Quectel EG25-G modem + eUICC

Hi, We are building a system with a Quectel EG25-G modem + eUICC with the following stack: Network Manager to v1.20.4, ModemManager to v1.10.0, libqmi to 1.24.4, libmbim to v1.20.4 1ot appear to have verified that the EG25-G supports eUICCs (they tested with their own 1oT eSIM) https://1ot.mobi/

could not grab port cdc-wdm0: Cannot add port 'usbmisc/cdc-wdm0', unhandled port

Hi, I have a system with MM 1.16.4 (NM 1.20.4) and I'm facing some problems with my SIMCOM SIM7600G-H In some systems, I get a successful activation of the cdc-wdm0 device and the wwan0 interface comes up and in some other systems, cdc-wdm0 fails to be grabbed/activated and the wwan0 stays down.

How to retrieve the actual timezone from the network

How to check if the APN supports IPv6

Modem reset issue

Hi, I'm resetting the modem (SIMCOM_SIM7600G-H) with mmcli (mmcli 1.16.10) The modem status was fully connected before running: $ mmcli -m 0 --reset successfully reseted the modem After the reset, the device does not connect anymore, and only power cycling put things back to normal. Modem Mana

How to trace the communication with the modem?

Hi, I am trying to debug the reset sequence of my modem (I've posted today a separate message about this). I was wondering if there is a way to trace the communication between MM and the device, or perhaps between libqmi or the device to output the content and translation of the QMI messages (or

VolTE support

Hi, I'm trying to figure out if there is a way to verify if VolTE is enabled or not on a modem (SIMCOM SIM7600G-H). I've noticed this issue in the bug tracker: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/378 so I understand that MM has no APIs to verify that. Does anyo
