At the night only it reaches on 1.0 mbps, untill unless no surfing speed no downloading and uploading speed .and the social networking sites are also cant able to run smoothly .and ome more thing after the use of 4gb data from your simcard connection perday or on a particular day the speed will reduce at 128 kbps .so what is the meaning of unlimited 4g data .dont go for it those having poor network area .
