I was purchased and used JIO when they are releasing in Chennai. It was so amazing and outstanding performance in their network side. Because it was the product from very known "RELIANCE".
However, I am personally feel that the network and service(technical) was so good, and the only thing is they are changing tariff, usage as well as terms and conditions without any prior notification. When you go the store to purchase then only you know the fact. Otherwise you don’t know their actual of RELIANCE. Even their direct show room professionals also give you proper fact.they promote them through all medias. That is the only think I thought. If they correct it. it will welcome.
