To save the time and expense of an
unnecessary service call, perform the simple

service professional.
When you switch on your phone, the
following messages may appear:
"Insert SIM card"
• Be sure that the SIM card is correctly
installed.
"Enter password"
• The automatic locking function has been
enabled. You must enter the phone's
password before you can use the phone.

"Enter PIN"
• You are using your phone for the first time.
You must enter the PIN supplied with the
SIM card.
• The PIN check feature is enabled. Every time
the phone is switched on, the PIN has to be
entered. To disable this feature, use the PIN
check menu.
"Enter PUK"
• The PIN has been entered incorrectly three
times in succession, and the SIM card is now
blocked. Enter the PUK supplied by your
service provider.
"No service" or "Network failure" displays
• The network connection has been lost. You
may be in a weak signal area. Move and try
again.
