*Prices shown per line, 1-line rate, with active Xfinity internet subscription. Multi-line: 2nd line at reduced rate depending on plan. After premium data allowance is reached, data continues at standard speeds. No contract on wireless service — cancelling wireless does not affect your Xfinity internet. All prices before taxes and fees.
By the Gig is best for light data users: At $15/GB, if you use 2 GB in a month you pay $30 — cheaper than the $40 Unlimited plan. If you use 3 GB you pay $45 — more expensive than Unlimited. The break-even is around 2.5 GB/mo. If you consistently use under 2 GB (mostly on WiFi), By the Gig saves you money every month.
| Monthly Data Used | By the Gig Cost | Unlimited Cost | Better Option |
|---|---|---|---|
| Under 1 GB | $15 | $40 | By the Gig — save $25 |
| 1–2 GB | $15–$30 | $40 | By the Gig — save $10–$25 |
| 2–3 GB | $30–$45 | $40 | Roughly equal — go Unlimited |
| 3 GB+ | $45+ | $40 | Unlimited — save $5+/GB over |
*Data is shared across By the Gig lines on the same Xfinity account. Xfinity WiFi offload does not count toward your GB usage — the more Xfinity hotspots near you, the less cellular data you consume. Customers in dense Xfinity coverage areas often find By the Gig very economical.

Who It’s For
Is Xfinity Mobile Right for You?
✅ Great fit if you…
Already have Xfinity internet and are paying a major carrier $60–$90/mo per line. You live or work near Xfinity WiFi hotspots (very common in the Northeast, Pacific Coast, and Sun Belt cities). You want Verizon’s network quality without Verizon’s pricing. You’re a family with multiple lines to save on multi-line pricing.
Potential savings: $25–$50/mo per line
⚠️ Consider alternatives if you…
Don’t have Xfinity internet — Xfinity Mobile is not available without it. Need strong rural coverage (T-Mobile-based plans like Tello or Mint cover more rural areas). Want the absolute cheapest option (Tello at $29/mo unlimited is cheaper). Need to switch internet providers and don’t want to be locked into Xfinity’s ecosystem.
Alternative: Visible ($25/mo on Verizon, no internet req.)
FAQ
Xfinity Mobile — Common Questions
Do I need Xfinity internet to get Xfinity Mobile?▾
Yes — Xfinity Mobile requires an active Xfinity internet subscription. It is not available as a standalone wireless service.If you cancel your Xfinity internet service, your Xfinity Mobile service will also be cancelled or you’ll need to pay an early termination fee on the wireless side. However, you can cancel your Xfinity Mobile wireless at any time without affecting your Xfinity internet plan. The requirement works one way — internet enables wireless, but wireless doesn’t require you to keep wireless to keep internet. Call (978) 723-5746 if you’re considering switching your internet provider and want to understand what happens to your wireless service.
What network does Xfinity Mobile use?▾
Xfinity Mobile runs on Verizon’s 4G LTE and 5G nationwide network, supplemented by Xfinity’s own WiFi hotspot network.When you’re near an Xfinity WiFi hotspot, your phone automatically connects and data usage counts against WiFi rather than your cellular plan. Xfinity has millions of hotspots in public places, apartment buildings, and businesses — particularly dense in the Northeast, California, Florida, and other major Xfinity markets. The Verizon network handles all cellular coverage everywhere else. This dual-network approach often means Xfinity Mobile customers use less cellular data than customers on pure cellular plans.
Can I bring my existing phone to Xfinity Mobile?▾
Yes — Xfinity Mobile supports BYOP for unlocked phones compatible with Verizon’s network. Most modern iPhones and Android phones are compatible.iPhones (iPhone 8 and newer) and most recent Android phones support Verizon’s network and can be used with Xfinity Mobile. If your current phone is locked to T-Mobile, it may still be compatible since most T-Mobile phones support Verizon bands. Verizon phones are natively compatible. AT&T phones should be checked for band compatibility. Check xfinity.com/mobile/byop to enter your IMEI and verify compatibility. Call (978) 723-5746 for compatibility help.
Is the By the Gig plan worth it or should I go Unlimited?▾
By the Gig ($15/GB) is worth it if you consistently use under 2.5 GB of cellular data per month. Above that, Unlimited at $40/mo becomes cheaper.Check your current carrier bill for your monthly data usage — most carrier apps show a 6-month usage history. If you average 1–2 GB of cellular data monthly (common for people on WiFi most of the day), By the Gig saves $10–$25/mo vs. Unlimited. Xfinity WiFi hotspot offload reduces your cellular usage further — customers near hotspots often find By the Gig significantly cheaper than expected. Start with By the Gig; you can switch to Unlimited any month if usage increases.
How does Xfinity Mobile compare to Spectrum Mobile?▾
Both are cable-company wireless plans on Verizon’s network. Spectrum Mobile ($29.99/mo unlimited) is cheaper; Xfinity Mobile ($40/mo unlimited) has a stronger WiFi offload network and more plan tiers.Key differences: Spectrum Mobile requires Spectrum internet (not Xfinity). Xfinity Mobile requires Xfinity internet. If you have Xfinity, Xfinity Mobile is your cable-bundle option. If you have Spectrum, Spectrum Mobile is your option. The underlying Verizon network is the same for both. Spectrum Mobile is $10/mo cheaper on unlimited. Xfinity Mobile’s extensive WiFi hotspot network can reduce actual cellular data usage. For eligible customers, Spectrum Mobile has the lower sticker price. Call (978) 723-5746 to compare based on your current internet provider.
Does Xfinity Mobile have a family plan discount?▾
Yes — Xfinity Mobile offers reduced per-line pricing for multiple lines on the same account. The second line on Unlimited plans is typically discounted.Pricing for multi-line families: the exact per-line rates for 2–5 lines vary and are updated periodically.

