[Guide] Enabling VoLTE/VoWiFi v2

[Zackhery]

Has anyone attempted this with Verizon? I dropped my note 9 and cracked the screen and was eye balling a Rog 2

I dont have mbn files for Digi (malaysia). So i cant proceed to step 4. Can i skip it?

I'm using AT&T, and I followed the guide and it works to get VoLTE on my device. But shortly after starting the phone up the first time with the SIM card, VoLTE gets disabled, assumedly from AT&T doing some provisioning. Should this be happening? I'm using WW-16.0631.1910.64, and I've tried using a few different MBNs, including the ASUS VivoVoWiFi_v5 one from the first guide. Does this sound like a purely MBN issue? I'm surprised to see that many folks had AT&T working on the first guide, because I followed that after this one and had the same experience where I'm shutdown after a bit of being VOLTE.

The ATT MBN from this thread didn't work for me. I used the vivo MBN from the first thread and it now works. I'm on 64 and have the VoLTE icon. When making calls the VoLTE icon stays and doesn't go to H+.

What APN are you using?

What APN are you using to get it to work? Does it seem to make a difference or have you tried other ones?

Thanks!

Any chance this would work on the US version of the ROG 1? Or anything that might differ step wise?

It probably should work, yes. As long as you can get diag mode, the steps should be identical. I know some people ran this to get working volte on the ZenFone 6.

I tried putting in the 'code' in the dialer. Sure enough, it made the settings visible for VoLTE and WiFi calling, but even with them 'on' It didn't do anything, any calls I'd make would still drop right down to Edge. This is on a completely stock ROG I, though.

I'll attempt the process and see how it works. I have my Razer 2 and that has working VoLTE on T mobile, the same sim in the ROG, not so much. The only bands it was pulling off of for both phones was two or four around here I believe, which is NC (USA.)

Your still going to have to do the steps in this thread also.

Followed the steps with no errors but even pushing the Telus mbn (also tried Vivo) doesn't give me volte for Koodo (subsidiary of Telus). I guess I need a real Koodo mbn (maybe from the Pixel 4). I wonder how these are extracted.

After pushing the .mbn file I open pdc advanced tool and I see my phone on the same profile as before. No error on the commands while pushing the .mbn. Should it update in pdc? Ex. If I was on tm_commercial before and I pushed the ATT_Volte, whe I open PDC would it show ATT_Volte as active?

I'm on Verizon as well and just considering getting the Rog 2. Any results to speak of? Else I can be the guinea pig.

I'm on verizon. Went through the steps and only got volte enabled(tried all the verizon files, but only the first one worked). Can make/recieve phone calls and send texts, but i cant recieve them. I dont think its an app setting. I tried 4 different ones and looked through settings and same outcome. The text message (SMS and MMS) goes out fine and gets recieved but my rog 2 never receives the replies sent to it.

Anyone have an idea? Im guessing sms does not work through volte service.....but then how would my messages be sent?

Anyone have this working on Bell/Virgin in Canada ?
Also if i try this and it does not work will the phone still have service as normal ?
Thanks.

What does the below command do? Does it keep the new mbn from being overwritten in an ota update.
.......nv/item_files/mcfg/mcfg_autoselect_by_uim

I'm having an issue where powershell opened in the efstools folder doesn't recognize efstools.exe as a command.

UPDATE: I figured it out. I will be activating the phone to see if it works now without missing calls or texts. THANK YOU!
