Three has completed £400m of investment in its network with 12,400 masts now spread across the UK.
The operator now claims to provide 3G coverage to 97% of the population.
Three’s network upgrade comes at a time of increasing pressure as data use surges across the board. Part of this growth can be attributed to mobile broadband’s popularity, in part led by Three, the operator said at an event in London last night.
Three has 1.4 million mobile broadband customers and a 37% share of that market. The operator’s sales and marketing director, Marc Allera, said: ‘We are proud that we have led mobile broadband growth.’
Meanwhile, Three revealed that 90% of its sales are now smartphones – a figure that has tripled in just a few months.
To mark its coverage milestone, the network is launching an augmented reality app (pictured) to allow retail staff to demonstrate the work.
The app, which can be used on Android and the iPhone, highlights where the new masts have been added.
Three claims to carry more than 100 terrabytes of data across the network every day.
Three CEO Kevin Russell said: ‘A huge amount of work has gone into taking our network from 7,500 sites to a 12,400 strong 3G network.
’Our customers now receive a depth and breadth of coverage that leads the market. This is the single biggest change in the seven years of Three’s existence and I want to thank everyone who has helped make it happen.’
