It might be that there is some corrosion on the leads that connect to the SIM card. You can try using a soft pencil eraser on the leads to see if you can clean them up, being careful not to get any debris from it in the phone to avoid any future strange complications.

Try the SIM in another phone. SIM cards go bad.
If it doesnt work in the other phone it will have to be replaced. I
THis can also be caused if you set up a PIN code and it was entered in wrong too many times and you did not use the right PUK code to unlock it. THis will permanently damage a SIM card.
f it does work in another phone then your phone is no longer able to read SIM cards. Check with the manufacturer for warranty info.

SOURCE: Insert SIM Card

My phones displays the message Insert SIM Card even though it has the SIM Card.
