Comment 2 for bug 1427306

There is an isolation issue between the ubuntu_sanity_tests.tests.test_sim_pin.SimPinTestCase.test_sim_pin_lock_and_unlock and ubuntu_sanity_tests.tests.test_flight_mode.FlightModeTestCase.test_switching_on_flight_mode_must_engage_flight_mode

While the former works whether SIM is initially locked or not, the later make othe tests fail if the SIM is initially locked.

https://bugs.launchpad.net/ubuntu-sanity-tests/+bug/1408727 took care about the SIM test may be some code can be re-used.
