Most of the Vendors of telecom services adopt the "Gather first and then screw policy". They first market their product for lowest prices, and once customers are used to their services and they find that its difficult to move to other services, they start raising prices. even if the prices are not raised, network congestion is an obvious issue. I saw a live example in chennai. One of my friend had a Hucth GSM connection as it was the cheapest when he bought it(GPRS - 99 pm, 9-9 calls at 10 paise pm etc.). But due to this fall of rates, most of the people started moving to Hutch leaving Airtel and Aircel. Consequently network congestion came in. My friend lost 2-3 business deals just because the call was cut in mid or the voice was not clear when he was talking to his customers, which caused him a drop off of around 2 lacs. He then wanted to switch to Airtel which provided congestion free services but with some more cost(which was now fine for him). But as portability is not possible in India and he had already circulated his number all over, he couldn't do that. He ended up banging his head on the walls and finally switched to Airtel which was again going to earn him a great loss..
