Re: Emergency call
I've mentioned several times that I do volunteer work for seniors. One of them recently bought one of those fall alarm / panic switch type devices, with my help picking it out. She's an artist, paints portraits, mostly of bearded men (yes, she's done one of me). When we were discussing the pros and cons of wrist mounted versus pendant around the neck style, I pointed out that waving her arm around like she was painting broad brush strokes, might be misinterpreted as wildly waving your arms around as you fall down. My comment was accompanied by appropriate mimed arm movements. She went with a pendant.
It can be programmed with five numbers, it'll call each in sequence until it gets a result. The recommended sequence is family members, trusted friends, doctor / nurse / other designated care person, then emergency services if all else fails. Those five designated numbers can also phone the device, but otherwise doesn't allow incoming or outgoing calls.
The only ongoing cost is for the SIM and phone calls (depending on plan).
I can't recall the battery life, but way longer than 18 hours, that's pitiful. Yes, it has a GPS, water proof, and other features I can't recall off the top of my head.
She is very pleased with her new pendant, and has been extolling it's virtues to the other seniors. Two of them where complaining about their devices being broken, so they need to buy new ones. I pointed out to them they should probably buy a different brand, those brands are obviously not robust.
