The tri-mode phone can be thought of as “two phones in one” because it operates in two

distinct ways to make and receive two types of calls:

• Globalstar satellite calls

• Digital or analog cellular calls

Using Globalstar satellite mode requires that the Security Module card be properly installed

in the front lower left side of phone. It contains the Globalstar authentication key (A-key)

that is used in the authentication process, as well as a unique ID number and the user’s

service plan options. Installation allows the tri-mode phone to receive a call or to make

non-emergency Globalstar calls. The security module card installed in the phone is not

interchangeable; it only works with that phone.

The Service Provider installs and maintains the security module cards from its home

service area. Note that the security module only prevents unauthorized Globalstar calls.

Cellular calls can be made without the security module card.

The Globalstar A-key authentication process occurs when the tri-mode phone is turned on

in the Globalstar mode. A signal with information that includes the A-key and the unique

ID number is sent from the phone to a Gateway. An authentication process is performed

using the corresponding data in the Service Provider’s authentication database. When the

results are matched the phone may be used.
