Sim cards are small plastic chip cards which are used for storing AT&T SIM data such as contacts and call logs in cell phones and work in GSM network frequencies for maintaining service provider data and phone number. Usually, the SIM cards are provided on their network by the network service provider and the lost card information must be programmed to replace the SIM cards.
