Xfinity Mobile plans

Xfinity Mobile uses Verizon’s cellular network, so you’ll get standard features like nationwide phone coverage and 5G support with any Xfinity Mobile plan. Other benefits include contract-free pricing and access to Xfinity’s hotspot network.

Xfinity Mobile’s By the Gig plan is best suited for families with basic cell phone needs. Along with a $15 monthly fee per phone line, you’ll pay for a mobile data pool that’s shared among your family.

Unlike providers like Spectrum Mobile, Xfinity Mobile’s shared data packages make By the Gig surprisingly competitive. By the Gig’s 3 GB and 10 GB data pools have affordable per-gigabyte pricing (Xfinity typically charges $15 per GB), and the data plans are a great fit if certain family members want more data but can’t afford an Unlimited line.

Xfinity Mobile’s Unlimited plan offers a 20 GB data cap per line before your speeds get throttled (1.5 Mbps for downloads, 750 Kbps for uploads).

20 GB isn’t a bad cap by carrier standards, although it’s on the lower end compared to the competition. Spectrum Mobile offers a 30 GB plan, while Verizon includes a 50 GB cap. Most people will be fine with Xfinity Mobile’s cap, but you might run into problems if you’re frequently watching TV episodes or downloading games on mobile data.

Pro tip: Depending on where you live, Xfinity may offer a $30 bundle that includes a 300 Mbps internet plan, Xfinity Mobile, and an Xfinity Flex. Check out our Xfinity deals guide to see if you qualify for the promotion.

The Unlimited plan’s staggered per-line pricing is one of its biggest advantages, as you’ll get a larger discount for every line you add to your account. For instance, you’ll pay $40 per line with two lines and only $24 per line with 10 phone lines.

By comparison, Spectrum Mobile’s unlimited plan comes with only one discount ($29.99 per line with more than two lines). Xfinity Mobile will offer the best savings if you’re getting service for more than five people.

Xfinity Mobile fees

Xfinity (of all providers!) has shockingly few fees attached to its Xfinity Mobile service—you won’t even have to pay any activation or access fees. But if you want to add a smartwatch or tablet to your mobile data plan, you’ll need to pay an additional $10 per month. (If anything needs what-you-see-is-what-you-get pricing more than internet plans, it’s smartphone plans.)

Because Xfinity Mobile requires Xfinity internet, you’ll get hit with a continuing $25 monthly fee if you leave Xfinity but want to keep Xfinity Mobile. But Xfinity Mobile’s no-contract setup means you won’t have early termination fees if you cancel service early.

We’re similarly unenthused about Xfinity Mobile’s HD Pass. If you have a 4G device on an Unlimited plan, you can pay an extra $20 per month to stream videos in high definition. But if you have a 5G-capable smartphone, you’ll be able to watch videos in high definition without needing to pay for an HD Pass. Skip HD Pass, and don’t give it a second thought.

What to look for

For families shopping for service, Xfinity and Xfinity Mobile plans have more overlap than you’d expect. From data charges to Disney+, here’s everything else you’ll need to know about Xfinity Mobile’s plans.

Data usage

To figure out your family’s data needs, think about their smartphone habits. Are you mainly using your phone for phone calls and texts? Are your kids regularly streaming podcasts and listening to Spotify?

If your family simply needs phone service, we’d recommend a 1 GB or 3 GB By the Gig plan. But if more than a few family members are regularly using their phones for Netflix shows and Reddit, consider getting them Unlimited plans. Xfinity Mobile allows you to mix and match, so your account can have Unlimited and By the Gig plans to meet every family member’s smartphone needs. .

Xfinity Mobile deals

Xfinity Mobile is great if you’re an Xfinity internet customer interested in affordable smartphone plans, but don’t expect much beyond that. Plans from carriers like AT&T and Verizon are pricier than Xfinity Mobile, but they also add promos like free HBO Max subscriptions and bundled international data access.

By comparison, Xfinity Mobile’s best deals start and end with its plans. For instance, you’ll have to buy a daily pass ($5 or $10) or pay for data by the megabyte (around $0.05 to $0.25 depending on country) if you’re traveling overseas with Xfinity Mobile.

It’s hard to beat Xfinity Mobile’s low prices, but if you’re already subscribed to other streaming services or regularly travel overseas, look at the bonus add-ons you’ll get from competing providers to ensure you get the best deal.

While features like its 20 GB data cap are nothing to write home about, Xfinity internet customers who want to save on their smartphone bill will find a lot to like with Xfinity Mobile.
