Dual SIM troubleshooting
Troubleshooting SIM problems on a dual SIM product is very similar to the procedures outlined in the above
section. The presence of the dual SIM IC is detected by the self-test routine, and as such it can be assumed
that presence and interface towards the BB IC is verified if the self-test passes. The troubleshooting guides
will as a consequence focus on dual SIM IC <-> SIM card related problems. It also assumed that troubleshooting
on SIM1 is done using only one SIM card, which is inserted either in slot 1, and troubleshooting on SIM2 is
done using 2 SIM cards, so both slots needs to be occupied.
