I think the argument that "Since call charges are less, they offer pathetic service" Isnt valid here. If call charges were high in the past, then u give me the count of people using Mobile phones then. And even if people "Owned" mobile phones, how many times did they actually "Use" them to make calls.If they made calls, then "What was the duration" of those calls. And also what "Kind" of calls - Local/STD/International.Today, a customer with "Normal" type of usage also makes calls of around 1.5-2 hours a day. U didnt have that in past.People use STD as freely as they use Local calling. Whereas during the times that u talk about, hardly any STD calls were made.Not only that, people use a lot of Data too these days - many people around spend 98/month for getting a measly 2 GB of data.If "Sales Price" has gone down, then their "Product Mix" & "Quantity sold" have gone up considerably.Btw, u do realise that the charges were high in the past as companies were recovering their setup costs of initial laying of infrastructure?
