SAR doesn't need to use just one. They can try and get it in touch using any.

Signal & WhatsApp use the phone number as the identifier. So as long as they know the hikers number. They can try get in touch over both.


You would need another SAR person just to try calling on all the different apps.

Any that assumes spammers/scammers don't figure out a why to call with those as well and the callee doesn't just ignore those too.


Once have the hikers phone number and a message to send, it can be automated, until get a response.
Spammers/scammers can't hide their phone number.
