Troubleshooting
You need PIN code and PUK code to unlock the phone.
Contact you service provider.
You lose connection with your network. You location may be
a blind area (like in a tunnel or between high-rises) or not
covered by the network. Change you location and try again.
Or contact the service center for advice.
It is extremely cold. Move to a warmer place and try again.
* Press the Clear key.
* Turn the phone off and then check if the SIM card and the
battery are properly installed. Turn on the phone and try
again.
The battery level is extremely low or the ambient temperature
is out of the acceptable range (0~45 Celsius degree). Move
the battery to a warmer place and wait some minutes before
starting charging.
Detach the charger from the phone and replace with a
genuine one.
A car may contain some metal parts that absorb
electromagnetic wave and thus have an adverse effect on
phone performance. Purchase a car kit to allow hand-free
answer. Consult the local authorities about use of phones
while driving.
Press a number key and the number is displayed. When
and
pressing and holding (one second at least) a number key, you
can activate a hotkey (refer to Setting Up a Hotkey) or a
special symbol (e.g. "+" when pressing and hold the [T9+*]
key)
