Fair point. Currently, everything that requires off-site backup is sent to my father’s Synology using hyperbackup. So off-site is sorta self-hosted already. Was thinking in terms of a second fallback option.

My wife and I increasingly wish we lived overseas!

I didn’t think about that. I’ve only ever used it for 2 things, and only one of them was a new number. That was over 10-years ago.

Honestly, I’ve been using GVoice for a long time as a replacement for my land line. It doesn’t even ring anywhere. It’s the number we give for things like gas rewards and such. It’s been great. I’m actually amazed Google hasn’t killed or enshitified it yet.
