Abstract

Roaming indicators displayed on existing cellu- lar phones do not provide adequate warning against accidental roaming charges. When using a cellular phone within the local service area, a user may experience a loss of the local carrier signal tem- porarily, and pick up a competing "roamer" system signal without knowing it.
