Abstract-Telecommunication is among important drivers of globalization. It is a strategic investment which directly contributes to national economic performance bay way of accelerating information exchanges, improving efficiency and transparency. Introduction of faster and more sophisticated telecommunication services into the market affects customers' telecommunication service usage patterns. While subscriptions to traditional means (fixed-line services) decline slowly, adoption of more sophisticated means (wireless services, mobile-cellular phones) spreads remarkably faster. Concentrating on a small sample of fixed-phone subscribers to Turk Telekom, this research identifies three groups of motivations: perceived convenience, business purposes, and perceived advantage. Older customers find fixed-line services more convenient than younger customers, whereas other demographic characteristics such as gender, education, marital status, and duration of fixed-line ownership do not exhibit meaningful differences.
