No, this doesn't work. It seems like the communication with the modem
gets out of sync, as I see a lot of "No transaction matched in received
message" messages after restarting ModemManager.

I attached a log of

- suspending while being connected via the modem
- resuming from suspended state
- trying to connect
- restarting ModemManager

Hope this helps!
