Do you have Tmobile and using beta 11? VoLTE should work for you per reports. Unless you're on ATT or something else.

Edit - just realized I was assuming you have the Zenfone 6 for some reason which obviously may not be the case.
[ASUS ROG Phone II Guides, News, & Discussion] happiboi:
Yea sorry not on Zenphone - utilised this method very successfully on my OnePlus 8 Pro previously on Android 10 but after updating to 11 --> no dice :(
[ASUS ROG Phone II Guides, News, & Discussion] Kalanyr:
OnePlus disabled the functions used for this in OxygenOS 11 (because they are a security risk, which to be fair is true). There are ways to work around this (which I can't link too due to insufficient posting but I'll PM you) but it's a bit of a pain.

Anyone Having issues with T-Mobile? I'm having issues, where I cant, receive calls and they go to VM some callers say its blank silence then VM some say it rings twice then goes to VM, yet it does not ring at all on my end. Although if I call them they get the call going out... for the past 3-4 weeks

I've been with T-Mobiles Backend team and have done just about everything, 2 new Sim Cards all settings, APN checked and correct, Roaming set to ON <<<( This setting helped a lot with the issue) but it still happens.

T- Mobile is claiming the device is not compatible because VoLTE is not compatible... We know it just needs to be enabled, I don't think it is the issue at all because if it was I wouldn't be able to call those numbers back after I get the VM notification, I now have the engineering team looking into the issue.

I'm on the Latest WW 2009.49, I updated because I was on A9 and I did each update in sequence.

The phone was working flawlessly 2-3 months ago with no issues when I was on the Grandfathered T Mobile One Plus plan, 3-4 weeks ago I moved to the Military Magenta Plus plan, This not receiving calls issue is throwing me for a loop.

Any help is appreciated
[ASUS ROG Phone II Guides, News, & Discussion] reg66:
Just reporting, I had every incoming call showing as 'unknown caller' even tho VoLTE is enabled on omni rom (UK EE network). Just letting others know this guide still works with custom roms - or at least it does with omni

Never had an issue losing Volte after doing an update before. But after updating to Version WW-17.0240.2012.65 I no longer had Volte or Vowifi on tmobile even though the update was supposed to enable it. Idk what happened but I followed the tutorial and was able to get it working again. Many thanks @HomerSp

Has anyone been able to enable VoLTE on the Realme X2 Pro using this method with T-mobile US?

I used the mi 9t MBN but it did not seem to work.
[ASUS ROG Phone II Guides, News, & Discussion] enkryptik:
Upgraded to Android 11 on zenfone 6 and now do not have VoLTE. Wifi calling works but doesn't show it's a wifi call anymore.

Unable to follow guide again as AsusVoLTE cannot detect that I'm rooted thus not allowing tools to work.

What a time to lose VoLTE which non VoLTE devices getting kicked off tmobile soon.

Anyways, thanks for the guide. Worked great when I had Android 10.

EDIT: I stand corrected. Was able to follow most of the guide again and acquired VoLTE and WIFI calling with icon (was missing icon before following guide but worked). Had to manually enable diag mode though since the app doesn't seem to work on Android 11 on zenfone 6 at least?

Anyways, thanks again for the great guide.

Once again, Tmobile zenfone 6 with volte no thanks to tmobile/asus.
[ASUS ROG Phone II Guides, News, & Discussion] bindassever:
Hi mate,

Any chance you can help me how you activated diag mode manually on your phone. I couldnot activate diag mode from my asus rog 3 as enable diag mode from asus volte app does nothing. I am desperately looking for this volte setup.

Please help.

This no longer works for AT&T (Red Pocket specifically) for me. It worked at one point, about 2 OTAs ago. Odd.
[ASUS ROG Phone II Guides, News, & Discussion] VIPLightning:
The AsusLTE app DOESN'T work anymore on Android 11 openbeta. So in order to get Diag mode up and running, you need to type this command line either on your phone running terminal or on your computer running adb Shell before proceeding to follow the instructions by the OP.

setprop sys.usb.config diag,adb

For example, I live in Israel and my carrier is called 'Cellcom'. What should I do? From where I pick up the file for this or how to config it.. I'm really stuck, please help.

[ASUS ROG Phone II Guides, News, & Discussion] astracd:
I just checked there is Cellcom under pixel 4 file

[ASUS ROG Phone II Guides, News, & Discussion] MeTaLishSnAKE:
But NA stands for North America no..? I'm from Israel.. Or NA stands for something else? lol

Edit: And yes, I just checked on google, there's a different company called Cellcom in NA..
[ASUS ROG Phone II Guides, News, & Discussion] astracd:
Usually big NA companies own telecoms in other countries overseas.

