What independent data reveals about our performance
Most mobile services force you to choose: trade-offs between coverage, reliability, speed, and price, making you feel like something's missing. But not with Xfinity.
Xfinity Mobile combines the nation’s best cellular network1 with millions of secure Xfinity WiFi hotspots to give customers better coverage, stronger reliability, faster everyday speeds, and great overall value, without any of the trade-offs.
In short: Xfinity Mobile delivers the best mobile experience by seamlessly integrating the nation's top-ranked cellular network with 23 million WiFi hotspots, to provide unmatched coverage, reliability, and speed wherever you are.1
Xfinity Mobile Coverage and Network Performance
Xfinity Mobile runs on America's most widely used cellular network, ranked by Ookla’s RootMetrics as the best performing and most reliable network in 2025.1 This means strong coverage across cities, suburbs, highways, and rural areas. You can stay connected whether you're commuting, traveling, or running errands.
The Largest Secure WiFi Network
Xfinity Mobile provides the best mobile coverage wherever life takes you, based on the best cellular coverage2 plus our network of millions of secure WiFi hotspots nationwide. Your phone connects automatically with your Xfinity Mobile subscription: no passwords, no extra steps.
We provide access to 23 million secure WiFi hotspots nationwide. This network fills in gaps where cellular signals can be weaker, ensuring that you stay connected, no matter where you are.
Better Coverage Indoors (Where Life Happens)
Nearly 90% of cell phone usage happens on WiFi: at home, at work, in schools, stores, and apartments.
Cellular signals often struggle to get through walls and buildings. In fact, some of the big cellular companies have coverage gaps indoors about one-quarter of the time3. WiFi doesn't have that problem.
By leveraging our WiFi network, Xfinity Mobile helps you stay connected in places where cellular-only services may slow down or drop.
For you, that means fewer dead zones, fewer missed messages, better calling capabilities, and better service where you actually spend your time.
Together, cellular + WiFi create a larger real-world coverage footprint than cellular alone.
How Xfinity Mobile CombinesWiFiand Cellular for Reliability
Network That Adapts
Xfinity Mobile doesn't rely on just one path to keep you connected: On the Xfinity Mobile network, your phone can use your 5G or LTE service, or switch to WiFi. Your device automatically chooses the best option available at that moment.
Less Congestion, Fewer Drop-Offs
Cellular networks can get crowded, especially in busy places like stadiums, malls, or apartment buildings.
When WiFi is available, Xfinity Mobile can move traffic off crowded cellular networks, Automatically shifting your connection to the better-performing network helps keep connections stable and reliable.
This means we can provide the best possible connection automatically at home, on a call, and even while in transit. Only Xfinity can keep you connected reliably and dynamically through our millions of WiFi hotspots, something the Big 3 providers can't do.
For you, this means fewer dropped calls, smoother streaming, and more consistent service throughout the day.
Xfinity Mobile’s WiFi and cellular networks work better together to keep you connected, even when conditions change.
Speed: Fast Where It Matters Most
Fast Cellular Speeds
Xfinity Mobile delivers top-tier 5G speeds on cellular networks, giving you fast downloads, smooth video, and responsive apps on the go.
WiFi PowerBoost: Upgrade to Gig-Speeds
When connected to Xfinity WiFi at home or on the go, our WiFi PowerBoost feature can deliver ultra-fast speeds: up to 1 Gig on compatible WiFi connections.4

Technical Corner (Network Switching and 6G Made Simple)
How It Works
Your phone is always checking which connection is best: If cellular is strong, it uses cellular. If secure Xfinity WiFi is faster or more reliable, it switches to WiFi. This happens automatically, in the background.
Why This Matters for the Future
The mobile industry is moving toward network convergence (using multiple connection types together instead of relying on one). This is best exemplified through the pursuit of 6G, where cellular and WiFi networks will work together to optimize for the best possible connection.
As we look ahead to future technologies like 6G, networks that already combine cellular and WiFi will be best prepared. Xfinity Mobile's approach is built for this future today.
Xfinity Mobile will leverage our WiFi footprint to optimally direct traffic for our customers between WiFi and cellular. Through our networks, we have the scale to deliver for a 6G future, both in-home and out of home.
Great Value Without Compromise
By using WiFi whenever possible, Xfinity Mobile customers see better performance, cellular data goes further, and networks stay less congested.
This leads to a more consistent, higher-quality experience when compared to other providers, so you never have to worry about choosing between performance and price.
