3.8 (U)SIM Interface
SIM8300G-M2 supports (U)SIM1 cards and e-(U)SIM(internal of the module) card , the size is
2mm*2mm*1mm of the e-(U)SIM. Both (U)SIM1 and e-(U)SIM are dual-voltage 1.8V or 3.0V.
Customers choose the e-(U)SIM products according to the above size, SIMCom will provide the
e-(U)SIM assemble into the module.

The module supports (U)SIM card hot-swap by the (U)SIM_DET pin, which is a level trigger pin. The
(U)SIM_DET pin pulled up internally.
The following figure shows (U)SIM card reference circuit.
