I tried each and every mobile operator but didn’t get satisfied.At the end my father suggested me to take airtel’s service.Trust me just after a couple of days I became fan of it and decided to keep it permanent with me.this company gives too many offers and the network is available almost everywhere.call rates and internet rates are affordable.I must say that it’s internet speed is the best.i don’t even have to say that.you can see its transparency yourself everywhere.the biggest example is tv.
