One Call Alert offers a good variety of systems that provide in-home and outdoor protection. They include good choices for active older adults who enjoy ground travel within the United States.

The lack of caregiver tools makes One Call Alert less appealing to people who would benefit from having a family member apprised of their billing, usage, and battery life.

The systems that run through AT&T’s cellular service are not good choices for people who live in or spend lots of time in areas where cellular service is spotty.
