Plateau Wireless of eastern New Mexico has agreed to sell their network, licenses and customers to AT&T. Plateau has very good coverage and for current customers, service will probably get better. While wireless under AT&T will be a bit more convenient, local users will lose any 'bundle' discounts with the local telephone companies' other services.
AT&T previously had very poor coverage in New Mexico and this, along with their Alltel acquisition, improves coverage significantly. This is fairly unpopulated territory but it includes some I-40 and I-25 coverage. Plateau's associated telephone cooperatives will continue to offer their other communications services and will probably do it better with a little AT&T money in their pockets.
