Guide to High Speed Internet

Check coverage

Most internet companies are limited in geographic scope and even more so if you’re looking for fiber-option plans. In most cases, it’s easy to find your available options by simply typing in your zip code on a carrier’s website.

Decide how much speed you need

When evaluating plan speeds, think about how frequently you stream and upload content online. However, since speeds can vary based on the amount of traffic (particularly during peak streaming hours), consider the service provider’s reputation as well. While a service provider may provide one speed in one area, its speeds may be different in another. 

Study pricing

Most internet carriers come with additional fees on top of your monthly rate, but that doesn’t mean it’s all the same. Compare your local options and compare prices for areas like taxes, equipment, rental fees, and installation fees. Also make sure to check the expiration date on any promotional offers to ensure your savings are maximized. 

Consider bundling

Many carriers offer an attractive discount if you bundle internet with other available services, such as phone or cable television. Verizon, for example, offers bundling discounts when you pair internet with cell phone service, while you can save with AT&T when you sign up for internet and DIRECTV.
