Network connections
The MP modem operates over the following networks, with
connectivity and speed dependent on your service provider
and account:
• High Speed Uplink Packet Access (HSUPA) — up to
2.0 megabits per second (Mbps)
• Universal Mobile Telecommunications System
(UMTS) — up to 384 kilobits per second (kbps)
• Enhanced Data GSM Environment (EDGE)—up to
236 kbps
• General Packet Radio Service (GPRS)—up to 56 kbps
• Circuit switched (dial‐up) data connections
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.
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. (See
“Insert the SIM Card” on page 38.)
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 HSUPA 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 HSUPA 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.
