I have been using the Reliance 3G for about 1 and a half years. The nightmarish experience I had using that.
Their connection provided is rotten.
To just show you, Google mail they will take 15 minutes. Sometimes you have shuttle in between 1 and 3 floor to get a connection. It was a push sale and they employ dishonest agents.
I have lodged complaints with the appellate authority and they have given me a number of dockets but with no results.
