According to Reuters, Dutch telco KPN has said that Germany’s antitrust authorities have launched an investigation into cellcos T-Mobile and Vodafone for allegedly abusing their dominant market positions. The Federal Cartel Office began its proceedings following a complaint from KPN, which owns rival operator E-Plus, according to a statement from the Dutch company. It added that Belgium’s competition authorities have also found that the country’s dominant cellco Proximus has also abused its dominant market position. KPN operates a mobile network in Belgium under the BASE banner. ‘The actions now taken by the competition authorities both in Germany and Belgium confirm our belief that the dominant providers are engaging in anti-competitive behaviour on both the Belgium and German markets,’ crowed KPN Mobile International’s CEO Stan Miller.
