Since we pioneered mobile technology with the UK's first call and text, we're constantly looking for the next big thing. So this challenge is about finding the best ideas from the brightest sparks.

All students currently studying at UK universities are invited to enter our fantastic 24-hour challenge. Enter with a friend or in a team of up to five people. We'll set an exciting challenge that you'll answer with an online presentation, blog or video. Don't worry, we’ll be on hand to give you hints, tips and advice. A work placement is up for grabs.
