O2's 4G mobile broadband network is now accessible to 45 per cent of the UK population, it has been claimed.
This is up from 41 per cent in April, when the service provider gave its previous update on next-generation mobile coverage.
According to O2, consumers can now take advantage of super-fast mobile broadband services in more than 240 towns and cities across the UK.
The firm has ambitious targets for 4G over the next few years.
It is planning to invest £1.5 billion in a bid to extend mobile connectivity to 98 per cent of the population (indoors).
Derek McManus, Chief Operating Officer of O2, said the company has spent the past year rolling out its 4G network, in order to connect customers to the products and services they are passionate about in today’s digital age.
"It’s been the fastest build of any new network in our history - just one year after launching 3G we had reached 16 per cent of the UK population," he stated.
"In the same timeframe, we already reach over 45 per cent of the UK population with 4G."
