Hi Aleksander, I followed-up on https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/874 and the problem seems to be resolved in newer version. Specifically, I backported these 2 patches: https://github.com/balena-os/meta-balena/pull/3478/commits/2d53d2cb60a155ece0563fbb39629056e2c
