INWATS (INward Wide Area Telecommunications Service) WATS service for incoming calls, only, INWATS was a discounted bulk long distance plan in the United States and Canada that reversed the charges to the called party, rather than the calling party. Although INWATS service, as such, has been obsoleted, toll-free services are common throughout the world. Such services are toll free only to the caller, of course.
