An array of companies and groups that have opposed T-Mobile US Inc's plan to buy Sprint Corp recently announced that they had banded together, saying the deal would lead to higher prices for wireless customers and hurt rural consumers.

The group includes companies like C-Spire and DISH Network , the Communications Workers of America, NTCA-The Rural Broadband Association and advocacy groups like Public Knowledge. In their statement, they asked the Federal Communications Commission to reject the deal.

"T-Mobile and Sprint's vague promises to create jobs and provide better service to rural America do not meet the public interest test for approval of the merger," said Debbie Goldman, research and telecommunications policy director, Communications Workers Association. "The data and the companies' own track records demonstrate how the merger would hurt U.S. workers and consumers."
