1. Use RESET_N only when failed to turn off the module by AT+QPOWD command and PWRKEY pin.
2. Ensure that there is no large capacitance on PWRKEY and RESET_N pins.
3.9. (U)SIM Interface
The (U)SIM interface circuitry meets ETSI and IMT-2000 requirements. Both 1.8V and 3.0V (U)SIM cards
are supported.
