Meaning
The handset of an old desk phone, shown on its own as a curved receiver with an earpiece at one end and a mouthpiece at the other. It stands for making or taking a voice call rather than typing.
People put it beside phone numbers, shop hotlines and opening hours, or use it to move a long chat to a call: “Easier to explain by voice, can I 📞 you after lunch?” Next to 📱 it focuses on the act of calling, not the device.
