Mobile Computing is a persuasive computing paradigm which has been incorporated in our daily lives. Mobility in communication has become a necessity and a way of life for both B2B and M2M applications due to the hype of online advertising in social networks and mobile VoIP apps. Although smartphones are limited to processing, memory and power capacity, their advent has made it possible to touch the world with one click, anywhere and anytime. The Global System for Mobile Communications (GSM) model brought about unimaginable revolution to the telecommunication industry and built a profound architecture for most Next Generation Networks (NGN) technology. However, the SIM card technology requirements on various mobile devices and networks is distinct from GSM to CDMA to UTMS but why not provide a universally accessible and standardized virtual SIM as a service offered on demand on the cloud? Additionally, the process of SIM activation varies from one region to another; this is incapacitating at times for diverse Communication Service Provider (CSP) subscribers. This research will seek to design and analyze the architecture for SIM card virtualization being adopted into the Communication as a Service (CaaS) in a Cloud platform and provide Telephony as a Service (TaaS). The virtualization platform will seek to provide multiple virtual SIMs on demand and accessible on any mobile device or browser. Analysis of the GSM SIM card architecture and proposed technology will be drawn while recommendations are envisioned. The key technologies to be used include Web services, Android and Twilio APIs.
