I was a signal user until 2021, something glitched, probably because I had a weak data signal a few times so I thought signal was glitching so I abandoned it.

Well I need it again now because starting today July 6th Google is monopolizing all my native SMS apps and I don't like the vibe of that and I do not agree to click agree to every step of the process Google taking over all my SMS activities.

As far as I know the only way to use Signal is if both communicating parties are both on signal, so how can I make this my main SMS app with businesses and everything & everyone who texts my main phone number?

I don't have a lot of friends and so far I have one friend who agreed to go to signal with me, and I texted him and he didn't respond so I thought he either ghosted me or it's not working. How can I make signal work? It's not working.
