Hii friends , I am using tata docomo mobile operator from 2 years . I choose this operator because its call and internet plans are cheaper . When I start using tata docomo operator then I know that its plans are cheap but it not have network . I call many times to customare care but my problems are not solved . Its network is worst , simple text message are also not send from tata docomo operator . Calls , internet are also not working properly . Sometimes it have network in a day . Simple whatsapp messages are also not send . It is a worst mobile operator to use .
