Meaning
The word FREE in capital letters on a square button. It means free of charge, and in chat it can also mean available or free from obligations.
Shops use it for giveaways, free shipping and free gifts, and friends use it to say they have time: “Saturday afternoon 🆓, coffee?” It pairs with 🎁 for gifts or 🙌 for freedom after exams. The Japanese 🈚 button carries a similar no-charge meaning.
