You can increase your mobile broadband speeds by 40% with a new dongle from Three.
Three's new "premium dongle", the Huawei E367, will allow users to take advantage of the latest technologies such as HSPA+ for even faster web browsing.
David Kerrigan, Three's head of mobile broadband, said: "Huawei has done a great job delivering this superior dongle, in both form and function.
"Whether browsing the internet, downloading files or streaming video, this dongle delivers an even better internet experience on our 3G network, which is built for mobile internet."
The new dongle has the ability to connect at speeds of up to 21.1Mb. "Our network upgrade to 21.1 is underway and will be completed during the year," said Three on its blog.
The Huawei E367 also comes with a "swivel" design that allows you to bend it upwards to reach the best possible signal.
However, a wide number of issues affect mobile broadband signals, and many consumers receive far less than their advertised maximum speed.
For example, when Vodafone announced a network upgrade to 14.4Mb in 2009, it revealed that "customers can expect to see typical speeds of anything between 1Mb and 4Mb with a practical maximum speed of 10.8Mb."
