Description & Solution
This may happen if you turn on the
phone after a long period of disuse, or
after removing the battery without
turning off the phone. This is not related
to the phone's life or performance. The
display should correct itself shortly.
The automatic locking feature has been
enabled. You must press the Unlock soft
key and enter the lock code before you
can use the phone. To disable this
feature, go to Settings → General →
Security → Phone and SIM card and
set Phone autolock peri... to None.
• You are using your phone for the first
time. You must enter the Personal
Identification Number (PIN) supplied
with the USIM/SIM card.
• The PIN code request feature has been
enabled. Each time the phone is
switched on, the PIN has to be entered.
To disable this feature, go to Settings
→ General → Security → Phone and
SIM card and set PIN code request
to Off.
The PIN code was entered incorrectly
three times in succession and the phone
is now blocked. Enter the PUK supplied
by your service provider.
