The Fire-Boltt Ring smartwatch allows you to make and receive calls using the speaker and receiver built into the watch. It also includes a dial pad, the option to receive late calls, and the ability to sync your phone's contacts. To enable Bluetooth calling, first connect this watch to the viable app. After the smartwatch has been connected, go to the phone's Bluetooth settings and pair it with the smartwatch. After you've matched, you'll see a message that says "Connected for calls and sound."
