few more bands but only comes with 6 GB of RAM.
I live in ireland, i have the 8GB ram china rom version. Now running eu rom.
See even if 4g goes i can use mobile data with 3g?
If i purchase mobile data for sim 1, i can browse the web and have a call and vice Versa with sim 2.. i dont think its todo with volte, i think its because im on a call with like sim 2 and the phone doesnt no to use sim 1 for data?
I have the dual SIM. Was having a horrible experience on calls in the US, and I noticed device dropped to H from LTE as soon as I made a call, and wifi calling wasn't working.. Also got v choppy data.
I spoke to ATT and it took a while but I explained the issue, gave them ONE IMEI only, and asked them to register it so I could get VOLTE and wifi calling.
It took 2 weeks to get a response. I just got an email saying they had resolved the issue. Meantime NO CHANGE in my service ...
...Until ...
I put my sim in an iPhone and registered for WIFI calling. That was the missing link, the thing that I couldn't do on my Note 10! Get it to register the way ATT likes it.
Once I got the confirmation on the iPhone, I put the sim back in my note 10 and now I have VOLTE, WIFI calling and my data speed has improved significantly.
So it's fixed.
(BTW I did a speed test and iPhone still consistently got better data speed, but that is probably because the F doesn't have band30)
I hope this helps someone out there!

Thank you ever so much! I had to go a slightly different way, but I got Volte working.
First, I had to call the nice ATT Agents a couple of times. I finally got hold of an agent that knew how to do this. Even though I previously had an international Note 8 working, the ATT system had the IMEI of the new Note 10 plus.
I gave her an IMEI of a real AT&T Branded Samsung Note 8 I no longer used and she pushed it into the AT&T Systems for me.
I did not have a Iphone to activate WiFi calling on, but I then stuck the SIM into an old Note 8 that had previously worked with Volte but would not anymore. After booting, I was again able to active wifi calling. That seems to be the key.
I moved the SIM back to the 975F which was still configured on SIN (Singapore). For some reason, the Camera on phone contacts were no longer present! ARGH!!!!!!!!!!!!! It was previously present on contacts which indicated that Volte was not working. I changed the CSC to BTU where it also showed up and rebooted. Not joy - no Volte
So I extracted the ATT CSC file from CSC_OMC_OYN_N975UOYN2ASJ8_CL16989516_QB26837495_REV00_user_low_ship_MULTI_CERT.tar.md5. I then ran it through lz4.exe to uncompress it, and SVAImgUnpack to unpack it, and was able to access the contents using ext2explorer.exe
I copied the OMC directory from that partition to the SD card of the phone.
On the phone, I then used Total Commander to copy the omc/single/ATT directory directly to /product/omc/single/ATT - just that one CSC.
Then then copied the /efs/imei/mps_code.dat to the SD card. I then edited the SD card copy of mps_code.dat and change the content to just the three characters ATT. I then copied the file back from the SD card to /efs/imei.
Reboot, and walla! Volte worked (the camera showed up under contacts that have Volte cabability. Wifi-calling then appeared under settings. I was able to enable wifi calling on the 975F perfectly.
All good!
I hope this may help other ATT customers.
@ekerbuddyeker, Do you still using ATT network with N975F (Note 10 International model) ?
My company HQ in USA, so I frequently contacting to US HQ guys with ATT Wifi calling. (using Google Pixel 3)
I've Note8 International(N950F) model and I want to ATT Wifi calling via this Note8 device.
I checked that this Note8 / Android9 support T-mobile US and another many Carreir/country(Vodafone, Beeline-Russia) wifi calling enabled by this phone.
If your N975F has still VoLTE and VOWIFI works smoothly on the ATT netowrk , Can you share the screenshot of ATT's VoLTE and VOWIFI working?
Your guide saying, First Wifi calling provision on the iPhone then put the SIM back to Samung Galaxy device,
I followed your direction, But no luck.
*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!
Same problem
I'm having the same problem. Any progress on this?
I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.
Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.
I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.
What's the correct service menu number for our phones?

Realme Gt Master Edition VoWifi dont work?

it depend on your sim card carrier
I have been looking for that information, thinking about getting this phone to use T-Mobile USA GSM voLTE? is this phone compatible?
@ryantek No, it's not. I have been using Gt Master in Mint Mobile (which is T-Mobile MVNO) for 6 month and no VoLTE, no VoWifi. I could use mobile data, but even this was not very good, often gets stuck to 3g network, though GT Master supports most of the LTE bands used by T-Mobile (except for B71 600Mhz).
I had two long chats with Mint Mobile customer service, no resolution.
I believe it's gonna be even harder to activate it after July 1st, when T-Mobile will shutdown it's 3G network. Mint Mobile didn't make me any problems to buy and activate service, but now constantly bugs me to replace phone for compatible with their network.
I've also tried it with US Mobile (T-Mobile network), Boost Mobile (ATT) and couple others. The same effect.
Save yourself some trouble and buy phone that's on compatibility list: Oneplus, iPhone, Samsung or Motorola.
I bought Galaxy S22 and now use it as my main device in Google FI. GT Master still have active Mint Mobile simcard until 3rd of June, but after that it will be over.
Hi,
Thank you for sharing all of this information. It is sad to see the carriers in the USA do not support this phone. Sadly I will stay away until anyone can confirm a phone of this brand that works with VoLTE (Tmobile).
Once again Thank you.

Set up VoLTE and VoWiFi via QPST and the ( advaced pdc tool PDC ) Root is required. This option works in stock. You need to try several "choose" profiles, one will definitely go
In custom rom, if it doesn't work, just back up the EFS partition (after editing in stock rom) and restore it later in custom rom
I see. Wondering is there is a signed ROM with VolLTE enable out of the box.
Today I tried Google Fi simcard with my Realme GT Master (normal not modified ROM) and it worked!! VoLTE is working and so is VoWiFI (I think). I'm not 100% sure about VoWifi. I have icon of VoWifi during call but I can't make call just on WiFi while on Airplane Mode, I have to turn off Airplane Mode or it doesn't allow me to make a call.
Google Fi was activated with Galaxy S22 few months ago.
I'm not gonna test it for long, because I use Galaxy S22 as my main device now and in few days I'll move to US Mobile/Verizon, but Google Fi is usable. I still can't recommend buying GT Master for US: too much hassle, too many unknowns.

so basically you don't know which network you were on while VoLTE started to work? Google FI uses all three networks and switches them dynamically
As far as I know Google Fi uses two networks: Tmobile and Us Cellular. As I'm in western Massachusetts and US Cellular doesn't have coverage here, I'm pretty sure I got connected to T-Mobile. But I can't confirm it with 100% certainty.
