3.7. (U)SIM Interfaces
The (U)SIM interface circuitry meets ETSI and IMT-2000 requirements. Both 1.8 V and 3.0 V (U)SIM
cards are supported, so does the Dual SIM Single Standby function.
Table 9: Pin Definition of (U)SIM Interfaces
EM06 series modules support (U)SIM card hot-plug via the USIM_DET pin, a level trigger pin normally
Please ensure that there is no large capacitance on the RESET# pin.
