I've installed 29/01/2014 Ubuntu Touch on my Nexus 4 (with .84 radio from Android 4.3). I can make/receive calls and connect to wifi but when I turn wifi off I see a 3G icon flash up two or three times in the top bar but then just the "no connection" icon. There is definitely no data connection. I understood that this should be working without any user intervention. My imei shows up in "about", mobile data is set to "on" and my carrier is correctly identified as "O2 UK".
Can anyone please point me in the right direction?
BTW I already tried creating a mobile data connection in desktop and then copying to "/etc/NetworkManager/system-connections" and bringing up with "nmcli con up id" etc but I got the error that the connection was not supported by oFono.
