NOTES
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 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 1.8 V and 3.0 V (U)SIM cards
