NASA is currently ramping up its plans to send humans back to the moon under the “Artemis project”, with the aim of having a “sustainable” human presence on the lunar surface by 2028. And as we know, says Mazuma Mobile, one of the most important necessities of modern human life is a reliable mobile data signal!.

NASA has granted Nokia a $14.1 million (€11.58 millon)contract to install the first-ever 4G mobile network on the moon. Once installed, astronauts will be able to carry out a number of activities such as making voice and video calls, as well as sending important data back to Earth via 4G. But with 4G making its way to the moon, and some areas here on Earth already receiving 5G signals, there are still some parts of the UK which struggle to get full 4G.

Mazuma has analysed data from Ofcom’s Connected Nations report to find out the number of UK parliamentary constituencies which still don’t have full coverage from the country’s big four mobile operators, EE, O2, Three and Vodafone.

Out of 650 locations, just 24% have full access to 4G on those four networks, leaving 493 with patchy signals.

The areas with the worst 4G signal include Dwyfor Meirionnydd, Ross, Skye and Lochaber, Ynys Mon, Orkney and Shetland and Na h-Eileanan an Iar (also known as the Western Isles), which has around 50% 4G coverage for the big four networks.

Parliamentary constituency	Region	% of outdoor premises with 4G signal from all four operators
Na h-Eileanan an Iar	Scotland	50.11
Orkney and Shetland	Scotland	62.72
Ynys Môn	Wales	63.52
Ross, Skye and Lochaber	Scotland	69.7
Dwyfor Meirionnydd	Wales	73.11
Montgomeryshire	Wales	75.59
Argyll and Bute	Scotland	76.6
Cynon Valley	Wales	78.77
Ceredigion	Wales	79.78
Penrith and The Border	North West	80.32

As the table shows, these are mostly relatively rural areas, although even some areas in the country’s major cities don’t have a full 4G connection, including Edinburgh South (97.36%), Sheffield Hallam (99.24%).

The figures also show that Scotland, Wales and Northern Ireland suffer the most when it comes to 4G. In fact, just eight of the areas which had 100% 4G coverage were located in Scotland, with just one in Wales (Cardiff Central) and none in Northern Ireland.

On the other hand, 38% of the areas with perfect 4G were located in London, with over half (53%) in the south of England.

Parliamentary constituency	Region	% of outdoor premises with 4G signal from zero operators
Montgomeryshire	Wales	4.13
Na h-Eileanan an Iar	Scotland	3.33
Ross, Skye and Lochaber	Scotland	3.31
Brecon and Radnorshire	Wales	3.21
Newry and Armagh	Northern Ireland	3.13
Ceredigion	Wales	2.61
Argyll and Bute	Scotland	1.93
Dwyfor Meirionnydd	Wales	1.93
Carmarthen East and Dinefwr	Wales	1.86
West Tyrone	Northern Ireland	1.55

It’s also a similar picture when you look at the constituencies which have the highest proportion of places with no 4G signal at all, with more people in Montgomeryshire unable to access 4G than anywhere else. Again, the top 10 is dominated by places in Scotland, Wales and Northern Ireland.

While it’s great that 4G is coming to the moon, it seems that there is still some way to go before the whole of the UK is fully covered by perfect 4G signal.

Methodology

All data sourced from the Summer 2020 update of Ofcom’s Connected Nations report (mobile Westminster constituency).

Specifically, Mazuma looked at the proportion of premises in each constituency which receive 4G from all four major mobile networks (EE, O2, Three and Vodafone), as well as those which receive 4G signal from none of those providers.
