You can send a new message through your Apple Watch in three ways — all of which require a nearby iPhone: from the Messages app, from your Friends ring, and from by using Siri.
To send a message from your Apple Watch by using the Messages app, follow these steps:
Press the Digital Crown button to go to the Home screen
Tap the Messages app.
This launches the Messages app, where you can read previously sent or received messages.
To send a new message, press and hold the screen until the words New Message pop up and then tap them.
Alternatively, you can tap the Side button to open your Friends ring, press and hold the screen over someone’s name or face (Digital Touch), and then select whether you’d like to call or message them.
Now you’re ready to start a new message to someone.
Tap Add Contact to select whom to send the message to.
Tap Create Message, which lets you dictate your message.
Again, you have an option for Apple Watch to transcribe your words into text or you can send your message as a voice clip.
To send a message from your Apple Watch by using your Friends ring, follow these steps:
Press the Side button to bring up your Friends ring.
Twist the Digital Crown button to find someone to message.
You don’t need to press the Digital Crown button. You tap the person’s initials or photo seen in the center of the watch — and just wait a second.
Tap the Message icon — the speech bubble icon in the lower right of the watch screen.
This launches the Messages app. But remember, you can only add up to 12 people to your Friends ring through the Apple Watch app on iPhone.
To send a message on your Apple Watch by using Siri, follow these steps:
Lift your wrist and say “Hey, Siri” into your watch, followed by “Message ____ (person’s name or number).”
You can also press and hold the Digital Crown button to activate Siri.
The Messages app opens up and you should see the person you want to send a message to.
Dictate your message by tapping the microphone icon.
Tap Send when you’re done recording your message.
The person you’re messaging with receives the text or audio clip momentarily.
A superfast way to send a message to someone through Apple Watch is to raise your wrist and say “Hey, Siri, message ____ (person’s name)” and then say “______ (message).” Siri shows you the message before you send it.
You can also start a message on Apple Watch and continue it on your iPhone. As you can with calls and emails, it’s easy to transfer messages to your iPhone, where you can pick up right where you left off. Apple Watch is meant for quick interactions, not lengthy ones.
