Idea of Cell Phone Icon
It's a picture of an old school cell phone. Or it could be considered to be just a modern land line. It just has nine black dots for the keypad, a small rectangle for the screen, and a smaller rectangle for the antenna.
This Cell Phone 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 6,200 icons, all in the same style and quality.
