One
of
the
key
features
of
GSM
is
the
Subscriber
Identity
Module
(SIM),
commonly
known
as
a
SIM
card.
The
SIM
is
a
detachable
smart
card
containing
the
user's
subscription
information.
This
allows
the
user
to
retain
his
or
her
information
after
switching
handsets.
The
SIM
has
a
security
feature
which,
when
enabled,
will
require
the
user
to
enter
a
valid
PIN
before
the
modem
will
connect
to
the
cellular
network.
From
the
Home
page,
select
SIM
Settings
from
the
left
navigation
panel
to
confirm
the
modem
recognized
the
SIM
card.
SIM
STATUS
should
read
ACCEPTED.
PIN
STATUS
may
show
the
PIN
to
be
DISABLED
or
ACCEPTED.
Refer
to
Section
3
for
information
on
changing
the
