Make sure the SIM Card is installed
correctly.
The phone might be switched off; to
switch on the phone, press and hold
the red receiver key for about 3
seconds.
If you have not used the phone for a
long time, the battery might be
"deeply-discharged"; to recover a
deeply-discharged battery leave your
charger plugged in, although there
will be no image on the display.
