Bug Description

When I dual boot from Android 4.4.4 to Ubuntu Touch latest RTM build #41, and with the Utopic builds, most of the times the SIM card is not detected.

To enable SIM card, I have to Toggle the Aeroplane mode to get the SIM card working. There are certain times when this fails and I have to go to /usr/share/urfkill and set flight-mode to 0, then 1 and then back to 0 to get the SIM card working.

I am using Nexus 5 with Multirom Manager for dual booting

This happens to me as well (Nexus4, dual boot from dev channel).

To work around this, I have to execute the following commands:

/usr/share/urfkill/scripts/flight-mode 1 # turn on flight mode
/usr/share/urfkill/scripts/flight-mode 0 # turn off flight mode

After this, the phone may no longer say "No SIM detected", but the mobile carrier may be still listed as "Unknown". To fix this, I further exec the next command:

/usr/share/ofono/scripts/enter-pin pin xxxx

Where xxxx is my SIM's pin and now I can connect to my carrier.

I can confirm that the workaround from @psequeirag works. (Nexus 4 here)
