Solution
Somebody tried to use your
phone but didn't know the PIN
code or Unblocking code.
Contact your service provider.
The network connection is lost.
Either you are in a radio sha-
dow (in a tunnel or between tall
buildings) or you are outside of
the network coverage area. Try
from another place.
The display responds more
slowly at very low temperatures.
This is normal and does not
affect the operation of the
phone. Take the phone to a
warmer place and try again.
• Either press and hold
• Or switch off the phone,
check that the SIM card and
battery are installed correctly,
and switch on again.
