The main objective in this study is to prediction of 4G user acceptance in India. Mobile technologies bring more benefits to users when more people use it in the network. This research will show the adoption intentions of 3G mobile technologies. With the completion of this objective of acceptance the next step to estimate the acceptance of 4G technology with the help of Grey Prediction Algorithm. The Grey Prediction Algorithm is the very powerful algorithm that will give better result for short term prediction. This study will support the migration to a more mobile computing environment by identifying the structural and contextual factors that facilitate the adoption of internet technology.
