Step by Step – How to Send a Text Message on iPhone 15
Getting your thoughts across to someone else does not have to be complicated. These steps will guide you through the exact buttons to push so you can send your first text in seconds. Following this guide will help you master your new phone quickly.
Step 1: Unlock your iPhone 15 and tap on the green Messages app icon.
This app looks like a white speech bubble inside a green square and is usually found on the bottom dock of your screen. It is the central hub for all your SMS and iMessage conversations. You will likely use this app more than any other on your device.
Step 2: Tap the compose button located in the top right corner of the screen.
You will see a square icon with a little pencil inside it which opens a blank conversation. Tapping this tells your phone that you are ready to start talking to someone new. It essentially clears the deck for a fresh start.
Step 3: Enter the contact name or phone number in the To field.
You can start typing a friend’s name and tap their contact info when it appears on the list. If you do not have them saved, just type out their ten-digit phone number carefully. Make sure you have the correct digits before moving on.
Step 4: Tap the text message field situated above the keyboard.
This area usually says iMessage or Text Message in light gray letters before you start typing. Tapping here brings up the keyboard so you can begin drafting your note. The cursor will blink to let you know it is ready.
Step 5: Type your message and tap the arrow icon to send it.
Once you finish typing your thoughts, look for the blue or green arrow on the right side of the text box. Pressing that button instantly shoots your message through the airwaves to your recipient. It is like dropping a letter in a high-speed digital mailbox.
After you hit that send button, your message will appear in a bubble on the right side of the screen. You will likely see a small notification saying “Delivered” underneath it if the other person also has an iPhone. Now you just have to wait for them to write back to you.
