There are three different ways a SIM card can become faulty:
1. The card is physically damaged. By being cracked, dropped in water etc.
2. The data on the card can be corrupted. This can be caused by shutting down the phone at the wrong time. Some phones will also destroy the card if you enter too many bad passwords.
3. The card itself is fine, but there is a problem with the phone company's record of the SIM card. This can happen when "porting" a phone number from one carrier to another. It could also be "blacklisted" due to unpaid bills.
