How Do I Activate Xfinity Mobile?

Activating Xfinity Mobile is a straightforward process that typically takes around 10-15 minutes. If you encounter any issues, don’t hesitate to reach out to customer support for assistance.

Here’s a step-by-step guide:

1. Retrieve your account PIN from your previous carrier, which is necessary for activation. Contact your carrier if you don’t have it readily available.

2. For Apple iPhone 12 or earlier models, install the provided nanoSIM. If you have an Android phone with a pre-installed nanoSIM or an iPhone 13 or later with an electronic nanoSIM or eSIM, you can skip this step.

3. If you have a new Xfinity Mobile phone, unbox it, ensuring the device is turned off. If you’re bringing your own device (BYOD), open the package containing the Xfinity Mobile nanoSIM card.

4. Visit, log in or create an account, and select the phone you want to activate.

5. Choose whether to keep your existing phone number or get a new one.

6. Click the activate button, and your phone should be ready in about ten minutes.

7. Enter details about your device, including the IMEI number.

8. Provide the account number and PIN from your previous carrier when prompted, using the information gathered earlier.

9. Watch for a confirmation email if you opted for a new number.

10. If required, insert the Xfinity nanoSIM card or activate the line with your eSIM.

Once you complete the Xfinity Mobile activation, your phone will be ready for internet access, calls, and messaging.

How Do I Activate a New Line With eSIM?

If you’re transitioning from a nanoSIM device to an eSIM device, avoid inserting the old nanoSIM card into the new device, as this may lead to activation issues.

There are three methods to activate a new eSIM line:

1. URL (Website Address):

  • Navigate to your settings screen.
  • Select “Cellular.”
  • Opt for “Add Cellular Plan.”
  • Choose “Enter Details Manually” at the bottom of the screen.
  • Locate the SM-DP+Address field.
  • Enter “” into the SM-DP+Address field, ensuring the Activation Code and Confirmation Code fields remain empty.
  • Tap the “Next” button in the top right corner of the screen.

2. QR Code:

  • Navigate to your Settings screen.
  • Select “Cellular.”
  • Click on “Add Cellular Plan.”

Scan the QR code provided by Xfinity to activate your eSIM.

What Is an eSIM Quick Transfer?

An eSIM Quick Transfer streamlines the process for iPhone users to efficiently transfer a physical SIM or eSIM from one iPhone to another. Both devices must have iOS 16 or newer iOS software for this transfer to occur seamlessly.

Here’s a step-by-step guide:

1. Turn on your new phone and go to “Settings.”

2. Select “Cellular.”

3. Choose “Add Cellular Plan.”

For compatible iPhones, it’s also possible to convert a physical nanoSIM card to an eSIM in the “Settings” app. Navigate to “Cellular,” then “Convert to eSIM,” and the “Convert Cellular Plan” button should appear.

Ensure your eSIM is activated. After activation, your physical SIM card should be deactivated, allowing you to remove it from your iPhone and restart the device.

If you are not transferring between compatible iPhones, you’ll need to download a new eSIM card using the steps mentioned above.
