Would a signal booster help here?
Only sometimes. A booster amplifies a signal that already reaches your roof, window or car; it cannot create coverage. If a phone held outdoors in Utah shows no bars, it has nothing to amplify. It helps where a usable outdoor signal dies indoors. Check that outdoor signal first, and match the booster to your carrier's bands, not to a headline range figure.
