The Clue Goes outside of coverage?
The Answer ROAMS
The answer "ROAMS" fits the clue "Goes outside of coverage" because to roam means to move around freely or wander. When someone roams, they often go beyond a specific area, which can relate to being outside of a coverage zone, like a phone service area. In this sense, roaming implies leaving a designated space or limit. Thus, it connects well with the idea of going outside of coverage.
