TyoMmsViewer is a MMS viewer for receiving media files sent to you, and unfortunately your telecom doesn't support MMS. For example, If you are with Lycamobile and receive a MMS, you will see a standard text message with a link to Telstra's MMS site instead. An example text is showed as follows: "You have a new MMS Picture or Video Message. To view your message, go to http://telstra.com/mmsview & enter User ID:6142000000 and Password:0mmvv9 within 14 days" Lastly, this App is open-sourced,
