The only problem is that these biggies like airtel, reliance and a few other when they go to a new area they make sure that any sify or local cable operators cables are brought down from the electricity poles as that gives them a lot of instant business and getting a local cable broadband provider to shut shop is a peice of cake for these companies and I have seen that happen more often then not. Getting permissions from the government authorities is not an option either as it swells costs many folds due to this chronic under the table tradition we have in India.
