Companies
that
operate
networks
and
provide
access
to
these
networks
are
called
service
providers
.
To
use
the
Compass
USB
modem,
you
must
have
an
account
with
a
CDMA
service
provider.
Note: You can use the Lock
Modem feature to prevent others
from using your account, should
your Compass USB modem be
stolen. For information on this
feature, see the
Each
service
provider
has
its
own
pricing
options.
There
may
be
flat
rate
accounts,
which
provide
you
a
maximum
number
of
minutes
of
network
usage
for
a
fixed
monthly
fee.
There
may
be
accounts
for
which
you
are
charged
for
network
usage
by
the
minute
or
by
the
amount
of
data
transmitted.
Your
account
may
include
a
variety
of
other
services
such
as
SMS
messaging
or
location
‐
based
services.
Each
Compass
USB
modem
has
been
provisioned
at
the
factory
for
use
with
a
particular
service
provider.
This
sets
the
Compass
USB
modem
to
use
particular
radio
channels
and
enables
services
specific
for
that
provider.
The
process
of
setting
up
your
account
is
called
activation
.
Activation
involves
action
by
the
service
provider
and
configu
‐
ration
of
the
Compass
USB
modem.
The
procedure
to
configure
(activate)
your
Compass
USB
modem
is
covered
in
The CDMA wireless network
Note: More information about
networks is available on
the CDMA Development Group
web site,
.
This
is
the
worldwide
infrastructure
providing
the
radio
coverage
that
allows
you
to
stay
connected.
Made
up
of
radio
towers
and
a
variety
of
network
switches,
routers,
and
servers,
the
network
is
an
interconnection
of
many
service
providers.
Note: Most service providers
have coverage maps on their
web sites.
There
are
networks
that
operate
in
the
frequency
bands
supported
by
the
Compass
USB
modem
throughout
North
America
and
parts
of
Latin
America,
Asia,
and
New
Zealand.
However,
each
service
provider
operates
a
network
that
covers
a
limited
geographical
area
within
the
overall
CDMA
coverage
area.
Note: The fee for service is
usually higher when you are
roaming (connecting to a
network other than the one
belonging to your service
provider).
Most
service
providers
have
agreements
with
other
service
providers,
so
that
they
can
offer
service
outside
of
the
coverage
area
of
their
own
networks.
For
example,
assuming
you
live
in
Vancouver
(Canada),
and
travel
frequently
to
Seattle
(United
States),
you
can
obtain
an
account
with
a
Vancouver
service
provider
that
has
a
roaming
agreement
with
a
service
provider
in
Seattle.
You
would
then
have
local
service
in
Vancouver,
and
roaming
service
in
Seattle.
