Welcome to Thumb – and your chance to find out what SMS and MMS can do for you. What's SMS? SMS – Short Message Service – allows you to send text to mobile phones. What's MMS? The same, but with pictures.

Here in the UK, we send 55 million text messages a day. On a personal level, SMS allows us to share a joke, say hello or spread an important piece of news quickly and cheaply. It also enables us to receive updates on our team's score or who's number one. In this way, mobile phones become a way of carrying our world around with us – so we can stay in close touch with the people or organisations we care about.

Thumb is your chance to make the most of SMS/MMS. Explore – and find out more.
