Maybe an alternative is to store the WhatsApp contact information of people who could help behind a password.
Then, if I need help, I can ask to borrow someone's phone on the street. If they don't have WhatsApp, I can just make a regular phone call instead.
The goal should be to send a single message with nature of emergency, what you need from them, and what they do like call police
I could see a private reference page with important info. Including checklist for various scenarios. That's what I thought you did. Then print out a copy and put in binder somewhere at home.
Is this really likely? I would guess only 70 year olds don't have WhatsApp.
Seems more likely you forget the impoprtant phone numbers because you never enter them manually.
I don’t see why you would care for Discord over whatsapp except that it’s what you happen to use already.
