Minneapolis St Paul Business Journal reports…

Telecom giant T-Mobile US Inc. (Nasdaq: TMUS) is set to acquire U.S. Internet, the Twin Cities internet service provider that has built a fiber network throughout much of Minneapolis and some surrounding suburbs.

Minnetonka-based USI this month sent a letter to customers announcing that U.S. Internet is joining T-Mobile. “Although the closing date for our transaction has not yet been set, we anticipate that following regulatory approval, you’ll become a T-Mobile customer on or after Sept. 2,” the letter read.

Terms of the deal weren’t disclosed. Officials at T-Mobile and USI couldn’t be immediately reached for comment.

The letter said that USI will be part of the T-Mobile Fiber Home Internet service. The Bellevue, Washington-based company launched its fiber home internet product June 5, a month after T-Mobile and investment firm EQT acquired High Point, North Carolina-based fiber internet provider Lumos.
