Apart from improving internet access and speeds (i.e. bringing Infinity to smaller towns instead of providing even faster speeds to towns that already have it) they could do with improving mobile access.
It is crazy that even in a small commuter town an hour out from central London we have trouble getting 3G let alone 4G. It is impossible to access the internet or mobile banking apps or emails on less than 3G.
Even on the main A road to Stansted airport you may get a signal between laybys but no signal where the layby is. When working as a rep I would come out of a client and not be able to connect my tablet to the internet and have to drive to another nearby town to get a signal. These are the things that hold back business and if we want mobile banking then FinTech companies need to press for improvements in our phone network and support the calls for national mobile roaming.
