This mobile operator has not that much of work as its brand TATA.I have tried this network but not satisfied.It shows network issues most of the time.In my case it was at roaming most of the time and at most places.This network is not so versatile in giving offers or in service.Now I have already changed my service provider and I am happy.I have heard from some of my friends that Docomo is giving interesting offers in so low cost, but I could not found that much utility of it so I changed this operator.
