Jio comes first in my Favorite networks because its network is quite good. when I go to my village, then no network can be found, except for JIO network .
jio customer service is also good. he listens to our complaints and immediately solve them.
the worst thing about the jios customer service is that it has to make phone call to talk to them .
as far as billing and charging of jio is the cheapest and affordable in the rest of the network.
