Figure 16: Timing of Resetting Module
1. Use RESET_N only when turning off the module by AT+QPOWD command and PWRKEY pin failed.
2. Ensure that there is no large capacitance on PWRKEY and RESET_N pins.
3.9. (U)SIM Interfaces
EG95 provides two (U)SIM interfaces, and only one (U)SIM card can work at a time. The (U)SIM 1 and
(U)SIM 2 cards can be switched by AT+QDSIM command. For more details, please refer to document
[2].
The (U)SIM interfaces circuitry meet ETSI and IMT-2000 requirements. Both 1.8V and 3.0V (U)SIM cards
are supported.
