Internet Buying Guides, Technology
Xfinity used to enforce a hard data cap of 1.2TB each month, but not anymore. It offers true unlimited data for every customer—so there’s no worry about overage fees or the speed slowdowns typically associated with unlimited data. Plus, Xfinity doesn’t require contracts, so it does not force you to keep internet service for 12+ months.
But is Xfinity right for you? Read on to find out why it’s an excellent value, whether you need unlimited data or not.

Xfinity ranks as the third fastest internet provider in our latest Internet Service Provider Review, falling closely behind home fiber providers T-Mobile Fiber and GFiber. In fact, the average speeds recorded with Xfinity have increased over the years, a reflection of the expansions and upgrades Xfinity has implemented since 2022.
Pick the best Xfinity plan for your home
Take a look at the plans you can get through Xfinity:
| Plan | Your starting price* | Download speed |
|---|---|---|
| 300 Mbps | $40/mo. for 5 yrs. | Up to 300Mbps |
| 500 Mbps | $45/mo. for 5 yrs. | Up to 500Mbps |
| 1 Gig | $50/mo. for 5 yrs. | Up to 1,000Mbps |
| 1.2 Gig | $100/mo. for 5 yrs. | Up to 1,200Mbps |
| 2 Gig | $100/mo. for 5 yrs. | Up to 2,000Mbps |
* Availability and speed may vary by location, and prices are subject to change. See disclaimers.
All five plans include an Xfinity Wi-Fi 7 gateway at no extra cost, giving you the fastest, most reliable Wi-Fi speeds to date.
Which Xfinity plan should you choose?
A quick way to determine which plan is right for you is to assume your most-used devices can stream 4K content (at 25Mbps each). Here’s how many simultaneous 4K streams each plan can handle:
- 300Mbps = 12 devices
- 500Mbps = 20 devices
- 1,000Mbps = 40 devices
- 1,200Mbps = 48 devices
- 2,000Mbps = 80 devices
Just keep in mind that the more people you have in a home, the more devices you’ll likely have accessing the internet simultaneously—plus all the passive devices you have installed inside and outdoors.
Our verdict: Five-year pricing adds great value
Avoid price hikes and long-term consistent pricing with a five-year price guarantee from Xfinity. Every plan has five-year pricing—the standard rate applies in the 61st month of service.
If you’re ready to lock in a five-year price guarantee, get equipment included with your internet plan, and score true unlimited data, sign up with Xfinity now!
