....will I be able to continue as a Sonic customer or will I have to drop Sonic and sign up through AT&T? The AT&T website says I am already a customer when I give it my address.
You can still retain your current Sonic service and remain a Sonic customer. However, we are no longer reselling AT&T service, and all pre-existing Sonic customers on our resold AT&T services have been grandfathered in. This means that if you want to upgrade your service to a faster speed like AT&T Fiber (1,000mbps), we won't be able to do that. Unfortunately, you would need to switch to AT&T directly to get that service.
