Activating a new line with eSIM using the Xfinity Mobile website is also an option. Go to xfinitymobile.com/activate, log in or create an account, and select Devices. Choose the phone you'd like to activate and pick between Keep your existing number or I want a new number.
If you're switching devices on your already-existing Xfinity Mobile line, you can only do this from the website. To do so, go to xfinitymobile.com/activate, log in or create an account, and select the phone you'd like to activate.
To transfer your current phone number, you'll need your previous account number and PIN. You can find this information on one of your past bills or by giving your previous carrier a call for assistance. If you want a new number, Xfinity Mobile will automatically assign you one once the phone is activated.
The activation process typically takes about 10 minutes, and you'll receive a confirmation email when it's complete. If you're using eSIM, the eSIM should download automatically. If it doesn't, look for any notifications and follow the prompts to complete the process.
Here are the general steps to activate your Xfinity Mobile phone:
- Go to xfinitymobile.com/activate or download the Xfinity app.
- Log in or create an account.
- Select the phone you'd like to activate.
- Pick between Keep your existing number or I want a new number.
- Follow the prompts to complete the activation process.

Preparation and Planning
Before you start the activation process, it's essential to check a few things to prevent delays later.
First, confirm that you're eligible for Xfinity Mobile service, which is available to Xfinity Internet customers. If you cancel your Xfinity Internet/TV/Voice later, a standalone mobile fee may apply unless you keep an eligible service.
To ensure a smooth setup, run your IMEI on the official BYOD tool to check compatibility and determine whether to use eSIM or a physical SIM. You can find your IMEI by dialing *#06#.
Also, check if your phone is unlocked, especially if you're bringing an iPhone. Go to Settings > General > About > Carrier Lock, and look for "No SIM restrictions." If you're an Android owner, confirm with your previous carrier that your phone is unlocked.
Here's a quick checklist to get you started:
- Service eligibility: Check if you're an Xfinity Internet customer.
- Compatibility: Run your IMEI on the official BYOD tool.
- Unlocked phone: Check for "No SIM restrictions" on your iPhone or confirm with your previous carrier.
- Number transfer info (optional): Gather the account number and transfer PIN from your old carrier, if needed.
- Battery & Wi-Fi: Charge above 50% and connect to Wi-Fi for a smoother eSIM download.
Before You Start: Checklist
Before you start switching to Xfinity Mobile, take a few minutes to do some quick checks to prevent delays later. It's like doing a pre-flight check before taking off - it ensures a smoother ride.

If you want to keep your old number, you'll need the account number and transfer PIN from your old carrier.
Before setting up your eSIM, make sure your battery is charged above 50% and connect to Wi-Fi. This will ensure a smoother download and installation process.

Xfinity Mobile also offers a By the Gig Plan, which is perfect for light users who don't need a lot of data. This plan is great for those who only use their phone occasionally.
One of the best things about Xfinity Mobile is that their plans have no line access fees, which means you won't be charged extra for each line on your account. This can save you money in the long run.
Their plans are also contract-free, so you're not locked in for any set length of time. This gives you the freedom to switch plans or carriers whenever you want.
