Spectrum Internet is the best unlimited internet with no data caps. It’s also affordable, widely available to millions of customers across the country, and sufficiently fast without going overboard.
It used to be the case that internet providers levied "data caps" on customers, limiting the amount of data you can consume on your internet plan every month. Data caps are still around (especially with satellite internet and mobile plans) but a lot of internet providers nowadays offer unlimited data with no caps whatsoever, or at least very generous caps.
If you plan to consume tons of data on your internet plan with 4K movie marathons, large video game updates, or extensive Zoom calls, I also recommend T-Mobile 5G Home Internet, Google Fiber, AT&T Fiber, and Astound Broadband. There are several other great providers that I give an honorable mention farther down below as well.
Whatever you go with, one thing’s for certain: It’s time to stop bumping up against that dreaded data limit.
