Xfinity Mobile Promo Codes + Cashback in November 2026

New customers activate for $0 right now because Xfinity waives its standard $25-per-line activation fee on a first order. This deal is current and can change over time, so confirm it still applies when you sign up.

Once you're past that first setup, Xfinity charges a one-time $25 fee every time you add a phone or tablet line down the road. It's a small charge on its own, but it adds up when you bring on lines one at a time.

The smart move is to set up every line you expect to need during your first order while the waiver is active. A family or household that needs three or four lines can add them all at once so the $0 waiver covers the whole group. Come back a month later to add another line, and you'll pay the $25 fee for that one, so it pays to plan your lines up front.

Xfinity Mobile ships every device free with two-business-day delivery and no minimum order. So getting a phone, tablet, or smartwatch never costs you extra. That's a real edge when you're starting a new line, since some carriers still charge a setup or shipping fee just to mail you the device. You'll get a tracking email as soon as your order goes out.

Bringing your own phone? A physical SIM card ships free in a standard envelope and usually arrives within five business days, no signature required. A phone that supports eSIM skips shipping altogether and activates instantly, which saves you both the wait and a trip anywhere.

One thing to get right before you order. Everything locks in once it ships. Devices go straight to your Xfinity Internet service address for security, and you can't change that address or cancel the order afterwards. So double-check your details up front. And should you end up not wanting the device, don't refuse the package at your door, because that only slows your return down. Accept it and start a standard return through your Xfinity account instead.

Refer a friend to Xfinity Mobile and you both get rewarded. As a current customer, you can earn up to $50 for every friend who signs up, up to $500 total each calendar year. That works out to about ten successful referrals to max out your reward. That makes this offer one of the easiest ways for a long-time member to keep money coming back.

Your friend wins too. They can earn up to $50 for signing up for new Xfinity Internet, plus another $50 for each new mobile line they add, up to five lines. Just know that only brand-new Xfinity Mobile customers qualify, and their services have to stay active for 90 days before either of you gets paid.

So the next time someone you know is shopping around or frustrated with their current carrier, send them your referral link. Once they're set up and past that 90-day mark, you both come out ahead.

Yes. Verified military members with Xfinity Internet get one unlimited Xfinity Mobile line free for two years, one of the biggest savings you can score on your mobile service. The discount lands within one to two billing cycles after you add the line, so don't panic when it isn't there right away.

To keep the free line, you'll need to stay an active Xfinity Internet subscriber. And a move somewhere Xfinity Internet isn't offered means Xfinity waives the usual mobile-only access fee, so your line stays penalty-free.

The offer covers active-duty and reserve members, veterans and retirees, Gold Star families, and household spouses or family. To claim it, verify your status with a valid military ID and email, and approval is usually instant. Adding extra lines later starts at just $30 a month.
