I read about WhatsApp and how people can't part with Meta because of it, however no one on my continent uses it. Why is it so popular in the EU and other parts of the world?
How do thing like rich media, groups, etc work on sms? All these features are baked into messaging apps over data...
https://en.wikipedia.org/wiki/Multimedia_Messaging_Service
Multimedia Messaging Service (MMS) is a standard way to send messages that include multimedia content to and from a mobile phone over a cellular network. Users and providers may refer to such a message as a PXT, a picture message, or a multimedia message. The MMS standard extends the core SMS (Short Message Service) capability, allowing the exchange of text messages greater than 160 characters in length. Unlike text-only SMS, MMS can deliver a variety of media, including up to forty seconds of video, one image, a slideshow of multiple images, or audio.
SMS does support group messaging too, but I don't know the term for the protocol there.
A long time ago (approx 14 years back) I remember switching from prepaid to an actual subscription that included data. Back then it was probably 150min/SMS and 200mb a month. When told about WhatsApp I could finally ditch SMS and not worry about certain limits. As WhatsApp also worked on WiFi I could send as much text messages as I wanted.
maybe ask the metric system?
