Solution
The SIM card may be incorrectly
inserted. Check the SIM card to
or
make sure that it is inserted
properly (see page 19).
Note: Be sure to turn your phone
off and then back on after you
re-insert the 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 157.
Enter the factory-preset unlock
code (1234), or the last four digits
.
of your phone number (see
page 46). If this fails, call your
service provider (the company
that sends you your monthly
wireless service bill).
The application you want is
locked. If you own the phone but
do not know the unlock code, see
page 49.
