Working VoLTE reports, share your experience

I don't know how it works in a mobile network, but in an enterprise network, when you use voIP, a non-compressible part of the bandwidth is reserved for voice (per 64k). Perhaps your 4G coverage isn't good enough to allow voice and data to coexist, and by giving priority to voice, it switches to 3G, which doesn't work at the same time as 4G, which it keeps active to continue voLTE.

@Vlad-Nirky
Thanks. Next time I will test it with sapot.

@Charly
Yes or open a terminal and
ping www.google.com
or
ping 195.238.2.21

@Vlad-Nirky

I tested it again today. First I ping a web page, then I have called my mobilbox. When the mobile connection was set up, pinging was no longer possible.

Vlad Nirky

@Charly
Damn, that's too bad

I guess, it's it's working for xiaomi ( i have made the same test and the ping continue) that could be fixed.
Perhaps could you fill a bug report.

@Vlad-Nirky

Thank you for your support

@TotalSonic I see the Note 9 Pro doesn't support T-Mo's band 71. How's the voice-call support in suburban basements and parking garages and rural areas? E.g., do you ever miss calls when driving on Interstates between major cities?

Vlad Nirky

@RobTheBold
I can't answer because of my european location and this is a north america specific band.
Perhaps could you ask this question on Telegram miatoll channel?

TotalSonic

@RobTheBold - I have no plans to drive on the interstate between cities any time soon, plus I don't answer calls while driving anyway - and there are close to no basements here in central TX, plus this is a test device with a cracked screen, not a daily driver for me. So I am afraid I can't answer your questions at all.

Hi @CiberSheep

Same issue for me.
Also MMS don't work or I have trouble with in (Noble)
But some other people reported SMS and MMS working OK

after some months of using, i know that after start using volte, 4G internet sometimes stop working, maybe after call/sms only thing that helps is to disable/enable data in indicators (no reboot required)
Eric from poco reported that adding new APN may help

For those interested in activating VoLTE on the Poco X3, here are the steps I followed:

After enabling VoLTE, I noticed errors in the logs related to context 1 of ofono. To address this, I replaced this context with a new APN "Internet & MMS" using the commands available in /usr/share/ofono/scripts/.
I also removed an unused connection using ncli connection.

While I can't guarantee that these modifications are the solution, I haven't encountered any issues since.

It's important to note that after exiting airplane mode, the poco often struggles to reconnect to VoLTE without a reboot.

Is this thread only for working reports? cos it doesn't work for me, on either of my phones

libremax

@Caedem Yes, only what works, this thread will be useful if it makes it easier to choose a suitable device for those who absolutely need VoLTE.

@TotalSonic

I'm interested in trying this in the USA. I want to be sure of the model of the Note 9 Pro before I buy one. Is it the Global coverage model? I assume unlocked. (I've installed UT on a few phones and so I am experienced with the struggle to get a really unlocked used phone.) The 9S model is different and not working here, right?

Thank you.
