Subscriber Identity Module (SIM) mini-size (1996 – )

Subscriber Identity Module (SIM) mini-size (2FF) was introduced around 1996 as a smaller version of the full-size SIM, which was too large for newer, smaller phones.

The mini-SIM card has the same contact arrangement as the full-size SIM card and is normally supplied within a full-size card carrier that it can be popped out of, allowing it to be used in phones that use either size SIM.
