Blackouts are specific to your current location, so if your location changes, your blackout restrictions for live, locally televised games will also change. Your location is determined by the IP address or location services (if turned on).
Some ESPN network content will only be available to customers of a participating TV provider. For example, certain NBA games, College Football Playoff games, and select NFL games will not included in your ESPN+ subscription due to broadcast rights agreements between the leagues and broadcasters, including ESPN.
