Having checked about 4 ISP’s, I think, I can rate VSNL at a better rate. Earlier, ie., 3 to 4 yrs back, this was not the scene with VSNL. I was really bugged up with their service. But now, VSNL has really improved a lot. Even in ordinary Dialup connection, you will experience a good speed now.
The scheme with VSNL is really attractive. If you purchase 100 hrs dialup package, it will cost you Rs.750, which is valid for 3 years, during which the service between 11 P.M to 8 A.M and full Sunday is free.
If we talk about Dishnet DSL, I can say that, they are the worst ISP providers on earth. It has got a very very Lousy connection and the speed is really horrible. If you have 24 hours connectivity thru cable line, then your life will be still misserable. One will never know, when the link will be down and when it will be reactivated again. If you are thinking of purchasing with Dishnet DSL, then probably please rethink.
