The European Commission (EC) accepted changes proposed by Deutsche Telekom and PPF Group to a network-sharing agreement sealed between their respective subsidiaries in the Czech Republic, ending a six-year investigation.
In a statement, EU competition chief Margrethe Vestager noted the commitments offered by the companies had now been made legally binding under antitrust rules.
She added the pledges "will keep the benefits of network sharing whilst removing technical and financial disincentives to unilateral deployments and limiting information exchange."
