Unboxing and Initial Setup
Start by unboxing your new iPhone. Once you've removed it from the packaging, follow these initial setup steps:

Using a Direct iPhone to iPhone Transfer
- On your old iPhone, go to Settings > General > Reset > Reset Network Settings.
- Turn on your new iPhone and follow the setup prompts until you reach the "Apps & Data" screen.
- Tap on "Transfer from iPhone" and follow the on-screen instructions to complete the transfer.
Verifying Your Activation
After activation, you can verify that your iPhone is connected to AT&T's network by checking your signal strength at the top of your screen. You can also check your account details and data usage by signing in to your AT&T account online or using the AT&T mobile app.
Remember, activating your iPhone on AT&T's network ensures that you can make calls, send messages, and access data on your new device. If you encounter any issues during the activation process, don't hesitate to contact AT&T's customer support for assistance.
