The unlimited data plan of ?800 per month has very low speed.sometimes it goes upto 100kbps/.
But most of times it is under 60kbps.Never take this connection.If we complaint after 20th date they say these are the last days of month the speed will be increased from 1st day of next month.I will recommend u airtel 4G wifi or new 4G network from reliance known as jio.
