National Wireless Alliance Signs Volume Contract With ITN
For Roaming

Primeco Is First Major PCS Carrier

OVERLAND PARK, Kan. -- The national wireless alliance of
Cellular (AirTouch Communications NYSE: ATI), Bell Atlantic (NYSE:BEL), NYNEX
(NYSE:NYN) and U S WEST NewVector Group (NYSE:UMG), as well as PrimeCo Personal
Communications, signed a bulk contract with Independent Telecommunications
Network Inc. (ITN), to provide Signaling System 7 (SS7) seamless roaming and
enhanced call setup capabilities that make it faster and easier for wireless
customers to use their phones nationwide.

This contract marks a renewal and expansion of ITN's separate
contracts with
each cellular carrier to provide IS-41 transport. "Through joint purchasing the
alliance members will realize roughly a 15 percent savings because of the
contract volume," said Lee Cox, vice chairman of AirTouch Communications and
president and chief executive officer of AirTouch Cellular. "This contract,
like previous handset and equipment purchases, demonstrates the economies of
scale we have created through our alliance."

This agreement also makes PrimeCo Personal Communications the
first major
Personal Communications Services carrier to select a network services provider.
"The ITN network will facilitate roaming among our 11 major markets, enabling
customers to use their phones the same way they do in their home markets," said
Ben Scott, CEO of PrimeCo Personal Communications. PrimeCo plans to launch
service before year end.

"ITN has provided Bell Atlantic NYNEX Mobile with quality
network transport
services for several years," said Tony Malone, Bell Atlantic NYNEX Mobile
Executive Director of Network Planning and Administration. "Now these same
services will be expanded to PrimeCo at a lower cost."

ITN will provide Interim Standard 41 (IS-41) transport and
Services Digital Network User Part (ISUP) trunk signaling for alliance members
over the ITN SS7 network. IS-41 is the industry standard for cellular switch
interconnection and signaling that provides both high speed and

Widespread use of IS-41 signaling has made seamless roaming a
reality, and
allows wireless customers to receive calls automatically without the use of
special codes. It also brings customers the use of the same home market
features, such as call forwarding, when roaming.

ISUP is the call control part of the SS7 signaling that
procedures for setting up, coordinating, and taking down calls using SS7
networks instead of voice trunks. Customers benefit in two ways: first, call
setup -- the time required for the phone to ring after a caller presses the
send key -- is faster, and second, voice trunks have additional capacity due to
more efficient utilization.

"We are especially pleased these industry leaders have placed
confidence in ITN to help them grow in the rapidly evolving wireless
telecommunications market," Ray Donnelly, vice president - Marketing and Sales
for ITN, said. "This is a significant piece of business for us."

The four-way wireless alliance was formed by AirTouch
Communications, Bell
Atlantic, NYNEX and U S WEST in October 1994, to create the broadest market
coverage in the industry. The partners formed PrimeCo Personal Communications,
which successfully bid $1.1 billion for new PCS licenses in 11 major

Combined, the wireless alliance players serve nearly seven
million domestic
customers, operate in 19 of the top 20 U.S. markets, and cover a population
base of nearly 170 million in 46 states and the District of

The new contract with ITN positions this alliance to
eventually facilitate
seamless nationwide roaming between its 800 Mhz and 1900 Mhz markets. As the
Cellular Services Network provider for the Cellular Telecommunications Industry
Association, ITN serves A and B side cellular carriers.

In February, ITN merged with US Intelco Holdings Inc., to form
USTN Holdings
Inc. Together, ITN and US Intelco are the nation's premier independently owned
providers of SS7 network, data base, and message aggregation services, serving
more than 1,000 wireline and wireless telecommunications carriers throughout
North America.
