Xfinity vs. T-Mobile

We recommend installing your Xfinity Internet first. Start by selecting your Xfinity Internet plan. Once you’re online, call T-Mobile at 800-937-8997 to close your home internet account. For mobile, the process is even simpler: once we move (or “port”) your number to Xfinity, your old T-Mobile line will automatically close. We handle the number transfer process with your old carrier behind the scenes, ensuring a smooth switch so you don’t have to sit on the phone for hours waiting for T-Mobile to cancel your account. Tablets and smartwatches will need to be manually canceled. However, you can connect up to 10 cellular tablets and watches for $35/mo. Included with our latest plans. Excludes fees and taxes.

Switching gives you a double win for your budget. You can save over $2,100 over five years on your home internet alone compared to T-Mobile 5G Home Internet. On top of that, families can cut their mobile bill in half just by switching their phone service to Xfinity. While T-Mobile mobile plans start at $55/mo for a single line, new Xfinity Mobile members can get an unlimited Mobile Select line for free for their first year, then just $30/mo after that.

• 5-Year Price Guarantee

Xfinity provides more built-in value than T-Mobile. While T-Mobile typically charges an extra monthly fee for device protection, Xfinity includes Xfinity Mobile Care (device protection) for life at no extra cost on our Mobile Plus plan. Additionally, both of our newest plans—Mobile Select and Mobile Plus—now include unlimited talk, text, and data in 215+ destinations as a standard feature, whereas T-Mobile gates their best travel perks behind their most expensive plan tiers.

You can be up and running in minutes. Our same-day, self-install WiFi kits are designed for a quick and easy nearly instant setup, matching the convenience of 5G while providing a much more stable, high-speed connection. Prefer a hands-off approach? You can easily schedule a professional installation with an expert Xfinity technician to ensure your home network is perfectly optimized from day one.

T-Mobile 5G Home Internet relies on cellular signals through the air, which can be slowed down by bad weather, trees, or even heavy local tower congestion during peak evening hours. Xfinity uses a fiber-powered, wired connection to your home that delivers consistent, multi-gigabit speeds unaffected by the weather or how many of your neighbors are using their phones at the same time.

Xfinity provides a dedicated wired connection that offers more consistent performance than cellular-based signals.

 

• Speed: Xfinity delivers multi-gigabit speeds that are consistently fast and built for your home WiFI, whereas T-Mobile’s 5G Home Internet signal runs off a cell tower and can fluctuate or slow down during peak hours or bad weather.

• Network Priority: We prioritize your dedicated home connection. T-Mobile prioritizes the cell phones on its network before its 5G Home Internet customers, meaning your home internet speeds can take a hit whenever their cellular network gets crowded.

• Data: Xfinity features no data caps on postpaid high-speed plans. While T-Mobile claims to be unlimited, their fine print admits they will further reduce your speeds if you use more than 1.2TB in a month. With Xfinity, you get truly unlimited data without those hidden usage penalties.

• Reliability: Our fiber-powered, wired connection provides lower lag (latency) for gaming and video calls compared to T-Mobile’s air-based 5G Home Internet.

• Streaming & Live TV: Xfinity supports seamless live TV and 4K streaming across all your devices. T-Mobile’s 5G Home Internet is actually incompatible with certain live TV services, and their terms state that video apps must be left at default resolutions—meaning you may not get the high-quality HD or 4K video you're paying for.

• Pricing & Contracts: Xfinity provides a 5-Year Price Guarantee on internet plans, and lets you cut your total mobile bill in half compared to T-Mobile.

No. We believe in providing value through our performance rather than a signature. You’ll enjoy the freedom of no annual contracts, giving you the flexibility to change your plan or even cancel anytime without a penalty. We provide long-term budget certainty through our price guarantees, not through paperwork hurdles.

While both offer a 5-year guarantee, Xfinity locks in the price of a superior, wired product. T-Mobile locks in a cellular signal that can fluctuate or slow down during poor weather events and peak times. However, Xfinity’s 5-Year Price Guarantee gives you budget certainty for fiber-powered internet that is consistently fast and reliable. By pairing this guaranteed rate with mobile savings that cut your bill in half, you’re locking in better performance for a much lower total monthly cost.

No. Xfinity features no data caps on our most popular high-speed plans (300 Mbps and faster). While competitors like T-Mobile claim to offer unlimited data, their terms state they will further reduce your speeds if your household uses more than 1.2TB in a month. Xfinity gives you truly unlimited data, so your family can stream, download, and game heavily without worrying about hidden usage penalties or overage fees.
