Circuit Protection
The module does not have any protection against ESD events or other excursions that exceed
the specified operating parameters (other than very low level ESD protection within the
module’s integrated circuits).
Generally, you should add ESD protection (typically TVS/Transzorb devices) to all signals that
leave the host board. This includes VBAT/VCC.
You can also add series resistors (typically 47 ) in series with data lines to limit the peak
current during a voltage excursion.
Note: Do not add series resistance to the SIM electrical lines.
