How Do I Turn On Emojis On My iPhone And iPad?
Open the Settings app on your iPhone or iPad and navigate to General > Keyboard. Look for the section that says Keyboards and tap on that to see a list of each installed Keyboard on your iOS device. Tap on Add New Keyboard and then select Emoji from the list.
From now on when using your iOS keyboard, a globe icon will appear in the bottom row. Tap that to access the Emoji keyboard. Tap it again to return to the default keyboard.
