No doubt airtel network is good compare to other networks.but the main issue is if the network goes out then it will take too much time to come back.according to me airtel 4g is good compare to other networks because it reached to rural areas also.
Internet speed-the internet speed of airtel 4g is good.we can trust on this network .it also works on croweded area.in the mode of travelling also it run fine.
connection reliability-the connection reliability is average type on airtel.but compare to other networks its good.
service and support-the worst thing of airtel is its service and support.if your network goes wrong then there is no solution.you must have to visit the office every time.the employee of airtel are no so friendly.if there is any issue and we have to conform it through customer care executive then its impossible to connect.
