I am like MTS. I used MTS networks 1 year ago. mts is a good service provides and network available anywhere in india.
Very good network quality and net speed is very good 2g speed. in my area where when mobile phones became a necessity not most of mobile operators were working I tried every one of them but to avail then someone suggested me to take a MTS sim which I did only to my amusment that it worked pretty good and almost anywhere
