SIM CARDS FUNCTIONS AND POSITIVE IMPACT ON NIGERIAN ECONOMY

Abstract

In this jet age, it is unfathomable to imagine modern life without mobile technologies. One of the most important components of these information communication technologies is the SIM subscriber identification module’, an integrated circuit specially created for storing the international mobile subscriber identity – IMSI. SIM cards are used on various devices like mobile/satellite phones, cameras, computers, etc. Further miniaturization has been carried out on SIM cards over the years; it gathers and stores network specific information to identify a subscriber. Some of the blessings are in Job creation and employment, where many people are self- reliant. Some have also learnt the technical aspect of repairing and fixing mobile phones in their repair shops. Sales of GSM phones and its accessories are big business. Examination bodies, automotive, entertainment, educational institutions, media houses, and government agencies have also employed this technology. Socially, we have benefited in the corporate social responsibility of the service providers and phone companies. Relationships with friends, associates, relatives and loved ones are kept alive through phones calls, investors are showing interest in Nigeria because of the rapid increase and return on investments.
