Southwestern Bell Launches New Wireless Service in Tulsa

Digital Network and Handsets are first of their kind in the United States

Tulsa, Oklahoma, May 22, 1997

Southwestern Bell today took another step toward becoming the premier single-source telecommunications provider in Tulsa by launching a state-of-the-art wireless service, called Digital PCS.

Using the first commercially available network and "smart" handsets of their kind in the United States, Southwestern Bell is providing Tulsans with leading-edge, on-the-go communications.

"For many years, consumers and businesses in Tulsa have known and trusted Southwestern Bell for high-quality local phone service," said Mary T. Manning, president and chief executive officer of Southwestern Bell Wireless. "Now, we're launching a wireless service that provides overall value and meets the wants and needs of Tulsans'.

Southwestern Bell's Digital PCS service in Tulsa employs the first commercially available 1900 MHz IS-136 TDMA network in the United States. The service offers Tulsans several distinct advantages, such as:

Southwestern Bell is the first wireless carrier in the country to offer "smart" handsets that allow customers to talk virtually anywhere in the United States - regardless of whether they are calling from a PCS or cellular market. The handsets automatically switch between digital and analog radio frequencies depending on a customer's location when placing a call. The handsets also are equipped with Intelligent Roaming Database software. When consumers make calls outside the Tulsa area, the software automatically searches for the wireless provider that offers the best value.

Southwestern Bell's wireless service includes an 85,000-square-mile home calling area, which runs from Tulsa to Oklahoma City to Dallas and includes most of Arkansas. Depending on the rate plan, consumers do not pay long distance or roaming charges when calling in this area.

"We are delighted to enter the Tulsa wireless market with a wireless service that provides these remarkable features and sound quality," said Adam Vital, vice president and general manager of Southwestern Bell's wireless operations in Tulsa. "Southwestern Bell has a long history of doing business in Tulsa, which gives us a unique understanding of the needs of the local marketplace. We will continue to focus on serving Tulsans and, as always, continue to serve the communities in which Southwestern Bell does business."

Southwestern Bell opened a regional office in Tulsa and hired more than 50 people to help launch its Digital PCS service. In addition, a Southwestern Bell store opened recently in the Woodland Hills Mall.

Southwestern Bell makes wireless simple by including "anytime" minutes on all consumer rate plans. With anytime minutes, customers do not have to plan their telephone calls around "peak" and "off-peak" times of the day. In addition, Southwestern Bell is offering a variety of affordable rate plans and value-added features. Some packages are available without a contract.
