AT&T customers in Phoenix and other Arizona cities will now have greater access to 4G LTE service.
According to 9to5Mac, AT&T invested $700 million in Arizona's wireless networks since 2009. This investment will provide the new service in Phoenix, Avondale, Glendale and Litchfield park.
Areas in Nebraska, Texas, California, Kansas and Florida will also be receiving access to the service.
The opening of 4G LTE access to more customers is an effort to reach 300 million customers by the end of 2014.
