What Is A Sim Chip - Motorola 9505 Series Instruction Manual

What Is a SIM Chip?

Your SIM (Subscriber Identity Module) chip is a
small smart card that contains your phone number,
service details, and memory for storing Phone Book
entries and messages. This means you can use
your SIM chip with any phone for the GSM system
or any Motorola product for the Iridium satellite
system, and all calls go on your account.
Note: Your phone has limited functionality without
the SIM chip.
GSM SIM Chip Capability
If you already have a GSM SIM chip and your
service provider has a roaming agreement with the
Iridium satellite system, you can use it in your
satellite telephone. You need an optional Cellular
Cassette to access your local cellular/PCS service.
Note: If you are using a GSM SIM chip, you may not
have access to certain features that are specific to
the Iridium satellite system, and vice versa.
SIM Chip Protection
Keep your SIM chip in your wallet or purse when
you're not using it. This helps keep your personal
information secure and gives you access to your
service even if your phone is not available. If you
forget your phone, insert your SIM chip into a
friend's phone to access your personal service.
Caution: Avoid bending, scratching, or exposing
your card to static electricity, water, or dirt.
