Map a normal week
Describe where you go, who travels with you and how long you are away from a charger. Compare a mobile wearable with a home-only base on that basis. Do not buy a more complicated device simply because it has more features.
Ask about the exact network and location service
Ask which cellular network the model uses, whether a separate phone is needed, and how a monitoring operator obtains your location. Do not assume that GPS identifies your floor or apartment, or that a device has usable reception in every underground, indoor or waterfront setting.
Make charging part of the purchase decision
Have the provider demonstrate putting the unit in its charger with the hands and eyesight you have today. Ask what happens while the device charges and how a low-battery warning reaches you. A longer advertised battery life is not a substitute for a routine you can follow.
Try a real-life route within the return period
With the provider’s permission, test the places that matter to you. Include the lobby, your regular shop and an outdoor stop. Keep a separate emergency-contact plan for situations where the device cannot connect. A city guide cannot certify coverage for your particular journey.
