Public Mobile (Canada): failure to configure VoLTE - digdis - 07-11-2025

I'm having an issue where my PinePhone can use the 4G network for data and SMS/MMS (in/out), but I'm unable to hold a call on the 4G network. Currently the call immediately degrades to the 3G network, and if I force exclusive usage of the 4G network, my calls fail to connect entirely.

Here's my current setup:
PinePhone v1.2b Beta Edition
postmarketOS (systemd; edge release) -- Phosh UI
calls 48.2 (GNOME)
default firmware for the Quectel EG25-G modem (I've not yet tried https://github.com/the-modem-distro/pinephone_modem_sdk).

network: Public Mobile (Canadian subsidiary of TELUS)

I've been following https://pine64.org/documentation/PinePhone/Modem/ to attempt to set up VoLTE.

Using the default profile ROW_Generic_3GPP and subsequently trying the profile Telus-Commercial_DO, I've sent AT commands in this way:
Code:
echo 'AT+<command here>' | sudo atinout - /dev/ttyUSB2 -

When I enable IMS, I get the okay:
Code:
AT+QCFG="ims",1
Code:
OK

However, after restarting the modem with AT+CFUN=1,1 I am unable to place a call, just as before. Indeed, when I query the IMS status, I'm told that VoLTE is disabled:
Code:
AT+QCFG="ims"
Code:
+QCFG: "ims",1,0 OK

I've also tried to enable VoLTE following https://quectel.com/content/uploads/2024/02/Quectel_EC2xEG2xEG9xEM05_Series_QCFG_AT_Commands_Manual_V1.0.pdf
Code:
AT+QCFG="volte_disable",0
Code:
OK

But the issue still persists following a modem restart.

Does anyone have experience in getting VoLTE to function with this carrier or in a similar situation? I'm unsure whether I'll have to change carriers altogether.

I don’t have TELUS, but Quectel firmware documentation says “Fixed the problem that Telus VoLTE could not make VoLTE Call.” for version “R07A08_30.003.30.003”, in case your firmware is older than that.

Right, I have version 30.004.30.004, so in theory that firmware issue shouldn't be present.

Hi, one of the following commands should show how many profiles you have: 

Code:
AT+QMBNCFG="list"

Or
Code:
mmcli -m any --command='AT+QMBNCFG="list"'


You can find out what version of the firmware you are currently using after entering the command:

Code:
mmcli -m any --firmware-status

You can provide this information to clarify your situation.

According to the statement you have 24 profiles, it looks fine.  Still, you should probably try the newer firmware.
I can recommend version 30.006. Or Custom firmware you wrote about in the first post, version 0.8.0.

RE: Public Mobile (Canada): failure to configure VoLTE - digdis - 07-14-2025

I've followed the instructions in https://github.com/the-modem-distro/pinephone_modem_sdk/blob/scarthgap/docs/FLASHING.md (release 0.8.0) and upgraded to ADSP Version 30.006.30.006, but the issue persists: calls will not connect through the 4G network.