You can still try it out and see if it will work. But make sure you have your file saved to switch it back if it doesn't work.
[ASUS ROG Phone II Guides, News, & Discussion] MeTaLishSnAKE:
Do I even have to do Step 4 inorder to enable VoLTE? And how do I save my current conf.. ?

@HomerSp how can the ROG II use the 9T MBN files while the phones use two different SoC?
[ASUS ROG Phone II Guides, News, & Discussion] :
Does Boost offer officially VoLTE to premium brands like Samsung and Apple? Because I'm using a low budget MVNO that was accuried by Telia last year. The MVNO doeant offer VoLTE while the owner Telia does. Telia doesn't allow them to have VoLTE because of keeping it a premium feature. Does the hacking tool trick Telstra that the Boost SIM is a Telstra SIM?
[ASUS ROG Phone II Guides, News, & Discussion] Dredead:
Is there anyway to get this working without root?

I've seen the code get thrown around:

*#*#3642623344#*#*

It does make the options appear for VoLTE and VoWiFi, though I get no icons in the notification bar and no hints that it's actually doing anything other than making the radio buttons show in Settings. The reddit thread mentions people having success with only this and nothing else, root included. I'd be happy to paste the code in every start up.

I'm using the Aussie variant sold at JB Hi Fi and I'm with telstra. I gave Telstra a buzz yesterday to activate VoLTE on both my sims in use in this phone, I also just got fresh new sim replacements from them today.

I've copied the APN settings from my old HTC U11 which has VoLTE working. What is this method actually doing or adding to the device that is allowing it to work? Shouldn't it just be a matter of enabling the provisions and the APNs routing the rest?

Any help would be appreciated. I use this phone for work and call quality/drop-outs has been terrible. I'm really hoping this can just bypass those issues, without root.

Cheers
[ASUS ROG Phone II Guides, News, & Discussion] Captain_Throwback:
For the record, that dialer code is:

*#*#ENHANCED4G#*#*

(might make it easier to remember that way ;))

It literally just enables the Enhanced 4G settings, which includes the WiFi Calling option.

However the method in this thread is actually copying the specific Mobile Network settings (MBN) items to the device so that the device radio/modem knows how to enable VoLTE and/or VoWiFi for your specific carrier. Without root you won't be able to do that.
[ASUS ROG Phone II Guides, News, & Discussion] Dredead:
Cheers for that!

Am I able to apply this mod, then unroot and return everything back to stock for the purpose of OTA updates, while still maintaining VoLTE? Would said updates break VoLTE again, having to do it again?
[ASUS ROG Phone II Guides, News, & Discussion] Captain_Throwback:
Once you unlock the device, your device will no longer receive OTA updates. And no, if you return everything to stock, you lose the benefits of this mod.
[ASUS ROG Phone II Guides, News, & Discussion] Dredead:
Ok. Sorry for all the questions, I've only ever rooted HTC devices since the Desire HD, and and the last one I did was the U11, years ago, so I'm a little rusty 😅

I've always gone with custom ROMs, but I plan to stay on the stock ROM for the first time. How would I go about installing official updates without breaking VoLTE? Or is it something I'd have to reapply every time I update?

Also, and perhaps very importantly, do emergency calls work where you're at with this mod? I remember a time when the Diag port could be enabled without root. This sucks a little, what with so many apps like video streaming services now looking for unlocked bootloaders haha.
[ASUS ROG Phone II Guides, News, & Discussion] sin3r6y:
I just wanted to report that I have Verizon nearly fully working using this method with the pixel 4 Verizon mbn. Full LTE, SMS, MMS, and RCS with VoLTE.

Only thing not working is visual voicemail, which may not be related. This was done to a zenfone 6, but should apply to the ROG 2 as well due to the similar hardware.

You will need to have Verizon enable cdma-less features on your account.
[ASUS ROG Phone II Guides, News, & Discussion] wud_e:
Anyone got this working for Android 11? We thought about returning my wife's Asus Zenfone 7 because she keeps missing or getting dropped calls. She loves the phone so much though that she decided to keep it.

When trying to get VoLTE working when it was out of the box rom I was able to do it after a root and using the app. However something weird was going on and the phone would lock when using the dialer. So a new flash was in order and I saw they had Android 11 kn the Asus site. I flashed it, I rooted using magisk and tried the same AsusVolte app. It keeps saying the phone may not be rooted.

Again, 😉 anyone got this working for Android 11?

