That’s the same issue everyone has/had, including me. You’d be surprised how alright it works to use SMS and phone calls once you get used to it. It’s honestly refreshing. You don’t have to go that far, necessarily, as there are other messaging services out there that I’m sure your circles find better than SMS.

Sure, you might miss out on some events and stuff due to others needing to remember that you’re no longer on Meta platforms, but just be a little persistent and they’ll remember to include you, just like they did me ;-)
