G30 - Module Hardware Description
December 15, 2009
Both 1.8 V and 3 V SIM types are supported; activation and deactivation with automatic voltage
switch from 1.8 V to 3 V is implemented.

G30 is designed to support two SIM card options with the same SIM signals: External SIM card,
or an on board Embedded SIM (eSIM), depending on the G30 model.

External SIM Card
G30 does not incorporate an on-board SIM card tray for SIM placement. The external SIM must
be located on the user application board, external to the G30. The G30 SIM interface includes all
the necessary signals, which are routed to the interface connector, for a direct and complete
connection to an external SIM.

G30 supports dynamic detection of the SIM card, through a dedicated SIM detection signal. G30
will detect a SIM card insertion or removal upon power up or during operation by the transitions
on the SIM_PD_N signal.
