Sending Text Messages on Your iPhone 6s or 6s Plus
Tap the Messages icon on the iPhone’s Home screen to launch the Messages app, and then tap the little pencil-and-paper icon in the top-right corner of the screen to start a new text message.
If your iPhone is a 6s model, you can press the Messages icon and use the quick action to open directly to three recent conversations or a new blank message. And if you’re not in the habit of pressing Home screen icons, you should be — many offer quick action shortcuts that let you open the app and perform an action with just a single press.
At this point, the To field is active and awaiting your input. You can do three things at this point:
If the recipient isn’t in your Contacts list, type his or her cellphone number or email address (iMessage users only).
If the recipient is in your Contacts list, type the first few letters of the name. A list of matching contacts appears. Scroll through it if necessary and tap the name of the contact.
The more letters you type, the shorter the list becomes. And, after you’ve tapped the name of a contact, you can begin typing another name so you can send the message to multiple recipients at once.
Tap the blue + icon on the right side of the To field to select a name from your Contacts list.
A fourth option is available if you want to compose the message first and address it later. Tap inside the text-entry field (the white rectangular area just above the keyboard between the camera icon and the microphone icon) to activate it, and then type your message. When you’ve finished typing, tap the To field and use one of the preceding techniques to address your message.
When you’ve finished addressing and composing, tap the Send button to send your message on its merry way. And that’s all there is to it; you’ve sent a text message.
