Q: It says
Insert SIM card
in the display.
A: Remove the SIM card and clean it.
Insert SIM card
means that the phone has no contact with the
SIM card in the phone.
• Remove the battery and the SIM card, and clean the
connectors on the SIM card and the phone with an eraser.
• Check if the card is damaged or worn; if so the SIM card
connector may not align with the phone connector.
• Contact your network operator to obtain a new SIM card.
Q: The phone turns itself off.
A: Use the automatic key lock.
If your phone turns itself off when being transported, something
in your pocket or bag has probably activated the on/off key.
Turn on the automatic key lock function.
Q: How do I set up SMS/Text messages?
A: Check the service centre number in the
phone.
If the number to your service centre is not saved on your SIM
card, you must specify the number yourself, otherwise you
cannot reply to received messages or send your own.
Your service centre number is usually provided with your
SIM card. If you cannot find your service centre number,
please contact your service provider.
