Compass Series HSPA USB Modem Installation Guide
Note: If you purchased the
Compass USB modem from a
GSM service provider, you may
already have an account and a
SIM card. Otherwise, your
retailer should be able to give
you the names of companies
that provide these items.
Note: The fee for service is
usually higher when you are
roaming (connected to a network
other than the one belonging to
your service provider).
• Enhanced Data rates for GSM Evolution (EDGE)—
236 kbps
• General Packet Radio Service (GPRS)—56 kbps
GPRS and EDGE are second generation (2G) data services.
UMTS and HSDPA/HSUPA are 3G data services.
When establishing a connection, your Compass USB modem
uses the fastest available service. If, for example, you are using
a Compass USB modem in an area that has GPRS and EDGE
service but not UMTS or HSDPA/HSUPA service, the Compass
USB modem connects using EDGE service.
Once the connection is established, you have access to all
Internet services.
Your account and coverage area
You must have an account with a GSM service provider to use
the Compass USB modem. To use the modem’s 3G capability,
your account must be with a service provider that offers
HSDPA/HSUPA or UMTS service. (The Compass USB modem
is backwards compatible with 2G service.)
When you obtain your account, you are given a Subscriber
Identity Module (SIM) card containing account information.
Before you use the Compass USB modem, you must insert the
SIM card into it.
Your ability to obtain service depends on these factors:
• GSM network coverage—You must be within the
coverage area of a GSM network.
• Service provider—If you are within the coverage area of a
network that is not operated by your own service
provider, you can obtain service only if there is a roaming
agreement between your service provider and the network
operator.
• Account provisions—Your account may restrict your
usage to certain networks or limit the amount of time you
can use the network.
• Frequency band—You cannot connect to networks
operating in bands not supported by your Compass USB
modem, regardless of roaming agreements or account
provisions.
Most service providers have coverage maps on their web sites.
