Jio launch is such revolution in Indian mobile industry. The preview offer given by Reliance is very eye chatching for everyone. Like many otyers I myself bought Lyf mobile as it was compulsory to get Jio sim earlier. Which is was not a bad deal for me at all. There was great speed in starting ( almost 1 gigabyte downloaded in 10 minutes) . In this way I filled my Laptop’s hard disk and I have to buy an extra external hard disk. So overall Reliance Jio is best to use as free and as heard from Reliance their Data Packs will also be cost effetive as compared to other operators. These days internet speed is little slow due to more connections and it takes to many tries to call someone from Jio, still it is very good to use. Thanks
