After months of aggressive moves by T-Mobile US to lure customers from other carriers, No. 2 operator AT&T Inc counter-attacked on January 3 by offering to pay consumers to switch from T-Mobile. Days later, No. 3 ranked Sprint Corp promised big discounts for family and friend groups. On Wednesday, T-Mobile upped the ante, saying it would pay hefty exit costs for converts. The moves by Sprint and AT&T come after No. 4 U.S. operator T-Mobile, a long-time industry straggler, was able to report three full quarters of customer growth after four years of losses. While discounts are always welcomed by consumers, the intensifying competition is a new challenge to a U.S. industry long used to imposing its will on consumers, and analysts fear it could result in the loss of billions of dollars of revenue. How sad is it that articles such as this are able to be written? Do you mean to say that due to actual competition between the wireless carriers for the first time in years that their record profits are at risk of declining? Ridiculous. Furthermore, how sad is it that Ms. Carew is able to write an article like this couched around the idea that Wall Street is concerned, yet very little mention about how this could be a massive benefit to customers.
