• Circuit switched (dial-up) data connections and type of wireless network

called Code Division Multiple Access (CDMA). CDMA Third Generation (3G)

technology provides a variety of connectivity features, depending on your

service provider and account.

Once a connection is established, you can open your browser and connect to web

sites and access other Internet services such as e-mail.

Accounts and coverage

You must set up an account with a service provider for each MP modem you

install. After installing the MP modem software, you must configure it to use an

account.

If you are using a GSM provider, the service provider supplies a Subscriber

Identity Module (SIM) card—sometimes called a smart card or smart chip—for

each account. The SIM card provides the MP modem’s identity on the network. It

contains account information and must be inserted in the MP modem for the MP

modem to operate.

The ability of the MP modem to obtain service and the type of service obtained in

any area is determined by several factors:

Network proximity and orHSPA availability

To obtain service, you must be within the coverage area of a network operating in

one of the radio frequency bands supported by the MP modem. The type of

connection depends on the service available in that area. For example, there are

areas with /UMTS service in which /HSPA has not yet been implemented.

Roaming If you are within the coverage of a network operated by a different

service provider, your ability to obtain service depends on whether a roaming

agreement exists between your service provider and the one operating your

current local network. There may be additional fees for roaming service. Contact

your reseller or service provider for information.

Account provisions Your account may restrict usage of certain networks or may

limit your connection time or data transmission.
