SOURCE: WHY DOES MY PHONE SAYS INSERT SIM

try taking SIM and battery out placing it back in an powering on.

If you try this and it still does not work you may need a new SIM card. Take it to a local dealer they should have a new SIM they will put your number on it and you will be back in business.

If the new SIM doesn't not work you will now know it is your Phone, which means time for a new one.

good luck
