I am loving jio just only because of it is giving free data of 1gb per day and unlimit calling all over India. Although I like this tele company but aslo disappointing sometimes for its call dropping problem and server down problem. Sometimes my jio app not showing the exact remaining data of 1gb high speed data. Its internet speed is not real 4g. Speed is equal to 3g speed. Some times it shows VOLTE problem also. Its customer service centre is very good. Its network coverage in our area is fine. Thats why I am loving this jio telecom company for its free services.
