Reliance Mobile Operator is a very bad operator to have in your phone. It has got very bad network. Their networks are not available in many places. Calls get disconnected automatically because of bad network. Their customer service is not at all helping and never resolves ones problem. Whenever I tried to contact them they putted me on hold. They deduct your account balance giving some false reasons. Its charges and billings are cheaps. But it is of no use if we are not able to use it fully.
