Let’s grab our calculators and dig into the details to see why these three AT&T internet plans stand out when it comes to price. Quick note: The fact that the Internet 100 plan is a fiber-DSL hybrid also means it’s limited to areas where AT&T has built out its fiber network. So you may not be able to get it in your home. The best way to find out if you can get this plan is to enter your address on the AT&T site—or try out our easy zip checker tool. Turns out it’s a good price for the speed you get—for the most part. Let’s take a look at each of AT&T’s internet plans and the price per Mbps for each one: Counting on 60 cents per Mbps for Internet Up to 75 Mbps is correct only if you can get the max speed of 75 Mbps. If speeds in your area are slower than 75 Mbps, your value goes down. (This is another instance where we’d recommend looking to see if there’s a local ISP or another rural internet provider with a better price.)
