It marks cinemas, libraries, and quiet spaces, the polite rule to put the phone away.
In texting, 📵 does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and 📵 is not really one of them.
Its official Unicode name is the No Mobile Phones emoji. In everyday chat most people just call it the no mobile phones emoji or describe what it shows. Copy and paste it from the button at the top of this page.
