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 is a Cell Phone icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
