Good point. SMS is basically useless in my country as well as there are too many spams, even from the carriers themselves. This is one thing I wish Apple tackles, spam filter. Google Messages has a spam filter and although it’s not perfect, it helps a bit.Resurrecting this thread - I just realized that one of the big reasons I don’t use iMessage even with people who I know use an iPhone is the fact that the app is absolutely cluttered with SMSs - OTPs, transaction notifications, spam etc - I currently see in excess of 500 unread “messages” because I just glance at them and never open them. WhatsApp is definitely more restricted to “real” communications and thus what I turn to.
But yeah, things like this is one of the reasons people move to services like WhatsApp, although it’s getting a bit out of hand as well as now many businesses in my country send their OTOs through WhatsApp.
