Is it a new SIM? if not, it probably reached its end of lifetime. Replace it for a new one.

the pins that touch the sim card could be lose or the sim card might be bad, try pulling the pins on the phone up carefully just a little so its a little more thighter to inser the sim card, then try again, also try another sim card if it doesn't help.
