T-Mobile takes aim at competitors with new deals

T-Mobile has vowed not to unexpectedly increase customer rates, continuing a string of promotions aimed at drawing subscribers and catching up to larger competitors.

"I'm going sign a contract to every customer that says your data plan and your rate will not go up, the fixed plans, while I'm here," T-Mobile CEO John Legere told CNBC's "Squawk Alley" on Wednesday from the company's "Uncarrier" event.

Giants AT&T and Verizon currently account for 87 percent of wireless revenue from businesses. Legere's tenure, which started in 2013, has been marked by promotions and discounts meant to shift from traditional telecom practices and draw new business.

"The number one core thing here is to change that industry," Legere said on Wednesday.
