“We believe that TeliaSonera's marketing campaign is misleading. It combines technologies which are not related to broadband with technologies which are not mobile to give the consumer a false impression,” 3 CEO Peder Ramel said in a statement.
At issue are competing claims as to which company's mobile broadband service has the best coverage. In a marketing campaign to promote its mobile broadband service, TeliaSonera claims to have “Sweden's best coverage”.
However, 3 contends that a number of independent tests have shown that 3's mobile broadband service actually provides the best coverage and performance.
On Thursday, 3 filed a suit with Sweden's Supreme Market Court (Marknadsdomstolen), a specialized court that handles cases related to the questions related to competition, marketing practices, and other consumer-related legislation.
3 is owned by the Wallenberg-family holding company Investor, together the Hong Kong-based conglomerate Hutchison Whampoa.
