Several National Trust and English Heritage sites have also received a 4G boost, from the ruins of St. Augustine's Abbey in Canterbury to the scenic Shieldaig Island, hidden in the Scottish Highlands at Loch Torridon.
Along with this 4G data boost, O2 continues to launch its next generation 5G service, which can transfer downloads to phones at more than 300 Mbps.
The O2 5G signal is now in 60 cities with more than 300 popular destinations in the UK – including Covent Garden in London and the ruins of the Jewry Wall in Leicester – capable of accessing that momentum.
Speaking about the update, Brendan O'Reilly, chief technology officer at O2, said: “It has never been more important for people to stay connected. We have a collective responsibility to help rebuild our nation, and the telecommunications industry is at the forefront of this effort.
