Good thing nobody uses sms to chat here where I live…

The bad thing is that Whatsapp is the alternative.

The thing is, RCS isn’t SMS. That’s kind of the point. RCS is a replacement for SMS. The two protocols just happen to be available in the same Messages app. It’s like sticking WhatsApp inside Messages, except it’s a different protocol.
Oh I get it, but well, my point still stands, nobody here uses the stock messaging app, which can send SMS.
Same here… whatsapp became so widespread, that even governmental agencies and private businesses use it for official communication.
That is what blew my mind indeed, and as someone who hates constantly dialing companies and such for minor crap, I kinda am glad they went this way lol.
