Xfinity Mobile works as a Mobile Virtual Network Operator (MVNO) that uses Verizon's 5G and 4G LTE networks for cellular coverage, combined with millions of secure Xfinity WiFi hotspots for automatic data offloading. The service is exclusively available to residential Xfinity Internet customers, who can choose between two unlimited plans with no line access fees and no term contracts.
How does Xfinity mobile work?
Xfinity Mobile operates as an MVNO, meaning it leases network capacity from Verizon rather than building its own cell towers. This gives customers access to Verizon's nationwide 5G and 4G LTE coverage. A key differentiator is the automatic use of millions of Xfinity WiFi hotspots, when your phone detects a hotspot, it connects automatically to save cellular data. This hybrid approach reduces strain on the cellular network and helps you manage data usage without thinking about it. All plan management, including adjusting your Xfinity Mobile services and settings, is handled through the Xfinity app or website.
Xfinity Mobile eligibility and what you need to sign up
To sign up, you must have a residential post-pay Xfinity Internet account. You cannot add Xfinity Mobile to a business internet plan or a prepaid internet account. Integration with Xfinity Home internet service allows for bundled discounts and streamlined billing. Before starting, check device compatibility on the Xfinity Mobile website, most modern unlocked Apple, Samsung, Google, and Motorola phones are supported. For activation, you will need your Xfinity ID and password. If you are transferring your phone number, you will also need your previous carrier's account number and PIN. You can add up to five lines to your account on the Unlimited plan.
Xfinity Mobile plans: Mobile Select and Mobile Plus
Xfinity Mobile currently offers two unlimited plans, both with unlimited talk and text. The discontinued By the Gig option is no longer available for new customers who joined after April 22, 2026, though existing customers on that plan can keep it. The By the Gig plan starts at $15 per GB.
Mobile Select includes 50 GB of premium data. After that, speeds may be slowed during network congestion. It includes unlimited mobile hotspot data, though speeds may be reduced after a certain usage threshold or during congestion. Video streams in high definition.
Mobile Plus offers unlimited premium data, your speeds are never deprioritized or slowed due to congestion. It includes 15 GB of mobile hotspot usage at high speeds, with unlimited hotspot data at reduced speeds after that. Video streaming supports up to 4K resolution.
Xfinity Mobile pricing, fees, and promotions
There are no phone line access fees on either plan. You pay only the plan cost per line, plus taxes, regulatory recovery fees, and other charges that are extra and subject to change. Promotional phone deals typically involve 24-month bill credits, if you cancel service early, the remaining credits are forfeited. There are no term contracts, so you are not locked into a long-term agreement beyond any device financing.
Xfinity Mobile coverage and network performance
Coverage is provided by Verizon's 5G and 4G LTE networks. On the Mobile Select plan, your data may be deprioritized during congestion after you use 50 GB of premium data, meaning other Verizon customers could get faster speeds in crowded areas. Mobile Plus avoids this entirely with unlimited premium data. In addition to cellular coverage, your phone automatically connects to millions of Xfinity WiFi hotspots nationwide, which can save cellular data and improve speeds in indoor locations like cafes, airports, and shopping centers. The coverage map tool on the Xfinity Mobile website allows you to check estimated network coverage by entering your address or ZIP code.
Xfinity Mobile international features
Both Mobile Select and Mobile Plus include international roaming at no extra cost. Xfinity Mobile provides free international calling and texting to over 200 countries. You get free calling and texting to over 215 destinations, and unlimited data for international travel in those same destinations without needing a separate pass. This makes the service particularly useful if you travel abroad or frequently call family overseas.
