If you have DSL don't expect anything from it.
It's a discontinued service and is not going to be maintained by AT&T if you move or the service gets damage in anyway it's not getting repaired or replaced.
Be prepared because sometime in 2022 they have been discussing about removing the satellite that provides the DSL service so you may lose the DSL service altogether.
They have no intention of providing a replacement for the broadband service they are removing in rural areas. They might put fiber in the city limits of your area if they decide it would be profitable for them to do so.
