emergency phone provision

I would send the emergency text message to whatever number is recommended by the supplier of the cellphone for such purposes.

" HELP! SERIOUS ILLNES AT WURZLESHIRE VILLAGE HALL POST CODE XXXX YYY. SEND AMBULANCE" would suffice.

" HELP!  FIRE AT WURZLESHIRE VILLAGE HALL POST CODE XXXX YYY. SEND FIRE BRIGADE"

Seems that Apple do all the messages etc for you: https://support.apple.com/en-us/HT213426

Dial 911, if it can't connect via any network it will offer you the ability to send an SMS to 911 via satellite with all your needed info on where you are etc. Looks to be more for out in the wilderness than a town or city with no service because of storms etc.

That's great if you have an iPhone and aren't inside a semi Faraday cage. Our building used to have so much steel in it that you couldn't make a mobile call without going outside. texts all arrived when you were half way home

Granted, I started this querying it on a theatrical licensing type issue but since we abandoned POTS, our wall mounted phones are replaced by half that number of VOIP 'phones" for emergencies, none of which are in corridors or public areas.

All individual Vox calls require us to log onto our computer. Tricky when you're holding the right hand fingers in your left hand.

Thanks for the link and other info.

Looks like this service is not due to be available in the UK, though I consider it likely to be available in the future. Worth keeping an eye on, but of no near term help.

Sadly unless you have and maintain a satphone you will be accessing a cell tower and network before you get to satellite networks and still rely on ground networks to handle the connection to and emergency call handler who may or not be in your country.

When the London tube bombings happened the cellphones in London all went off. 

Does anyone know what happened to cell phones during the Manchester concert bombing?

The emergency message facility on some satphones us very simply a single text message to one number giving your GPS coordinates and a very short message, to someone who will be there and coordinate a rescue.

Disagree, as far as I can tell, the whole point of this new service is that the text signal travels DIRECTLY from the cellular handset to the satellite, without any use of the cellular network.

The main market is for emergency connectivity in remote places without any cellular telephone infrastructure.

Once the satellite communication company have your text message they will pass this on to the emergency services, in the right country, they already know your location. The link from the satellite ground station to the emergency services is presumably via landline, but these are duplicated and equipped with backup power supplies.

My impression was that this was an intentional move by the authorities, to preserve bandwidth for emergency services?

You may also find that isolating the cellular network during a terrorist event (or suspect event) could be done to prevent any further potential remote triggers being used.
