Dutch-owned German cellco E-Plus has ruled out a merger with Telefonica’s O2 Germany, but it sees room for cooperation in the field of network operations, reports Thomson Financial News, quoting E-Plus CEO Thorsten Dirks. Speculation has emerged in recent weeks that the Spanish giant Telefonica might be interested in a tie-up with E-Plus to strengthen its German mobile phone unit O2. ‘There are no talks taking place with Telefonica,’ Dirks said, adding that previous moves regarding a merger of O2 and E-Plus had all failed. With regards to working together, Dirks said, ‘I invite O2, so that we can do more together…There have been talks over a cooperation in the area of network operations some time ago.’ Dirks went on to rule out the possibility that E-Plus would build its own DSL network or acquire a fixed line company. ’I still see no necessity to enter the fixed line business,’ he said.
