We are investing £1 billion this year alone, following the £1 billion we invested in 2014,  to improve the strength and resilience of our network across the UK. We’re bringing 4G to new places and using pioneering technology to provide reliable coverage in rural not-spots. We’re upgrading our infrastructure with new masts, pumping mobile data through trains, tubes and some of the tallest buildings in the world, and a whole lot more besides… The network will always be the most important part of our business, and it’s constantly evolving.
