BBC News By Mary-Ann Russon image copyrightVodafone Vodafone is teaming up with Google to develop a cloud-based data platform to help telcos find new opportunities and improve relationships with customers. Numerous studies have found that telcos are increasingly struggling to find new revenue streams, despite investing heavily into 4G and 5G networks. The partnership is the latest trend showing a convergence between the telecoms market and Silicon Valley. But there are concerns over where in the world customer data is processed. The deal is set to last for six years and will involve a collaboration of up to 1,000 staff from both mobile operator Vodafone and tech giant Google, located in the US, Spain and the UK.
