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.
