VIA VAB-950 User Manual
3.2 SIM Card Slot
The VIA VAB-950 comes with a SIM card slot that supports 4G SIM cards. SIM card usage on the VIA VAB-950
requires that a 4G module is installed in the miniPCIe slot, enabling the 4G functionality, otherwise the SIM
card slot will be disabled. The SIM card slot is designed for use with 4G modules that do not support built-in
SIM card slots. The pinouts of the SIM card slot are shown below.
