If you experience any problem while using your mobile phone, please
refer to the following checklist. If the problem still persists, contact your
dealer or nearest carrier.
When the “Insert SIM Card” message appears:
Make sure the SIM card is correctly installed. Check to see if the SIM
card is working properly. If it does not work, try to clean the contact
points of the card with a dry cloth. If it is out of order, take it to your
service provider.
When the “Messages full” message appears:
The received or saved messages are full in your phone memory. You
need to delete the message.

message appears:
The received or saved messages are full in your phone and SIM card
memory. You need to delete the message.
When the “Password” message appears in Phone locked state:
Enter the phone password. The default password is”1234”. If you cannot
remember the password, contact the nearest carrier.
When the “Enter PIN1” message appears:
Input PIN1. If you cannot remember it, contact your service provider.
You can still receive calls even if your mobile phone becomes locked
after entering the incorrect PIN1 on three consecutive attempts.
When the “No Service” or “Network Search” appears:
If you cannot make/receive a call when you are indoors or undergrounds
where the signal strength is poor, move toward a window or go out to an
open area. If you still cannot make a connection, contact your service
provider.
Troubleshooting checklist
When audio quality is poor:
End a call and try again.
When the other party cannot hear you speaking:
Your phone may be set to MUTE. Disable the MUTE function. Or your
hand may be covering the microphone located below the
*
key.
When battery lifetime is shorter than usual:
This may happen when you are in an area with low signal strength. Turn
off your phone when it is not in use. Change the battery when battery
energy is exhausted.
When your mobile phone does not turn on:
Make sure your battery is charged. Check to see if your phone works
while recharging the battery.
When you are unable to send a message:
Either you are not registered to receive an SMS service, or you may be
in an area where your network service provider cannot provide such a
service.
