I pressed the 
End/Power 
key, but 
nothing 
happened. 
Be sure to press and hold 
O (the 
End/Power key) until the display 
appears and you hear an audible 
alert (this could take a couple of 
seconds). If nothing happens, 
check that the battery is charged. 
(See “Charging the Phone” on 
page 20.
)
I pressed keys, 
but the display 
has stopped 
responding.
You might need to reset your 
phone. See “Resetting Your 
Phone” on page 20.
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 “Changing Your SIM 
Card” on page 16
.
Note: Be sure to turn your phone 
off and then back on after you 
re-insert the SIM card.
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 115
