SC200R series module supports (U)SIM card hot-plug via the USIM_DET pin. (This function is disabled
by default via software. To enable it, contact Quectel Technical Supports to change the software
configuration.) A reference circuit for (U)SIM interface with an 8-pin (U)SIM card connector is shown
below.
