Does it work without a smartphone nearby?

Yes. It has its own 4G LTE connection, so SOS alerts, fall alerts, location and two-way calls go through the watch itself. You still need an active cellular plan for the watch.

How does fall detection work?

The watch senses a fall and can trigger an alert automatically, without the wearer pressing the SOS button. Like all accelerometer-based fall detection, it can miss some falls and can occasionally alert on a hard sit or dropped watch.

Can family see where the wearer is?

Yes. GPS location tracking is built in, so caregivers can check the wearer's location through the companion service. Location accuracy depends on GPS and cellular signal.

Can you talk through the watch?

Yes. A built-in microphone and speaker support two-way voice, so the wearer and a caregiver can speak directly through the watch.

Does it track heart rate and steps?

It monitors heart rate from the wrist. It is a safety device first, so fitness and activity tracking are basic compared with a fitness smartwatch.

What do I need to set it up?

An active 4G LTE plan for the watch and the companion app or service for caregivers. Check that the carrier's network covers the wearer's area before relying on it.
