EG95 supports (U)SIM card hot-plug via USIM_PRESENCE (USIM1_PRESENCE/USIM2_PRESENCE)
pin. The function supports low level and high level detections. By default, it is disabled, and can be
configured via AT+QSIMDET command. Please refer to document [2] for more details about the
command.
The following figure shows a reference design for (U)SIM interface with an 8-pin (U)SIM card connector.
