Mobile phone company EE achieved two million customers by the end of 2013 as consumers continued to sign up for 4G.

The firm, who took ten months to pass the one million customer threshold, has managed another million after just four months. It is continuing to roll out its 4G network which will cover 70 per cent of the UK population by January.

EE say the 4G sign-up rate in the UK is the fastest in the world outside of South Korea.

Olaf Swantee, CEO, EE, says: “Our 4G launch in October 2012 marked a new era for mobile users, allowing consumers and businesses to do much more on the move. This year, our network priority is to deliver the benefits of superfast mobile internet to more of the UK and invent even more innovative ways for our customers to make the most of their 4G experience.”

4G‘s price plans, which range from £16 – £61 a month, are popular with new SME‘s as 75 per cent chose 4G as their preferred network. EE will also be investing £275m into improving its mobile call service this year.

Swantee added: “We continue to have particular success converting our existing base to 4G, with approximately two out of three new 4G customers moving over from Orange and T-Mobile plans.”
