How would you do that ...

[Ryan McGinnis]

Sounds like you're having to trust some kind of tech from the country you're going to, so with that in mind:

Buy burner phone and SIM with cash from some place where normal people buy phones and SIMs with cash.  Install Signal.  Done

For identification, have some code word that will be the first thing you send.  Maybe even have a duress code word, too.

Now there are some places this won't work.  Some places only sell phones that are pre-compromised.  If you know what you're doing you can probably flash it with GrapheneOS, though that would require buying a computer, in that country, too.  At some point you're probably in the "gonna be taking some serious risks no matter what" territory, unless you're working for MI6 or something.
