mms maybe.... or u can also download the "Whatsapp" in which u require internet connection... and through which u can communicate with ur known's free of cost and u can also share pics,videos,and audios too through that!!! :)
Go to photos the click on a photo. Then you should see like a square with an arrow icon on the bottom. Click on it, then it should have 8 or 9 options. One of them is by sharing it in message. Click it, and it puts the photo in your message and you're ready to send!
