This tutorial presents a business case for the use of smart cards or subscriber identity modules (SIMs) in the marketing and network operations of wireless communications operators. The business case focuses on the SIM card’s marketing, financial, and technical benefits to network operators as well as benefits to wireless consumers. Some key external factors likely to accelerate customer acceptance are also discussed.
Overview
Today, the SIM card’s basic functionality in wireless communications is subscriber authentication and roaming. Although such features may be achieved via a centralized intelligent network (IN) solution or a smarter handset, there are several key benefits that could not be realized without the use of a SIM card, which is external to a mobile handset. These benefits—enhanced security, improved logistics, and new marketing opportunities—are key factors for effectively differentiating wireless service offerings. This tutorial assumes a basic knowledge of the wireless communications industry and will discuss the security benefits, logistical issues, marketing opportunities, and customer benefits associated with smart cards.
