Building public Internet access points (PIAPs) is a significant contribution of governments towards achieving an information society. While many developing countries are investing great amounts to establish PIAPs today, people may not use PIAPs effectively. Yet, the successful implementation of PIAPs is the result of citizens' acceptance to use this opportunity. Hence, based on the Diffusion of Innovation Model, this study aims to detect the determinants of behavioural intention to use PIAPs. Essential data were collected from 3477 users of BELNET PIAPs established by the municipality of Istanbul in Turkey. We found that observability, compatibility and relative advantage all positively impact the intention to use PIAPs. The results reveal academic and practical implications for the future development and implementation of PIAPs.
