That makes it a marketing source, and it compares top plans rather than entry-level ones. Competitor prices vary by address and change often, so confirm them on each provider's site.

How to check your address
City names don't tell you much, because fiber gets built one block at a time. The way to know is to enter your street address on Sonic's availability tool, which is what the button on this page opens.
If Sonic is still building in your area, you can pre-order: Sonic says that locks in the current deal, gives you first dibs on install appointments, and you pay nothing until installation is complete.