Perhaps step 1 is already enough to get it working.
[ASUS ROG Phone II Guides, News, & Discussion] The_Insomniac_:
Maybe I'm missing something. I've gone through all the steps and the options are enabled, but I just get an error saying "Mobile network is not available. Connect to a wireless network to make a call." Leads me to believe the buttons showed up but they don't actually do anything. It's the ROG phone II on the Telus Network. Is there something I'm supposed to do with the router also?
[ASUS ROG Phone II Guides, News, & Discussion] Seosam:
Can you finde your phone on Qulacomm tools? Maybe this is the right solution: https://telegra.ph/Trying-out-diffe...-SoCmodem-to-make-VoLTEViLTEVoWIFI-work-07-03

Telus Network is what provider?
[ASUS ROG Phone II Guides, News, & Discussion] The_Insomniac_:
I can find my phone in qualcom tools. I'll give that a look. To clarify, Telus is mobile network, ISP is Starlink. I have been reading that people seem to be inconsistent about whether Starlink works with vowifi. I thought that might be the issue because it attempts to dial out when I connect to a non starlink router but on the same network. I was going to try with a different ISP somewhere else to see if it is actually working.
[ASUS ROG Phone II Guides, News, & Discussion] jfreund:
I've read the thread, and I need help. I have a ROG Phone 3 I'm trying to use on Verizon. Bootloader unlocked, rooted. I have AsusVoLTE installed, granted SuperUser by Magisk. Phone connected with USB. Hit ENABLE VOLTE, toggle Mobile Data. Hit ENABLE DIAG, then START. Looks like this:

QPST finds the phone, says it's on COM30001.

Close QPST, server shuts down. CMD to EfsTools, try to check efsInfo. Critical Error.

Edit .config file to put in COM30001 that QPST said was the port for the phone.

COM30001 does not exist.

OK, try remote. Unplug USB, edit .congfig to set remote=True

Critical error.

Set port=2500, because that's what AsusVoLTE says the port is.

THERE IS NO COM PORT in Device Manager. Here it is with the Asus driver:

Here it is with the ADB Device driver that showed up after I installed the Qualcomm USB drivers.

What am I doing wrong?
[ASUS ROG Phone II Guides, News, & Discussion] Seosam:
Maybe you can try it without the Asusvolte app.

For me it was the only way to activate it.

https://xdaforums.com/t/guide-activate-volte-on-android-11-root.4260705/
[ASUS ROG Phone II Guides, News, & Discussion] jfreund:
I got that to work once. The ADB command must have put the phone in DIAG mode - got a list of "Other Devices" in Device Manager. Ran the install for the Qualcomm drivers and the phone showed up on COM4. Got through the whole process with EFSTools.

I think my mistake was that I did this without the Verizon SIM in the phone. After EFSTools, I shut down, put the SIM in, and powered up. Trying to make a call still popped up "No mobile network".

I tried the whole process again with the SIM in, and never got the "Other Devices", never got the phone to show up in QPST. Even tried a factory reset and no luck.

I'm just going to port the number to TMo. Maybe Verizon will work once they decommission CDMA.

Hello I am currently using the Omni CR. Unfortunately my VoLTE and VoWifi no longer work there. If I take the stick Rome and follow this guide. Then everything goes without problems. But when I start the AsusVoLTE app at Omni Rome. Then it does not ask for root rights. Does anyone know why that is?

Hey man, and for our fellow Telstra mates. I have found an MBN that semi-works for me, from the mi9t. It is the Korean SKT. It holds VoLTE forever, but the calls end immediately. I am not sure what that means.

Anyone know how to reset the modems? Ive tried using the command in TWRP fastboot and nothing happens. Ive also tried in regular fastboot and get an error "FAILED (remote: 'Eraseing non-hlos image is not allowed in lock state')" which I don't understand as my bootloader is unlocked. Any ideas?

Something happened when I was flashing the carrier files and my sim slot one for the Rog 5 doesn't work anymore. No mobile network regardless what I flash to it. So I was hoping to reset the modem to see if it fixes it.
[ASUS ROG Phone II Guides, News, & Discussion] Vojtek12:
So, I reflashed stock firmware, I used the erase command to reset modemst1, but still that sim card slot no longer works. No matter what I flash to it, no mobile network is ever gotten. Anyone know if theres a way I can get modemst2 and replace modemst1? Or any fixes to this? Right now my sim card slot 1 just does nothing. I have to use sim card slot 2 to get mobile network.
[ASUS ROG Phone II Guides, News, & Discussion] Seosam:
Maybe it helps to flash a RAW firmware?! It´s only an idea.

And just using the original mbn doesn't work, too?

Unfortunately not. I have tried that as well. Got the generic one off my phone, loaded it up. Nothing.

EDIT 1: I fixed it somehow. How you ask? I have no ****ing idea. I am sorry. I literally don't know what it is that I did. All I did was erase the modemst1 again, booted up the phone, and kept swapping sims between the slots and it just worked. No idea.

hmm ok. well my carrier doesnt support wlan calling for a 820 phone but with OxygenOS+efstools I got Wlan calling using MTS russia(used to be owned by Telia until 2017). there is a MVNO cellcom in USMobile.

does your carrier support a SD855 phone? Try any major international carrier as Israel cellcom has a roaming deal in Europe or Asia.
