4.1.2. Hot-plug of (U)SIM
The module supports (U)SIM card hot-plug via the USIM_DET pin. (U)SIM card is detected by
USIM_DET interrupt. (U)SIM card hot-plug is disabled by default.
This is command enables (U)SIM card hot-plug function. The level of (U)SIM card detection pin should
also be set when the (U)SIM card is inserted.
Parameter

<insert_level>
is inconsistent with hardware
design.
2. Hot-plug function takes effect after the module is restarted.
3. USIM_DET is internally pulled up to 1.8 V by software configuration when (U)SIM hot-plug is enabled
by
AT+QSIMDET
.
