The offers come on the heels of larger rivals Verizon Wireless and AT&T Mobility both hinting that competitive pressures during the fourth quarter have been higher than expected, resulting in their scaling back some operational forecasts. Verizon Wireless parent company Verizon Communications said that Q4 customer churn was trending higher than expected, and that recent promotions and discounts will impact earnings. AT&T management made similar claims at an investor conference this week, noting that the competitive environment is impacting churn and forcing the carrier to put more money on the table in order to lure new customers.
