2.3.6 SIM Card
The GR64 supports an external SIM card through its system connector. A variant of
the GR64 also supports an on-card SIM. For dual SIM support, automated SIM-
switching is available. Both 3V and 1.8V SIM technology is supported. Older, 5V SIM
technology is not supported.
A mechanical variant of the GS64 also supports an on-card SIM. For dual SIM
support, automated SIM-switching is available. Only one SIM is active at any one
time, it is not possible to concurrently register on more than one network.

The power consumption figures shown represent typical average current for
maximum transmitted power, single uplink (transmit) slot, and single downlink
(receive) slot. The module will consume more average power in different multi-slot
configurations, the worst case being that of two uplink and three downlink slots.
