Offer a compact cellular location beacon with a managed monitoring service, transparent monthly pricing, and recipient access through text-message links that require no app. The service would monitor device health and location freshness, send departure, arrival, prolonged-stop, low-battery, and emergency alerts, and clearly label stale or low-confidence positions instead of presenting them as current.

Recent reviews across several established products show the same reliability failures following operating-system and app changes. Affordable cellular modules and location hardware make a dedicated, independently connected beacon practical for a small initial deployment.
