I bought the Tata photon max WI-Fi Data card 2 years ago in the first 2 mount he performs well but after a two mount its speed become very slow. Its Internet speed become very slow . Its connection drop in 5 or 6 time in one day.
But its feature is really too good. connection Reliability is very slow . its service and sports center work in few times in day. I recommend if in this data card few best feature are added this Data card become very famous
