> SOS is only possible with a monthly plan

Is that allowed? In normal cell coverage areas, emergency calls are routed by law even without a SIM card.

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].

Yes, because satellite phones are not normal service. Both immersat and iridium connect 112 and 911 to their own operator who will then try to contact authorities where you tell them you are. I'm not surprised that this isn't available unless you're on a monthly plan.

Not unless that’s changed recently. The last time I tried with Iridium (when in an actual emergency) calling 911 wasn’t supported in any capacity. I had to call someone else and have them relay my call.

Well, this article from 2014 says that all satellite providers support it through operator connection:

That link actually says only 2 of 4 supported 911/112 in 2014. It explicitly states:

> You will need to obtain the full international access code, country code, and phone number for the local fire, police, or ambulance depending upon the nature of the emergency and store it in your contacts.

for Thuraya and Globalstar (at least back then).

Either way, I said Iridium didn’t and apparently I was wrong (as my example was from 2016). Maybe I had a Globalstar phone that time? Iridium definitely didn’t in 2008 though.

Since the only reason most people have a satphone is for emergencies, what would pay for the service if emergency calls were free?
Having had a satphone it got used for quite a lot of stuff, never for an emergency.
With something like a Garmin inReach, the service is turned completely off if you're not subscribed, so even an SOS message wouldn't be transmitted through the satellite
