I think for the very reason that they monopolize the sale of handsets you can use with their service, Reliance and Tata Indicom should be totally avoided. They are only good for the average junta who doesn't care what handset they use as long as it's cheap and the call rates are cheap. (The biggest advantage of Reliance AFAIK is that if most of the people you know are also on Reliance).Is there no other service that gives you a good signal in your area?
