The October-December quarter is a festive period that offers big opportunities to both sellers and buyers. Companies seek to increase revenues and profits through higher volumes. Consumers look for hefty discounts and attractive deals. This wasn’t true, however, for the telecom sector this time. Saddled with huge dues due to a recent Supreme Court order, telecom players stare at a financial abyss that can cripple or bankrupt them. Mobile users can forget about the good old days when they were hooked to free or low-cost calls, text and data. The four major telecom firms—Airtel, Vodafone-Idea, Reliance Jio and the state-owned BSNL—will hike tariffs this December. They did it in 2018 too, but the increases this time will be higher.
