@Pat, thanks for the logs. I see something similar as in jibel's: registration is suddenly dropped and then re-established after a few seconds. Sequence is (1: registered, 0: non-registered, 2: searching):

There is a small chance that we need to set some configuration to avoid this though. -- You received this bug notification because you are a member of Ubuntu Phonedations bugs, which is subscribed to ofono in Ubuntu. https://bugs.launchpad.net/bugs/1607823 Title: Cellular connection drops out Status in Canonical System Image: Incomplete Status in ofono package in Ubuntu: Confirmed Bug description: MX4 running 379 from 7/15 I recently noticed the phone was Searching for a signal for some time, even though I know it was connected just prior.
