Don't blame Jio if you can't improve your service even though till now Airtel network is not strong in cities after loosing customers.Before Jio there were 8+ telecom companies in India and now its 4 only.During the launch of Jio with freebies many experts predicted there will only BSNL and Jio left in future.Partially it became true and major ones had suffer lot to survive.
People are ready to pay 50 rupees more if you promise to give perfect data speed in all over the coverage like Jio.
