Thanks to Tata,I am having good browsing speed with Tata with unlimited downloading speed.I am satisfied with their services.
It is TATA internet connection which I am using at my home,the speed and service is good,it is a wireless type,the charges is Rs800 which I feel bit high and costly,but the their network is good.
The response was good from TATA to me.they had told about the plan what they have which was good,one plan was having Rs800 approximately with unlimited service but I felt that high price so I had not taken it,I am in touch with them I may take this service if they offer any cheap plan with good facilities.
