I haven't seen it maybe there's an app for it. But in my opinion it's not necessarily because you have to charge it anyway. (If you track your pulse and use always on Display the battery won't work a hole Day!)
In addition, the smartwatch offers sleep tracking, fall detection, forecasts and records for the menstrual cycle and tracking of over 40 sports activities. i am a man therefore no experience
I have the Bluetooth version, but I think the LTE needs an E-sim, so not a physical one.... You should be able to request the E-sim from your provider on the same number...
Samsung watches would be the best choice as they have fall detection and are compatible with iOS and Android devices. And of course, they are waterproof.
So the item mentioned is one of the best choices for the elderly.
