Ensuring Outstanding Communications Experiences

Even though growth in data use has significantly increased traffic across our network, we kept pace with that growth and received our twelfth consecutive award for wireless call quality from J.D. Power and Associates in 2011, and received our thirteenth award in early 2012.

In conjunction with our partner, King Street Wireless, we also prepared our
4G LTE network and devices to support demand for data services and provide faster and more satisfying data experiences, while significantly reducing the cost to carry data traffic.

We also added capacity to our 3G network and strengthened overall network capacity and coverage by adding 237 new cell sites.
