Enable the Emoji keyboard. Perhaps you’ve seen these iconographic symbols in emails, iMessages, and tweets, and wondered how the heck people managed to type them. Maybe you’ve mistakenly assumed that you need to purchase a third-party app to gain access to those special symbols.

You don't: Apple treats those symbols, called Emoji, as an international keyboard. Launch Settings, and tap General, International, Keyboards. Then tap Add New Keyboard and find Emoji. Now open an app where you can type some text.

Next to the spacebar, you’ll see a little globe icon. Tap it to switch between your regular keyboard and the Emoji one, which contains many tabs full of different characters. Tap on those characters to insert them wherever you’d like. (If you have many international keyboards, tap and hold the globe to bring up a menu of all your options.)

Spoken Emoji. For real fun, type in a bunch of Emoji symbols, select them all, and then tap the Speak button. You’ll hear the often-entertaining names of each symbol read in sequence.
