Once upon a time I got puzzled for choosing a perfect reliable operator.after using airtel mobile operator I find the solution to my problem.
advantages I got after using airtel mobile operator-
airtel provides strong network signal.
provides app to easily manage your account.
provides high speed 3g and 4g service.
wide ranges of offers according to need.
the main disadvantage of airtel mobile operator is, it’s costlier than other operator.but I think money is a high determining factor not the highest.
