The innovative service will enable the user to get an instant quote when they are away from their computer, for instance, if they are comparing cars at a second-hand-car dealer or filling time while travelling.

Links to the new service will be available on the mobile home pages for Yahoo, O2 and Vodafone, and will be promoted throughout the UK with a national advertising campaign.

Tina Shortle, marketing director at swiftcover.com, said: “When you're considering spending thousands of pounds on a new car, you want all the facts at your disposal and that includes how much it costs to insure. All too often, people end up losing out on a bargain because they don't have enough information to make a decision.

“Our aim is to make car insurance as easy, simple and convenient as possible. By harnessing the next generation of mobile internet technology, we're enabling people to get the facts at their finger-tips and shortening the time and hassle of car insurance quotations.”
