This MMS icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,600 icons, all in the same style and quality.
It is a speech bubble square with rounded corners. Inside of it are 2 triangular mountains (one slightly larger and in the foreground) and a circular sun, somewhat like a stereotypical landscape photo.
