I have just noticed that the output of monitor-ofono is part of the logs, and I see that network status actually gets into roaming state. But, it is in very short time windows:
2014-09-26 20:11:18,643 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 20:11:19,323 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 20:16:31,743 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 20:16:31,803 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:03:43,743 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:03:43,779 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:10:58,077 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:10:58,104 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:18:20,377 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:18:20,411 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:26:05,503 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:26:05,535 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:34:39,565 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:34:39,598 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 22:53:31,359 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 22:53:31,398 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 23:00:20,671 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 23:00:20,732 {NetworkRegistration} [/ril_0] Status = registered ... 2014-09-26 23:07:00,161 {NetworkRegistration} [/ril_0] Status = roaming 2014-09-26 23:07:00,185 {NetworkRegistration} [/ril_0] Status = registered This does not really affect the reasoning above, imho the main problem here is NetworkManager not attaching after coming back to registered state. However, these "Status" flash changes can be annoying and the user could potentially see a flickering roaming indicator in the GUI. I would like to get more traces for this, Víctor, could it be possible to do this: $ phablet-shell $ sudo su # stop ofono # export OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2 # export OFONO_RIL_HEX_TRACE="" export OFONO_RIL_TRACE="" # ofonod -n -d -P stktest,provision,sap,udev,dun,smart,hfp >& /tmp/ofono_log.txt & # python3 -u /usr/share/ofono/scripts/monitor-ofono &> /tmp/monitor-ofono.txt & walk around so the phone switches networks, and then attach the logs here? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to messaging-app in Ubuntu. https://bugs.launchpad.net/bugs/1371032 Title: Cannot send MMS from "Yoigo" Status in “messaging-app” package in Ubuntu: New Status in “network-manager” package in Ubuntu: Incomplete Status in “nuntium” package in Ubuntu: In Progress Status in “ofono” package in Ubuntu: Invalid Bug description: phablet@ubuntu-phablet:~$ /usr/share/ofono/scripts/list-contexts [ /ril_1 ] [ /ril_0 ] [ /ril_0/context1 ] AccessPointName = internet Name = Yoigo Internet Password = Protocol = ip IPv6.Settings = { } Type = internet Active = 1 Username = Settings = { DomainNameServers=217.168.13.34,46.6.113.2, Address=10.192.132.31 Method=static Netmask=255.255.255.0 Gateway=10.192.132.31 Interface=ccmni0 } [ /ril_0/context2 ] AccessPointName = mms MessageCenter = http://mmss/ Name = Yoigo MMS Password = Protocol = ip MessageProxy = 193.209.134.141:80 IPv6.Settings = { } Type = mms Active = 0 Username = Settings = { } phablet@ubuntu-phablet:~$ /usr/share/ofono/scripts/activate-context /ril_0 2 Error activating /ril_0/context2: org.ofono.Error.NotAttached: GPRS is not attached phablet@ubuntu-phablet:~$ /usr/share/ofono/scripts/activate-context /ril_0 1 Additional info: - I didn't see any error in the messaging app. - Couldn't send nor receive MMS. - 3G connection is activated, but usually after a reboot.
