U)Sim Interfaces - Quectel EM06 Series Manual

NOTE
Please ensure that there is no large capacitance on the RESET# pin.

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.

Comment
Either 1.8 V or 3.0 V is supported
by the module automatically.
Pulled up internally
When (U)SIM1 card is present, it
is at high level.
When (U)SIM1 card is absent, it is
at low level.
Either 1.8 V or 3.0 V is supported
by the module automatically.
Pulled up internally
When (U)SIM2 card is present, it
is at high level.
When (U)SIM2 card is absent, it is
at low level.
