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

If you do not need hot-plug detection, keep USIM1_DET and USIM2_DET pins open. The following is a
reference circuit for (U)SIM interface with a 6-pin (U)SIM card connector when hot-plug detection is not
needed.
