Each SIM is internationally identified by its integrated circuit card identifier (ICCID).ICCIDs are stored in the SIM cards and are also engraved or printed on the SIM card body during a process called personalisation.Modern SIM cards allow applications to load when the SIM is in use by the subscriber.These applications communicate with the handset or a server using SIM Application Toolkit, which was initially specified by 3GPP in TS 11.14.The first SIM card was developed in 1991 by Munich smart-card maker Giesecke & Devrient, who sold the first 300 SIM cards to the Finnish wireless network operator Radiolinja.Today, SIM cards are ubiquitous, allowing over 7 billion devices to connect to cellular networks around the world.The SIM circuit is part of the function of a universal integrated circuit card (UICC) physical smart card, which is usually made of PVC with embedded contacts and semiconductors."SIM cards" are transferable between different mobile devices.
However, a single issuer always uses the same size for its ICCIDs.
SIM cards are always used on GSM phones; for CDMA phones, they are only needed for newer LTE-capable handsets.
SIM cards can also be used in satellite phones, computers, or cameras.
This does not mean that a phone containing this SIM card can connect to a maximum of only 33 or 80 networks, but it means that the SIM card issuer can specify only up to that number of preferred networks.
If a SIM is outside these preferred networks it uses the first or best available network.
