I personally like concept of jio free data and callling service but from few month data speed is very poor even sometimes I cant able to send a whatsapp text messages to my friends
If I talj about free calling its worst you can only call onother jio number but you cant connect other operators but its not thier fault other telecom operators are not giveing signal to jio but somehow jio have done really good job we should appreciate thier job
Here is the link how you increase speed of jio data
