Replac ing the SIM Card

modem that is supported by a replaceable SIM card that reside s in

replacement only upon failure, which is rare, or when a change in

replacing the SIM card!
Replace the SIM card (ADS p/n 507181 or customer-supplied) in
the modem in the following way:
1. Deactivate the monitor through Qstart.
2. Remo ve the monitor from the manhole, and place it in a dry,
clean location (i.e., an adequate distance away from the
manhole).