Lines can mix plan types — one person on By the Gig, another on Unlimited. Call (978) 723-5746 for current multi-line rates and to calculate your specific family savings.

Physical SIM cards are also available at Xfinity stores and can be ordered online. Call (978) 723-5746 to activate eSIM or get a physical SIM shipped.
Can I get a new phone through Xfinity Mobile?▾
Yes — Xfinity Mobile sells a full range of smartphones including iPhone, Samsung Galaxy, Google Pixel, and Motorola devices, with 0% financing over 24 months available.Xfinity Mobile periodically offers trade-in promotions for new customers — you trade in your old phone and receive a credit toward a new device. These promotions can be significant (up to $800 toward a new iPhone with qualifying trade-in). Unlike carrier lock-in, Xfinity Mobile’s financing is tied to the device installment plan, not a service contract — you can keep financing your phone while switching wireless plans. Call (978) 723-5746 for current device promotions and trade-in values.
What happens to Xfinity Mobile if I cancel Xfinity internet?▾
If you cancel your Xfinity internet subscription, your Xfinity Mobile service will be terminated — or you’ll have 30 days to port your number out to another carrier.Xfinity gives customers a grace period when internet service ends. During this window, you can port your phone number to any other carrier (Visible, Spectrum Mobile, a major carrier) and keep your same number. If you’re considering switching internet providers, port your number first, then cancel internet. This avoids losing your phone number. Call (978) 723-5746 for help planning the transition.
Does Xfinity Mobile work in other countries?▾
Yes — Xfinity Mobile’s Unlimited Premium plan includes international roaming in select countries. Standard plans offer international calling and data add-ons at per-day or per-use rates.For occasional international travel (1–2 trips per year), Xfinity Mobile’s international add-ons are typically sufficient. For frequent international travelers who need seamless data roaming, AT&T Premium (200+ countries) or T-Mobile Go5G Plus (215+ countries with free texting and basic data) are better options. Call (978) 723-5746 to discuss international options and whether the Premium plan makes sense for your travel schedule.
