EE's 4G mobile broadband services are now available to more than 80 per cent of the UK population, it has been claimed.
The operator added another 200 towns and cities to its next-generation network in Q4 2014 alone, and more than 350 last year as a whole.
As such, 4G EE services are now available to consumers and businesses in 510 urban centres with a population of 10,000+ nationwide.
Hastings, Worthing, Worcester, Scunthorpe, Crewe, Rugby, Bognor Regis, Stratford-Upon-Avon, Bangor and Llandudno are among the towns to have recently switched on to 4G mobile broadband.
And with its increasing focus on rural areas, EE also activated 4G in more than 1,000 villages and small towns in the last few months of 2014.
This means a total of 3,894 nationwide now have access to super-fast broadband for the first time.
EE is hoping to increase its national coverage level from 80 per cent to 98 per cent by the end of 2015, ensuring more people can benefit from 4G services in the UK.
As well as extending its geographic reach, EE is looking to build its subscriber base.
The company added a record 5.7 million customers to the 4G network in 2014, with 1.7 million in the last two months alone.
This means EE exceeded its target of six million customers in total by the end of the year. It now has more 4G subscribers than any other individual mobile operator in Europe.
"In addition to this significant customer growth, [we] continued to drive record network expansion across the year, as well as introduce more accessible 4G EE plans," EE claimed.
New options included £1 pay as you go packs, and high-spec but low-cost 4G devices such as the EE Kestrel, it stated.
"Many new 4G customers have upgraded from Orange and T-Mobile plans to get the extra benefit of the country’s fastest 4G network," the firm added.
