While writing this review I have remembering my journe with airtel, its been a long journey of 12 years, from prepaid to post paid, swiching & porting no. but I always kept one no. of airtel just because even it costs high but it always comes with a good network coverage.
In fight of comptetion with other sevrvice providers it is loosing its USP of good newoking, although charges have came down but still when comparing current service level at same cost it is high.
By the time 4 G has came company has ruinned his 3G services, it some times wok poorer than 3G.
The only thing is good id customer care executive & power they have, if you feel issue they gives you on time solution.
Still I will recommend as at once whatever sevice provide you have keep one airtel, now it has change if you have only airtel keep one more service provider.
