TeliaSonera to be the sole provider of fixed and mobile telephony services to Skanska in the Nordic countries

STOCKHOLM, Sweden, Aug. 31, 2004 (PRIMEZONE) -- TeliaSonera has signed a three-year Nordic frame agreement with Skanska on the provision of both fixed and mobile telephony services in Sweden, Norway, Denmark and Finland. The value of the agreement is approximately SEK 240 million.

The agreement concerns both fixed and mobile telephony services in all the Nordic countries, and it makes TeliaSonera the largest provider of telecommunications services to Skanska.

As a result of the agreement, TeliaSonera wins a completely new account in Denmark, wins back Skanska's mobile services in Sweden, and expands its customer relationship with the Group in Finland and Norway.

"We are very pleased with the agreement with Skanska. This is the first time that TeliaSonera signs an agreement on the provision of both fixed and mobile telephony services in all the Nordic countries," said ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇▇▇, Group Vice President, Marketing, Products and Services, TeliaSonera AB.

"This is the first time Skanska enters into a pan-Nordic agreement with a telecommunications operator. TeliaSonera satisfies Skanska's demands and has the products and services we need in the entire Nordic market. The agreement allows us to cut our costs, which is something we are intensively striving for in general," says ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Head of IT Infrastructure, Skanska AB.
