So my first sim was vodafone , and still have . I will say they are good than the other networks like airtel , idea , bsnl etc. There is no issue of network of the vodafone , I have never faced this problem . They take good care of their customers . Yeah, sometimes they activate unknown services and told us that you activated this service while using internet and deduct the balance but they refund the balance after telling them the whole issue . Main point is Offers to customers , always gives the best offers to the customer . Overall , the Vodafone is better than the others .
