Three has announced that eight UK towns and cities will gain access to its new 4G mobile broadband network by the end of 2013.
Back in August, the service provider revealed that 4G services would launch in London, Birmingham and Manchester before the end of the year.
This comes after Three paid £225 million for a share of the 800MHz radio spectrum band auctioned off by media regulator Ofcom in the spring.
But Three has now confirmed that five other urban centres will receive a 4G upgrade before the end of the year.
Consumers and businesses in Reading, Oldham, Dudley, West Bromwich and Wolverhampton will also be able to connect to Three's 4G network by December.
In addition, the firm has named the towns and cities set to be added to its 4G network in 2014. By the end of next year, the firm expects to offer super-fast mobile broadband in a total of 50 locations.
4G services are to launch in Aberdeen, Blackpool. Bolton, Bournemouth, Bradford, Brighton, Bristol, Cambridge, Cardiff, Coventry, Derby, Dundee, Edinburgh, Exeter, Glasgow, Gloucester, Huddersfield, Ipswich, Hull, Leeds, Leicester and Liverpool.
The other towns and cities set to be added to Three's next-generation network in 2014 will be Luton, Milton Keynes, Newcastle, Northampton, Norwich, Nottingham, Oxford, Peterborough, Plymouth, Portsmouth, Preston, Sheffield, Slough, Southampton, Southend, Stoke, Stockport, Swindon, Watford and York.
Three says that by the end of 2015, it will cover 98 per cent of the UK population with super-fast mobile broadband.
"We already have the fastest 3G network in the UK, and when we start to roll out 4G later this year we'll be even faster," the broadband provider claims.
"When 4G arrives in your area we will nudge you up with a simple free software update. So long as you have a 4G-ready device, you won't pay a penny extra."
