Customers can access personal accounts, booking and itinerary information, and find detailed hotel information, including reviews, maps and photo galleries.
The mobile site is designed for touch screen mobile phones but is available to any phone with web browsing capabilities.
Tamer Tamer, president, ebookers, said: "With the launch of our mobile site, we have taken a significant step forward in terms of meeting the needs of our customers. And we recognise the increasing importance to shop and book hotels, flight or cars anytime or anywhere for our customers.
"So if you’re on the move or already at your destination, simply take out your mobile phone and you will have full access to our entire inventory.
"That is why we have heavily invested in developing an easy to use, reliable and safe mobile website that allows our customers to do everything they can do on our regular site and continue to book easier and travel happier."
The mobile site is available in different local language versions for the 12 European countries it operates in – Austria, Belgium, Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Sweden, Switzerland and the UK.
Ebookers.com sponsors the celebrity travel programme, 'Trevor McDonald's Secret Mediterranean', which launched on ITV1 last week.
