Frequently asked questions

How do I add a line to my Xfinity Mobile account?

Get set up in minutes. Adding a line is a simple three-step process you can do entirely from the Xfinity app. Just sign in, head to Manage Mobile Service, and select the Devices tab. From there, you can choose to bring your own phone or shop for a brand-new device. We’ll show you all eligible savings and promotions before you check out.

Can I get a deal on a new device when adding a line?

Yes. Adding a line is one of the best times to upgrade your tech. We frequently offer exclusive promotions and discounts on the latest 5G smartphones, tablets, and smartwatches from top brands like Apple, Samsung, and Google. You can explore our latest mobile deals to find the perfect new device for your new line. You can even trade in an old phone for additional credit to make your device upgrade even more affordable.

What plans are available when I add a new line?

Xfinity Mobile gives you the flexibility to mix and match plans on a single account. For each new line, you can choose between our Mobile Select plan for everyday value or our Mobile Plus plan for premium features, like included device protection. You can even move a line between these two options at any time if your data needs change, ensuring you’re never locked into a plan that doesn't fit.

Can I bring my own phone when adding a new line?

Yes. Bringing your current device is the fastest way to expand your plan. Most modern, unlocked phones are compatible and can be set up via eSIM in minutes.  Learn more about bringing your own device.

How many lines can I add to my Xfinity Mobile account?

Depending on your account eligibility, you can have up to 22 total lines on your Xfinity Mobile account. This includes up to 10 tablet and smartwatch lines and up to 12 phone lines.

Does Xfinity Mobile have special plans for tablets and watches?

Yes. You can add your favorite cellular devices for a low monthly fee — just $10/mo per smartwatch and $20/mo per tablet. Households with multiple devices can save big with our All-In Tablet & Watch Plan, included with our latest plans. Connect up to 10 tablets and watches for $35/mo, excluding taxes and fees.

Even better, if you choose the Mobile Plus plan, all watches and tablets connected to your account will be covered with Xfinity Mobile Care Plus device protection at no extra cost. Learn more about our tablet plans and smartwatch plans.

Can I trade in my old phone when adding a new line?
