I have taken G Broadband connection in Bangalore , after one of my friend suggested me ( Still I keep on taunting him for that )
You cant depend on this internet connection . It may work for 5 min, then down for next half n hour and again connect back .
Whatever complaint you raise is of no use . They will call you back once connection is restored , and ask you if its working . Thats it . Funny part is it will go again after some time of customer support call.
Please avoid taking this Internet service.
