Now you are circumventing the service with unknown consequences (unless you checked how ModemManager.service is configured). It's much cleaner if you interact with the service and not the utility itself.Code:if [ -e /dev/ttyUSB2 ]
echo "modem works"
else
echo "modem does not work, restarting now ..."
sudo killall ModemManager
sudo /usr/bin/ModemManager &
fi
Your phone always crashing in deep sleep is a much bigger problem though that I would investigate. I don't have anything off the top of my head, but I would check what happens in the logs with journalctl or dmesg.

Thank you; in my mind these 2 problems are about equally bad
I followed your advice, maybe you can help? Seems I have a problem with some swap partition?

PS
You are right of course about how I should restart the ModemManager service. I will follow-up on that
