The display
says:
SIM Blocked

do I unblock my
SIM card?
Call your service provider (the
company that sends you your
monthly wireless service bill) to
obtain the PIN unblocking key (PUK)
code. See page 145.
The display

Unlock Code
. How
do I unlock my
phone?
Enter the factory-preset unlock code
(1234), or the last four digits of your
phone number (see page 41). If this
fails, call your service provider (the
company that sends you your
monthly wireless service bill).
My phone asks
for an unlock
code when I try
to open a
feature.
The application you want is locked. If
you own the phone but do not know
the unlock code, see page 44.
My phone does
not ring.
If you see
a
or
W
in the display,
then the ringer is turned off. To
change the ring style, see page 52.
Also, the ringer may be set to
Silent
even though your phone is set to a
ring alert profile.
My phone rings
even though I
selected the
Silent
(or
Vibrate
)
alert profile.
The ringer may be set to play a tone
even though your phone is set to a
silent alert profile. To change the ring
style, see page 52.
I tried to place a
call and heard an
alternating high/
low tone.
Your call did not reach the wireless
system. You may have dialed the
number too soon after turning the
phone on. Wait until the display
shows the name of your service
provider before making a call.
