Antitrust officials at the U.S. Justice Department said they have “grave concerns” about plans by T-Mobile US to shut down the wireless network used by millions of Boost Mobile customers.

T-Mobile operates the 3G network known as CDMA that’s used by Boost.
“The Division is left with grave concerns about the potential for a nationwide CDMA shutdown to leave a substantial proportion of Boost’s customers without service,” the acting head of the department’s antitrust division, Richard Powers, wrote to Dish and T-Mobile in a July 9 letter.
