Reseting mobile connection - Librem 5

Hardware Librem 5

Thank you for the clarification. It appears not to be running as a service on my phone or maybe has a different name?

sudo systemctl --system enable watchmodem
[sudo] password for purism:
Failed to enable unit: Unit file watchmodem.service does not exist.

Correct. I aligned the name with the package name. Here’s how the package looks on my phone:

purism@pureos:~$ dpkg-query -W bm818-watchmodem

Since the modem seems to cut out and not restore after wake from suspend I am seeing if this could be adopted for postmarketOS?
