Activating a new phone with AT&T is a straightforward process that can be completed in a few simple steps. Whether you're switching from another carrier, upgrading your current plan, or activating a new line, this guide will walk you through the process.
Before You Start
Before you begin, ensure you have the following ready:
- Your new AT&T phone
- Your AT&T account information (username and password)
- Your SIM card, if you're using one
- Access to a Wi-Fi network
Step-by-Step Guide: Activating Your New Phone
Method 1: Activating Online
Activating your new phone online is the quickest and most convenient method. Here's how:

-
Go to the AT&T activation page.
Sign in to your AT&T account using your username and password.
Follow the on-screen instructions to activate your new phone. You'll need to provide the IMEI number of your new phone, which can be found by dialing *#0# on your phone or by looking in your phone's settings.

Once your phone is activated, you'll receive a confirmation email from AT&T.
Method 2: Activating Over the Phone
If you prefer to activate your phone over the phone, follow these steps:
-
Call AT&T's customer service line at 1-800-331-0500.
Follow the voice prompts to reach a customer service representative.
Provide the representative with your AT&T account information and the IMEI number of your new phone.
The representative will guide you through the activation process and confirm once your phone is activated.
Method 3: Activating In-Store
You can also activate your new phone at an AT&T store. Here's what you need to do:
-
Visit your nearest AT&T store. You can find the location using the AT&T store locator.
Bring your new phone, your AT&T account information, and your SIM card (if applicable) with you.
An AT&T representative will help you activate your new phone. They will need your IMEI number, which can be found by dialing *#0# on your phone or by looking in your phone's settings.
Once your phone is activated, the representative will confirm this with you.
Transferring Your Data
After activating your new phone, you'll want to transfer your data from your old phone. AT&T offers several methods for this, including:
- Using AT&T's Content Transfer service to transfer contacts, photos, and other data wirelessly.
- Using a USB cable to connect your old phone to your computer and transferring data using a file manager or a third-party app.
- Using cloud services like iCloud, Google Drive, or Dropbox to backup and restore data.
Remember to backup your data before transferring to avoid any data loss.
Setting Up Your New Phone
Once your phone is activated and your data is transferred, it's time to set up your new phone. Here's a quick guide:
-
Turn on your new phone and follow the on-screen instructions to set up your language, location, and Wi-Fi network.
Sign in to your Google account (if you're using an Android phone) or your Apple ID (if you're using an iPhone). This will allow you to access your apps, emails, and other data.
Download and install any necessary apps, such as your AT&T account management app.
Customize your phone's settings, such as your wallpaper, ringtone, and notification settings.
That's it! You've successfully activated your new phone with AT&T and set it up. Enjoy your new device!
