Note: ESD protection is highly recommended for the USIM connector
at the point where the contacts are exposed, and for any other signals
from the host interface that would be subjected to ESD by the user of
the product.
Module power states
Note: The module unit defaults
to the Normal state when
VCC3.3 is first applied in the
absence of W_Disable# control.

Disconnected state
Note: The difference between
the Disconnected and Off states
is that, in the Off state, the
module is still connected to the
power source and draws minimal
current.

Device-generated RF
Note: The module can cause
interference with other devices
such as hearing aids and on-
board speakers.
Wireless devices such as the
Mini Card transmit in bursts
(pulse transients) for set
durations (RF burst frequencies).
Hearing aids and speakers
convert these burst frequencies
into audible frequencies,
resulting in audible noise.
