People who trade-in a mobile phone and replace it with a device that is operated by either Orange of T-Mobile could be in a good position to benefit from top-quality internet coverage.
The networks, which recently merged to form Everything Everywhere, have unveiled more than 12,000 extra 3G sites ready to be used by mobile broadband customers.
This follows three years of work and significant investment by the firms and Three, which was a joint partner in the venture.
As well as the 3G sites, new transmitters and other equipment that is linked to existing networks will give a boost to those using the internet while on the move.
Among the most significant advantages of the project are an increase in depth and capacity of web provision in towns and cities and an extended reach across rural areas.
Three has been named by the last two YouGov polls on the subject as the UK's best operator of mobile broadband services.
