Learn more about Xfinity and Sonic

Xfinity and Sonic are top choices for internet service providers, as they both offer fast speeds 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.

Xfinity internet plans can reach gigabit download speeds of up to 10 Gbps on a fiber connection. Its cheapest cable internet-only plan is $30 per month. For high-speed, fiber internet, be prepared to shell out hundreds each month. That said, it offers more plan variety than Sonic, which only has three options – Fusion Fiber, Standard Fiber, and Basic Fiber.

With Sonic, you get speeds up to 1 Gbps, but pricing is much cheaper per month when it comes to gigabit plans. 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 vs Sonic: Best Deals

Internet Deals

Xfinity customers can get a monthly discount on select internet services for 24 months when bundling Xfinity mobile services. The provider also offers other appealing deals like free streaming service subscriptions and price guarantees without a term contract.

Sonic offers a free month of fiber internet service for new customers, though that’s about the only deal that you’ll find. Be on the lookout for new deals that may come up for both providers.

Xfinity Offers Better Bundles

Xfinity is a leading example of a provider that offers robust bundles for internet, TV, home security, and phone services. Customers who sign up for an Xfinity internet plan and bundle it with Xfinity Mobile can get a significant monthly discount with no term agreement. 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. It does, however, give customers access to a free VPN, which is a rare perk among internet providers.

You’ll Find Fewer Fees With Sonic

No Contract Options From Both Providers

Xfinity gives you the option to sign a contract to take advantage of current promos or go contract-free to avoid any commitments or fees. Sonic, on the other hand, doesn’t use contracts at all and offers month-to-month pricing.

Installation Could Cost You With Both Providers

Xfinity offers professional installation for a fee, semi-professional self-installation for a lower fee (installation with a tech support individual on the line), and self-installation that is completely free. However, with Sonic, you’ll get free self-installation unless you need fiber hardware, which will come with a fee.

No Data Cap With Sonic Internet

Xfinity’s cable internet plans come with a 1.2 TB data cap, but its fiber plan has unlimited data. Sonic doesn’t have any data caps on any of its internet plans.

Xfinity Wins in Customer Satisfaction

Since Sonic covers such a small swath of area, it’s hard to compare it to a national brand like Xfinity. That said, customers enjoy Sonic’s straightforward pricing and extremely quick speeds. However, Xfinity is more widely enjoyed as a top internet provider performer with high marks in national surveys, such as the American Customer Satisfaction Index (ACSI).
