tunnel or surrounded by buildings).
Move and try again.

which you have not taken out a
subscription with your service provider.

• If you have just turned on your phone,
wait for about 2 minutes, until your
phone finds the network and receives a
signal.
• If you are in a tunnel or in an elevator,
the phone may not be able to receive
the network signal properly. Move to an
open place.
• This may appear when you move
between different service areas. It is
normal.

clear
In direct sunlight, you may not be able to
see the display clearly. Moving to a place
with different light should solve this
problem.
