We have had several instances in the past few months where our WP8548 switches to a US based carrier or goes offline and then can’t seem to establish a connection with a Canadian carrier again. Trying
cm data connect and
cm radio off and then
cm radio on had no effect. The only way to restore a connection was to reboot the unit.
This state persited for several days across several different cells in our area. Thoughts on the cause of this and how to get the system out of this state?
