I am living in mumbai for past few months and I have been using Airtel network from more than 4 Years.
Here, in mumbai the network quality is so poor even in a known place network is just low.
My calls either gets disconnected or gets connected very late.
Customer Care does’nt responds properly which is very unsatisfactory.
Still they are providing such expensive recharges.
My friends use Jio they are not hetting any kind of such issue
