Communicate by images. It's simple.

The Multimedia Messages service offers to all Orange customers the possibility to communicate through pictures, besides voice and text.
If you are either a subscriber or a PrePay user, this service allows you to send and receive messages containing animated coloured photos or pictures, along with texts and sounds, to and from all national mobile phone networks clients who have the multimedia messages service and the mobile phone correctly configured.

You can even make your own photos or you can use an existing picture.
You can attach to it sounds from your phone or sounds you record (your own voice, radio songs etc.), and your text messages can become true letters, reaching 3000 characters, i.e. 15 times more that text messages.
It all depends on your multimedia compatible phone model.
