Not sure, actually – I wouldn‘t be surprised if a helicopter would actually still appear if I‘d press the big red button on mine, but I haven‘t tried.

False alerts are probably a real concern. I had to provide two emergency contacts for the service I‘m using. The operators will call them before dispatching emergency services to catch accidental activations.

A big problem with stolen phones, is that the thieves are often kids, and use the 911 (999, in EU) feature to call in false emergency calls, as that is the only thing on a locked phone that works.

Really, phones are a bad bet, for stealing, these days; especially Apple kit.

In EU, the universal emergency number is 112, not 999. I think the later was UK specific once, but in the UK 112 will also work [0].
