How do you use iMessage to send text, pictures, videos, sound, location, and more—right from your iPhone, iPad, or Mac?

iMessage is Apple's built-in instant messaging (IM) service. It lets you send text, picture, video, sound, and location quickly and easily to anyone else using iMessage on iPhone, iPad, Mac, or Apple Watch. Apple has also brought significant updates to iMessage in iOS 10, including bubble and screen effects, emoji tapbacks and full-on emojification, Digital Touch and handwriting, and, for the first time, iMessage apps.

On your iPhone, iMessage lives alongside SMS and MMS, so you can keep in touch with non-Apple friends from the same app. Thanks to Continuity, you can even get those "green bubbles" on iPad and Mac as well! It makes for an incredibly powerful, unified experience. Here's how to use it.

Messages in iOS 10 has new effects for iPhone or iPad that make bubbles slam, loud, gentle, or invisible, or turn the whole screen to balloons, confetti, lasers, fireworks, or shooting stars.

Messages in iOS 10 also takes emoji to the next level. If that doesn't sound important to you, then you haven't seen the kind of cheers emoji get on stage or the amount of interest they generate on social. They're a big, smiley, thumbs-up deal! If you want to test them out, here's how!

Digital Touch — the ability to send a hand-drawn Sketch, haptic Taps, or sensor-read Heartbeats — was one of the debut features of the Apple Watch. Now, with iOS 10, all those communication features are making their way to the iPhone and iPad as well. Will Digital Touch on the phone and tablet come off as a gimmick, or will it go mainstream? If you're a developer, you can try it out now and decide for yourself.

Apple has opened up iMessage to the App Store. Designers can now create sticker packs that you can post send, modify, and stamp on top of other messages. And developers can create apps that let you share content, edit photos, play games, send payments, and collaborate with others, right inside Messages. It's great for users, who get much richer functionality, and for developers, who get a chance to become as viral as the next hot meme.

Before you can start using messages, and sending texts, photos, videos, voice memos, locations, and contact cards, however, you need to set it up. If you enabled iCloud on your iPhone or iPad, there's a chance iMessage was enabled as well. If not, you can turn it on quickly and customize it just the way you like it.

If you stop using your iPhone, though, and switch to Android, Apple has to stop sending iMessages instead of SMS. The best way to make sure Apple knows you've switched, and to make sure you don't miss any messages from those still using iOS, is to turn off iMessage before you go.

With the Messages app, you can send all kinds of things to all kinds of people. You can send iMessages over Wi-Fi or cellular data to anyone and everyone using an iPhone, iPad, Mac, iPod touch, or Apple Watch. That includes text, pictures, audio, video, location, and more. You can also send standard carrier SMS/MMS text and picture messages to anyone on any phone. Here's how!

The Messages app also lets you forward iMessages. You can forward the message to one or multiple contacts, or copy the contents and paste into an entirely new message. Copying is also a great way to get a message into another app, like Mail, Notes, or Safari.

iMessage lets you send more than just text, images, and video. You can also send contact cards, voice memos, map locations, and more. You do have to go to other apps to fetch the information you want to send, but once you're there, the Share Sheet makes it easy to do.

Once upon a time you had to slowly and methodically tap your way through apps and between them just to send and respond to messages. Thanks to the Messages app and Notification Center, though, you can rapidly respond from any app, and immediately send soundbites, selfies, location, and more right over iMessage.

You don't have to send iMessages to just one person. Thanks to groups, you can share text, photos, videos, soundbites, location — almost anything you like — with two people, three people, and more. You can even name a conversation thread to make it easier to find and keep track of, or mute it for when it's getting too noisy to follow.

You can't delete iMessages or SMS/MMS on someone else's iPhone or iPad — so always be careful what you send — but you can delete any record of them from your iPhone or iPad. So, whether you don't want to be reminded of an embarrassing or hurtful text, or you want to get rid of storage-consuming pictures and videos, the Messages app lets you wipe them out or set them to expire automatically.

And just because anyone can send you an iMessage on your iPhone or iPad doesn't mean you have to let them. If you're getting messaged too often, if you keep getting messages meant for someone else, of if — ugh! — you're getting spam, you can absolutely take action again it. Mute, block, and reporting are all here for you.

Whether you're driving or your iPhone or iPad is simply across the room, you can combine iMessage with Apple's virtual assistant, Siri to send texts and even have incoming texts read to you, all with the power of your voice.

Note: Most modern iPhones and iPads can be voice-activated when plugged in. 2015 iPhones and later, and 2016 iPads and later, can also be voice-activated when not plugged in. Simply say "Hey Siri" instead of holding down the home button. All subsequent steps remain the same.

If voice isn't your thing, there are also a variety of gesture shortcuts built into Messages. Not all of them are obvious, but all of them are useful — once you figure them out!
