If you experience problems while using your cell phone, please
refer to the following checklist. If the problem persists, contact your
dealer or nearest service center.
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 cleaning the
contact point of the card. If it is out of order, take it to the nearest
service center.
When the “Handset locked enter password”
message appears:
Enter the handset password. If you cannot remember the password,
contact the nearest service center.
When the “Enter PIN1” message appears:
Type in PIN1. If you cannot remember it, contact the nearest
service center. You can still receive calls even if your cell phone
becomes locked by entering the incorrect PIN1 on three
consecutive attempts.
When the “No service” or “Network failure”
message appears:
Check the SSI (Signal Strength Indicator) state. If you cannot make a
connection in underground areas or in buildings where signal
strength may be low, try moving to another place. If you still cannot
make a connection, contact the nearest service center.
