Regarding the amount paid towards spectrum, there are two ways to look towards it. Some will think ...... aaaw .... thats so huge. But on the other hand the spectrum they have got is for 20 years. Also the biggest part is just have a look at the revenue they are generating from the existing 2G circle. No body is looking at that.If there operating profit is in thousands of crores in a given Quarter, then i don't think they are heading towards bankruptcy, rather I don't know how many users will go bankrupt if they keep sticking to Airtel 3G.
