In the past, the telephone and postal services were the means of communication. Nowadays, many more means of communication are in use. Among them are telephone, electronic mails, computer, internet etc.

TELEPHONE SERVICES

Business-life today would be inconceivable and Herculean task without the telephone services. About a decade ago in Nigeria, telephone services were monopolized by Nigerian Telecommunication Limited (NITEL)

and its subsidiary (MTEL) both providing fixed line services and mobile cellular functions. Their services were only for the well-to-do business tycoons, chief executive officers, powerful political appointees, top brass in military and paramilitary; foreign envoys, articulate bankers and industrial monguls. Members of academic community and dedicated civil servants were unable to own one due to their poor status and irregular take home pockets. Multi-links was the only recognized private service provider then, and the services provided were very limited and reservations of the riches as listed above. Then, the charges were made by combination of a fixed monthly, rental and payments which depended on numbers and lengths of the calls, distances over which they are made and the time of the day at which they were made.

By 2001, the monopoly status enjoyed by NITEL was broken by Olusegun Obasanjo administration and thereby licensed private firms to invest in telecommunication industry. That singular act gave birth to tie first three (3) companies to be licensed to carry out Global System of Mobile telecommunication (GSM). The three successful companies then were: MTN, MTEL and ECONET (later CELTEL, now ZAIN). The code for them are: MTN (0803) MTEL (0804) and then ECONET (0802)

As at December 2008 in Nigeria, we have over ten (10) private telecommunication providers both on Global System Mobile telecommunication and fixed land lines. Among them are MTN, ZAIN, GLOBALCOM, ZOOM (formerly Reltel), Etisalat, Visafone,’ Multilink, Oduatel e.t.c
