Only 16 per cent of East Yorkshire is covered by 3G phone signal, the Bridlington Free Press can reveal.
Almost two thirds of Yorkshire remains uncovered by basic mobile phone coverage, as Government investment continues to be delayed.
Across the region families and businesses are being denied access to the now standard 3G phone signal.
The latest Ofcom figures show that when coverage is measured geographically, some parts of Yorkshire are almost entirely without 3G or 4G reception.
The East Riding of Yorkshire came in as one of the worst areas for mobile phone internet accessibility, with only 16 per cent of the county receiving 3G reception and one per cent receiving 4G.
Most cities throughout Yorkshire are at near 100 per cent coverage. Ofcom said the rural figures rise when counting premises covered, but the lack of a wilder rollout threatens to undermine a Government promise to bring an end to rural so-called “not-spots”, where there is no coverage.
The figures come as it emerges that just two phone masts have gone us as part of a £150m infrastructure project first promised in October 2011.
With one mast in Weaverthorpe in North Yorkshire and one in North Molton, Decon, ministers at the Department of Culture, Media and Sport have pushed back a target of 60,000 new homes covered by the project to 2016.
Countryside Alliance head of policy Sarah Lee said: “Bad rural mobile phone signal is the black hole of the digital age and this is unacceptable. Customers pay a premium price for a service they just don’t receive.
“Despite vote-winning promises of improvement from politicians, there has been little or no improvement on the ground.
“We are campaigning hard on this issue and for better broadband in the countryside, which is a central part of our General Election manifesto, because families and businesses should be able to take good service for granted and at present that just isn’t the case.”
Internet access in general is also an issue for residents living in more rural areas and villages around Bridlington and the East Riding of Yorkshire.
