Troubleshooting
Solution
Be sure to press and hold
Power key) until the display appears and
you hear an audible alert (this could
take a couple of seconds). If nothing
happens, check that a charged battery
is installed. (See "Charging the Battery"
on page 22.)
The SIM card may be incorrectly
inserted. Check the SIM card to make
sure that it is inserted properly. See
"Installing the SIM Card and Battery"
on 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
. How 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 158.
Enter the factory-preset unlock code
(1234), or the last four digits of your
phone number. (See "Locking and
Unlocking Your Phone" on page 155.) If
this fails, call your service provider (the
company that sends you your monthly
wireless service bill).
