JIO 4G is a good service
Free call, data unlimited, voice call free and more but disadvantages is jio sim is not supported in 3G phones actual it should support all device even normal mobile for call or SMS this is the biggest disadvantages of jio .I have jio sim but I cant use it because just after I buyed my phone jio have released it sim with free data, call more.but there are some 3G mobile which support jio sim . but good about jio is when company released it's 4G device with just Rs: -3000 with volte and many other support.Then other company now started giving 4G device in low range like samsung , xiaomi, and other many company.
