Quick question - just wondered what the behavior was of the BR1 with 2 seperate provider SIMs installed and both ports enabled - does it switch between the two SIMs on loss of connection of one or does this have to be done manually?
If the service is EV-DO only, then generally SIM cards are not used for authentication and the MEID is used instead. Currently, there is no way to fail-over from HSPA to EV-DO automatically and this would require a manual change.
