Three is a little different from the other major UK networks, because all of its contracts come with 4G coverage as standard. EE, O2 and Vodafone have dedicated LTE plans, allowing us to easily gauge the interest in its ultra-fast offerings, but for Three, where any customer can fall into a patch of 4G, it's trickier to quantify. The company has been quiet up until now, but today it's finally shared some figures: since switching on its 4G network a year ago, 3.1 million customers have benefited from the faster speeds. That means over a third of Three's 8 million subscribers have wandered into an area supported by its 4G network, which now covers 48 percent of the UK population. If you're keeping score, EE is out in front with 6 million 4G subscribers, followed by O2 with 3 million and Vodafone with 1.4 million. Although Three's numbers aren't directly comparable, they're still a useful yardstick.
