The operators made their offer on July 12, according to the European Commission.
The body has extended its deadline to issue a ruling on the case to August 3, 2016. It is expected to seek feedback from competitors and other parties before a final decision is made. The concessions were not revealed.
The proposed deal involves a 50:50 joint venture in the country through Liberty Global’s fixed services under the Ziggo brand and Vodafone’s mobile offering.
Liberty Global’s acquisition of Belgium’s Base in February was approved after it agreed to specific conditions tailored around competition.
