I am using Tata docomo services from last 3 years , though they offer cheap recharges but the service that they offer are one of the worst services that you can ever experience. They show ads like that they provide the really heist services but trust me they don’t . Whenever I visit any city or hill stations eventually their there signal got disapeared while Airtel still got signal . This happened to me everytime I visit any place . Their customer service is like an hell they behave like they are not in mood to help. I suggest you to use jio or airtel rather than using their services
