Hi, when a phone displays an insert sim message, it means that either the Sim card or the Sim tray where the sim card is inserted in the phone.
First, You can use the sim card on another phone to be sure that the sim card is still working properly. If the sim works with another phone, that means the sim tray where the sim card is being insert into the phone is bad and will need to be replaced.
You have most likely already checked this, but just in case.....make sure the sim card is full inserted, and inserted in the correct position. (There should be a diagram showing which way to insert the card.
