The senators noted that the four largest wireless carriers including AT&T and Verizon Communications control 98 percent of the market. "Antitrust regulators around the world have consistently blocked four-to-three mergers in the mobile and telecommunications industry, and those who have allowed such mergers have lived to regret it," they wrote.
Separately, T-Mobile Chief Executive Officer John Legere defended the merger in written testimony released Tuesday before a House Energy and Commerce Committee panel hearing. He said the company does not "use Huawei or ZTE network equipment in any area of our network" and will "never" use equipment from the Chinese firms in the next-generation high-speed 5G network.
Legere said the transaction will lead to lower prices and more U.S. jobs, even as opponents argue it will lead to the combined carrier hiking prices and cutting costs.
Legere's testimony says the combined firm's business plan projects "aggressive share increases taken from the industry leaders AT&T and Verizon through its accelerated, enhanced 5G deployment." He said the company plans to "keep the customers weve fought hard to win and win new customers with great quality, lower prices, and more innovative offerings."
Sprint Executive Chairman Marcelo Claure will tell the panel that the combined firm's improved network "will be able to compete for customers who have been reluctant to use Sprint or T-Mobile because of concerns that the quality of their individual networks is not as good as those offered by Verizon or AT&T.
