20 Using Your Phone
What Is a SIM Card?
Your SIM card (Subscriber Identity Module)
contains your phone’s 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.
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
Keep your SIM card in your wallet or purse when
you are not using it. This helps keep your personal
information secure and gives you access to your
service even if your phone is not available.
Caution: Avoid bending, scratching, or exposing
your card to static electricity, water, or dirt.
