@aral My mom downgraded from Google Hangouts to SMS (which I have to use Google Voice to send/receive) and wouldn't install Signal becuase her phone is old and completely out of space (which is also why Hangouts stopped working).
So it went from bad to worse.
At least I have my girlfriend, most friends, and even a brother of mine all using Signal. 🤷♂️
But ugh. SMS. Really? 😢
