We have around 50 airtel mobile connections in our factory and more than 100 Will airtel connections and also broadband connection. Im facing lot of problem with Airtel service. Every time i travel abroad, my mobile out going dosen't work, only incoming works. This i repeatedly keep complaining to the local Airtel office here before my trip, but no use. If you ask for an international roaming tariff, the details are avilable in their website. Where as they have tie up with 4 service providers in every country with different attractive tariffs. But once u r in abroad, if you choose the best tariff sevice provider, none will accept your request, Only one service provider will accept your request whose got the highest tariff. Airtel the worst service provider with out any ethics in business other than money... Now we are in a mind to surrender all the Airtel connections and shift to some other service provider.
