@jibel, no, that is not happening, you are registered all the time. Some of the lines you see there are not events, but answers to AT+CREG commands.
Event: < +CREG: 1,"0C94","07EE0015",2,0,0 Command and response: > AT+CREG < +CREG: 3,1,"0C94","07EE0015",2,0,0 As you see, it is pretty confusing, as the registration status is in one case the first integer, and in the other case the second one. You can ignore the responses to AT+CREG (remove the lines with the extra integer) and just take the events to follow state. In your case: D/AT ( 2124): AT< +CREG: 2 D/AT ( 2124): AT< +CREG: 2,"FFFF","0FFFFFFF",0,0,0 D/AT ( 2124): AT< +CREG: 3 D/AT ( 2124): AT< +CREG: 1 D/AT ( 2124): AT< +CREG: 1,"0D16","0540FD27",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0D16","05400015",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0D16","0540FD27",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0D16","0540FD27",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0D16","05400015",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0D16","0540FD27",2,0,0 D/AT ( 2124): AT< +CREG: 1,"0C94","07EE0015",2,0,0 so you start searching (2), for a moment you get access denied (3, maybe while authenticating?), then you are registered (1) without further changes. Btw, you can add "-v threadtime" the the logcat command to get timing information. -- 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.
