A subscriber identification module (SIM) is an integrated circuit which is used to store the IMSI number. The SIM cards consist of memory capacities such as 32KB, 64KB, 128KB and 256KB. SIM cards are primarily used in GSM phones, CDMA phones, LTE handsets, and satellite phones.

There is an interesting move toward wearable devices as companions to smartphones and other mobile devices, such as smartwatches, health bands, glasses and smart clothes, which present a growth area for smart-card suppliers and mobile network operators. The rising number of these devices in the market is an opportunity for operators and card suppliers to increase SIM penetration for both pluggable and embedded form factors.
