Mobile broadband is occasionally something of a contradictory term, especially when it comes down to using a mobile broadband service while actually moving.
In a test carried out by broadbandgenie.co.uk it was found that T Mobile performed the best out of the six largest providers of mobile broadband services in the UK.
The test took place on a three hundred and fifty mile train journey from Cambridge to Bournemouth and back.
The team tested dongles from 3, O2, Orange, T Mobile, Virgin Media and Vodafone over the course of the trip.
However it was T Mobile that came out on top, achieving a top broadband connection speed of over 3 Mbps, but it averaged 1.9 Mbps over the journey.
Part of the test was to download a 20 Mb podcast file, which took just 22 seconds.
