As of today, Cox Communications' wireless service is available across the company's entire California footprint, which now includes the San Diego and Santa Barbara areas.

Cox previously trialed and launched the service in Orange County, Calif. With the addition of California, Cox's "Unbelievably Fair" mobile phone service is now available in Omaha, Neb.; Oklahoma City and Tulsa, Okla.; Rhode Island; Hampton Roads, Roanoke and northern Virginia; and Cox communities in Connecticut and Cleveland, Ohio.

Cox's stated goal is to have the service available in more than 50 percent of its overall footprint by year's end, and on that note, it has rollouts in the works in Topeka and Wichita, Kan., and most of northwest Arkansas.

"Beginning today, Cox Wireless is now available across our entire California footprint," said Kelly Williams, Cox's vice president of wireless products and operations. "In Orange County and across our wireless markets, customers are responding very enthusiastically to Cox Wireless. We are excited to bring our unbelievably fair approach to wireless to consumers in San Diego and Santa Barbara."

After a trial run in Cox's Hampton Roads, Omaha and Orange County systems that started in 2009, Cox launched its Unbelievably Fair service on Sprint's 3G CDMA EVDO Rev A network in those same three markets in November of last year.

In May, Cox announced it was dropping the build-out of its own 3G network to instead focus on offering its mobile broadband and phone services through its wholesale agreement with Sprint Nextel.

In March, Stephen Bye, Cox's vice president of wireless and the point man for Cox's wireless launches on Sprint's network, left the company to go work for Sprint. Cox subsequently promoted Williams to vice president of wireless product and operations in April.
