@jibel, thanks for the logs. The sequence of registration events that I see is:
D/AT ( 2080): AT< +CREG: 1,"0C94","07EEF3DF",2,0,0 D/AT ( 2080): AT< +CREG: 3,"0D16","0540FD26",2,0,0 D/AT ( 2080): AT< +CREG: 1,"0D16","0540FD27",2,0,0 Apparently the phone tries to register to cell 0540FD26 and it gets registration denied (state=3). It recovers then registration (state=1) after moving to cell 0540FD27. What is weird is that the LAC is the same for both cells (0D16). This implies that both cells belong to the same network, and therefore if the device can register to one of them it should be able to do the same with the other one. As that does not happen, this points to a modem FW error or maybe that some tuning on modem parameters is needed on our side. -- 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.
