An icon representing vibration mode on a mobile phone, indicating that a phone should be switched to silent or vibrate mode. Typically depicted as a white smartphone outline on an orange square background, with curved or zigzag lines on either side to suggest shaking/vibration. 

Google distinctly displays the same detailed black smartphone, as appears in their 📱 Mobile Phone and 📲 Mobile Phone with Arrow Emoji emoji designs. This was also true of several previous Microsoft designs.

Early Japanese versions of this emoji often used a heart alongside a mobile phone, as commonly seen in Japan. This was emulated in the first designs by Apple and Twitter.

Google's early designs for this emoji included a treble clef with a prohibited sign overlaid on it beside a mobile phone. Facebook's initial design displayed a bell with a prohibited sign overlaid, similar to their initial design for the 🔕 Bell with Slash emoji. Samsung's design previously had a green background.

Vibration Mode was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
