The display says:
Insert SIM Card
or Check SIM Card
even though I
have inserted my
SIM card in the
phone.
The SIM card may be incorrectly
inserted. Check the SIM card to make
sure that it is inserted properly. See
“Installing the SIM Card” on page 19.
The display says:
SIM Blocked. How
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
“Unblock the SIM Card PIN Code” on
page 167.
The display says:
Enter 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 “Locking and
Unlocking Your Phone” on page 164.) 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 “If You Forget a
Code or Password” on page 163.
