Xfinity and Sonic are top choices for internet service providers as they both offer fast speeds, unlimited data, and affordable monthly pricing. Xfinity is the largest cable provider in the U.S., offering cable and fiber connections to residential customers. Sonic primarily offers fiber internet but has gigabit speeds without the expensive price tag. We cover key similarities and differences between the two providers below.

Xfinity internet plans can reach gigabit download speeds of up to 3 Gbps on a cable or fiber connection. Its cheapest, cable internet-only plan is $35 per month, but if you want fiber internet, keep in mind that it costs a hefty $299.95 per month. That said, it offers more plan variety than Sonic, which has three options: Fusion Fiber, Standard Fiber, and Basic Fiber.

With Sonic, you get speeds up to 10 Gbps but pricing is much cheaper at per month. What you won’t get are other connection options, as you’re stuck with only one fiber internet plan. It’s also only available in certain areas of California, so availability is extremely limited.

Xfinity excels in its coverage across the U.S. and also has an award-winning customer service department. Aside from fast internet plans, Xfinity offers robust packages that include internet, TV, and phone services. The caveats with its services are that you need to sign a contract to take advantage of most deals, and its fiber plan is significantly more expensive than what other providers offer.

While Sonic also offers gigabit download speeds on a fiber connection, it’s only available in California. On the flip side, Sonic’s one and only plan is very affordable and standard installation is included. If you live in one of its coverage areas, you might want to take advantage of its fiber speeds for the cheap price point.

Each package that includes TV service has hundreds of channels and optional contracts.

Sonic does offer a bundle that includes internet and phone services, but other than that, it doesn’t have TV service.

Xfinity vs. Sonic: Extra Fees and Contracts

Xfinity gives you the option to sign a contract to take advantage of current promos or go contract-free so you don’t have to worry about early termination fees. Sonic, however, does require a one-year service agreement, and if you end it prematurely, you’ll have to pay an ETF.
