Verizon Wireless was forced to sell the service areas, which are spread over 18 states, to satisfy regulatory conditions of its purchase of Alltel Corp. The areas are mainly Alltel territories that overlap with Verizon's own coverage, but also some Verizon territories and areas covered by Rural Cellular, another carrier Verizon bought last year.
Dallas-based AT&T, the country's largest telecommunications company, was the expected winner of the auction for the assets.
AT&T is getting spectrum licenses, cell towers and 1.5 million subscribers in the deal. Since AT&T phones aren't compatible with Alltel or Verizon phones, these subscribers will need new phones to use AT&T's network.
AT&T said the deal is expected to close in the fourth quarter. After that, it will take less than a year to convert the areas to its own network technology, which will require about $400 million in investment.
The states with areas included in the deal are Alabama, Arizona, California, Colorado, Iowa, Kansas, Michigan, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, South Dakota, Tennessee, Utah, Virginia and Wyoming.
