Hi, I have also strange issue w. Quectel EP06-E LTE modem on my freshly flashed Turris Omnia (TOS7 latest medkit from 02-Apr-2024 02:54). According to the hard inspection of my Omnia seems that modem have some issues w. registration to the home mobile provider (which is O2 CZ operator id: 23002) which leads to missing bearer and network interface wwan0 remains down. Registration to the operator jumping randomly since restart between all available mobile networks (in roaming - if not home):
root@turris:~# mmcli -m 0 --3gpp-scan
---------------------
3GPP scan | networks: 23003 - Vodafone (lte, available)
| 23001 - TMO CZ (lte, available)
| 23002 - O2.CZ (lte, current)
this seems on the first view OK, but 3GPP registration remains always in idle - no bearer, no APN, network interface is down even if I tried to force registration manually:
root@turris:~# mmcli -m 0 --3gpp-register-home
error: couldn't register the modem: 'Timeout was reached'
Here is full modem state according to ModemManager:
root@turris:~# mmcli -L
/org/freedesktop/ModemManager1/Modem/0 [Quectel] EP06-E
root@turris:~# mmcli -m 0

Suspicious is communication w. SIM slot in my Omnia, I see strange things in the ModemManger log:

Without NetworkManager is it the same - here you can see the roaming registration to the T-mobile network:

SIM is present in the slot, PIN request has been disabled and mobile data works OK in my mobile phone. Iām using the default configuration of the modem device interface gsm w. modemmanger (MM) but the same results I got if I stop MM and tried to force registartion by uqmi. There are very old firmware in my modem card (firmware revision: EP06ELAR03A08M4G) do you have the latest one? Omnia fw. has been also updated:
root@turris:~# /usr/bin/omnia-mcutool --firmware-version

There is no other hardware in my Omnia (even WiFI) only on USB is modem device ID 2c7c:0306 Quectel EP06-E
Do you have any idea? Thanks.
