Unable to connect 4G/LTE Modem. ModemManager shuts off as soon as it tries to connect

  • 772

When I run ModemManager --debug on the terminal, I get this output.

Running mmcli -L gives me:

/org/freedesktop/ModemManager1/Modem/0 [huawei] E3372

And running mmcli -m 0 gives me this output.

When I try to start modemmanager by sudo /usr/sbin/ModemManager, I get:

ModemManager[9099]: <info> ModemManager (version 1.10.0) starting in system bus...
ModemManager[9099]: <warn> Could not acquire the 'org.freedesktop.ModemManager1' service name
ModemManager[9099]: <info> ModemManager is shut down

I've been trying all the solutions on Google but to no avail. Any help is greatly appreciated!
