What Is a SIM Card?
Your SIM (Subscriber Identity Module) card 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 card 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 card.

GSM SIM Card Capability

If you already have a GSM SIM card 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 card, you may
not have access to certain features that are specific
to the Iridium satellite system, and vice versa.

SIM Card Protection

You may want to keep your SIM card in your wallet
or purse when you are not using your satellite
phone. 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 card into a friend’s phone to
access your personal service.
Caution: Do not bend or scratch your SIM card,
and avoid exposing your card to static electricity,
water, or dirt.
