Antitrust - Case 29

Coordinated behaviour of mobile telephony operators

Alleged coordinated behaviour of mobile phone service providers. We supported T-Mobile Germany in an investigation by the Federal Cartel Office into an alleged coordination of behaviour between T-Mobile and Vodafone in Germany and the alleged abuse of a dominant position in mobile call pricing. We analysed, inter alia, several structural factors of the mobile-call market with regards to the likelihood of coordinated behaviour and the impact of lower on-net than off-net prices.
