AT&T plans to acquire Nextel Mexico for $1.875 billion in an effort to create a massive North American Mobile Service area that will be able to offer wireless access to 400 million people. The news comes a few months after AT&T announced plans to buy another Mexico-based wireless carrier, Iusacell , for $2.5 billion.

Nextel Mexico has three million customers and its network covers 76 million people, according to AT&T. The company added:

Combining Nextel Mexico with Iusacell will allow AT&T to more quickly improve and expand its mobile Internet service to the benefit of millions of Mexicans, particularly those who live outside major metropolitan areas, than it could otherwise do without the transaction.

The deal is expected to close sometime in mid-2015.
