A recent Ofcom report suggested 20% of homes in urban areas struggle with poor 4G phone signal.
In rural areas, it's as high as 80%. Little wonder then Britain languishes at 54th place in the global league table of 4G connectivity, behind Albania, Estonia and Peru.
The hunt is now on for test beds to develop new 5G technology - Bristol, Kings College London and the University of Surrey are all said to be interested.
The government has announced a fresh drive to bring us up to speed for the digital age. It has put superfast connections at the heart of its Industrial Strategy, backed up with investment of £1bn.
Inside the Smart Internet Lab at the University of Bristol - I discover just how much progress they've already made.
They've designed a small box that emits 5G. The promise is super-fast, super-reliable connectivity wherever you go.
It's an essential component in the driverless car technology they're also working on here. When you're travelling at 60mph in a car reliant on mobile signals for direction, you can't afford to slip into a digital desert.
Lab director, Professor Dimitra Simeonidou, said: "5G is a revolution. It's not just about having a faster connection in our mobile phones - it's also about creating a seamless connectivity with the network and it's about having complete reliability."
"Often in your home you have great connectivity. Your teenagers might be on YouTube while you're watching programmes streamed on iPlayer. Then you get into your car and you don't even get a 3G service. 5G will stop all of this."
As our data demands climb exponentially we need a network that can support them. Now the race is on to design the framework for that digital dream.
