2.2.1. SIM Card Slot

The mainboard is equipped with SIM card slot that can support 3G SIM card. Using the SIM card slot on
the VAB-630 mainboard requires a 3G module installed in the miniPCIe slot to enable the 3G function,
otherwise the SIM card slot will be disabled. The SIM card slot is designed only for 3G module without
built-in SIM card slot on it. The SIM card slot is labeled as "SIM1". The pinouts of the slot are shown
