What’s the difference between a multimedia messaging service and a short message service?
Multimedia Messaging Service (MMS) is an extension to the Short Message Service (SMS) or text message. SMS limits the amount of text characters you can use per message to 160 characters – you can of course use more than 160 characters in SMS if you wish, but you will be charged for more than one message if you do. MMS messages can include more than 160 characters as well as an image plus video or audio files. Both MMS and SMS enable the sending of messages between mobile devices, smart phones etc.
