I still don't get why people use SMS/MMS anyway? I've been using WhatsApp for ages now and so does everybody else in my country - and every country I've been in, apart from China and Japan. My friend who's from the US once said "I've paid for those text messages, so I'm going to use them!" But if I send him a text from Europe to the US, I pay 1 damn euro per delivered text. WhatsApp is free! Is there any viable reaso…
SMS is the only federated messaging system guaranteed available on all cell phones. That makes it more useful than any walled garden.
Sure, if I want to send someone videos, or do regular group chats, I'm going to find an alternative platform. But if it's just a casual contact, or I don't anticipate needing these things, I'll just stick with SMS.
