Vibration Mode emoji is a 📱 Mobile Phone with the vibration symbol. If you have to go into a location where you can’t have your phone’s volume on, like a library, then you might send out this emoji to your more chatty friends to let them know. Or, if you have a forgetful friend, you can send this emoji to remind your friend that they will need to keep their phones volume off. The last thing you want is for your phone to go off, have everyone stare at you, and possibly risk having your phone taken away. Send this emoji along with a 🤫 Shushing Face emoji to show that you or your friend’s phone needs to be quiet. In case someone doesn’t get that you want their phone’s sound off, send this emoji with the Mobile Phone emoji hoping they get what you mean then. (Source: Emojis.wiki, Fair use)
