Is there any FOSS alternative messenger that handles SMS and RCS? Supposedly RCS is an open standard, but I am not aware of any FOSS messenger that has it. I’d like to move away from google messenger, but there doesn’t look like there is an option just yet.
I went through this same process recently. Since Apple was finally implementing RCS, I was looking forward to my iPhone friends complaining less, but unfortunately it seems like Google pretty much has an iron grip on RCS as even with Samsung Messaging or Beeper / Sunbird, I’m pretty sure you need a Google Account
as a beeper user, i can confirm that the rcs feature of google messages does not work w/o google play services
