Compare between India's top 4 mobile operator's offers and download speed

After jio launch in India, India is no.1 rank for data uses because its free offers. Jio is so successful mobile operator only few days and it has crossed 100million/10cores customers under 6months. Jio's free offer effected others mobile operator company in India. They have faced great loss in this business. But now the end of jio's free offers only few days remaining and jio has launched its plans. Then the other operators has been launched there same type of plans. I think jio is the best for its cheap rate plans.
Vodafone give us national roaming free incoming call and now Airtel give this offer start 1st April 2017. So, when you are in roaming there is no charge for incoming call but when you try to outgoing call then the outgoing call charge Rs.1.15/min cut your balance. Jio give us full national roaming free like no extra charge for incoming call, outgoing call, sms, data all over in India.
