I belong to rural area where 4G was not introduced about 1 year ago. but due to jio 4G was introduced in our area with very good network quality and best speed ever. Its volte is the best way to call. it improves the quality of calling. It offers very good services in very affordable price. It is cheaper than other mobile operators. Jio 4G is the best 4G which I have ever used. Everyone should use and test Jio 4G
