By Robert Hetz and Leila Abboud MADRID/PARIS (Reuters) - The battle over Brazil's telecoms market is heating up, with the country's biggest fixed-line firm Oi signaling it may make an offer for Telecom Italia's local mobile business. The move throws a potential wrench into the bidding war for Vivendi's Brazilian broadband unit GVT, which both Telecom Italia and Spain's Telefonica are pursuing to bolster their mobile businesses in the country - number two Tim Brasil and number one Vivo respectively. Brazil's leading telecoms groups are jostling for position as they seek to increase their customer bases and gain ownership of high-speed fixed networks. Oi wants to spur consolidation in mobile, which would reduce the number of operators from four to three and potentially take some of the heat out of the competition - a pattern seen in markets such as Austria, Germany and Ireland.
From now until the end of the year, it expects to double the number of subscribed users in Germany, after growing fivefold so far in 2014, the company said. Currently, Uber is operating in Berlin, Hamburg, Munich, Frankfurt and Duesseldorf. Other German cities are also considering a ban, according to media reports. Uber has faced regulatory obstacles in a number of European cities as well as legal challenges from taxi companies hoping to keep new competition out.
