Activating your new iPhone 8 on AT&T's network is a straightforward process that ensures you can start enjoying your device's features right away. This guide will walk you through the steps, from checking compatibility to completing the activation process.
Before You Begin: Check Compatibility
Before you start, ensure your iPhone 8 is compatible with AT&T's network. The iPhone 8 supports AT&T's 4G LTE network, including bands 2, 4, 5, 12, 14, 18, 19, 23, 26, 29, 30, 38, 39, 40, 41, 66, and 71. You can check your device's model number and IMEI to confirm compatibility.
What You'll Need
To activate your iPhone 8 on AT&T, you'll need the following:

- Your new iPhone 8
- An AT&T SIM card (if you're switching from another device)
- Your AT&T account credentials (username and password)
- Access to a Wi-Fi network
Insert Your SIM Card (If Necessary)
If you're switching from another device, you'll need to insert your AT&T SIM card into your new iPhone 8. Using the SIM eject tool (or a small paperclip), press into the small hole on the side of your iPhone to eject the SIM tray. Insert your SIM card, ensuring the gold contacts face down, then push the tray back into place.
Turn On Your iPhone 8
Press and hold the side button (or the top button on iPhone 8 Plus) until the Apple logo appears. Follow the on-screen setup instructions to set up your iPhone. When prompted, connect to a Wi-Fi network.
Activate Your iPhone 8
During the setup process, you'll be asked to activate your iPhone. Here's how:
- When prompted, tap on "Use Current Plan" if you're keeping your existing AT&T plan, or "Choose a Plan" if you're switching plans or adding a new line.
- Sign in to your AT&T account using your username and password.
- Follow the on-screen prompts to complete the activation process. This may take a few minutes.
Transfer Your Data (Optional)
If you're switching from an older iPhone, you can use the Quick Start feature to transfer your data wirelessly. Make sure both devices are powered on and connected to Wi-Fi. Place your new iPhone 8 near your old iPhone, and follow the on-screen instructions to transfer your data.
Set Up Your AT&T Account
Once your iPhone 8 is activated, you can set up your AT&T account on the device. Download the myAT&T app from the App Store, or sign in to your AT&T account using the browser. Here, you can manage your plan, pay your bill, and access other AT&T services.
Congratulations! You've successfully activated your iPhone 8 on AT&T's network. Now you can start exploring your new device's features and stay connected with your friends and family.
