Telefonica will buy some of the core equipment for its planned 5G mobile network in Spain from Chinese telecoms giant Huawei but also choose a second provider next year, a company spokesman said on Friday. The move, first reported by Spanish economic daily Expansion, marks a strategic shift for Telefonica which previously relied only on Huawei. The Chinese company provided Telefonica's 3G and 4G core networks in Spain.
