I'm in Norway, one of the countries where most people don't use SMS.
As a result, there are some people I can only chat with on Facebook Messenger, some people I can only chat with on Telegram, some people I can only chat with on WhatsApp, some people I can only chat with on Snapchat, some people I can only chat with on Signal, and some people I can only chat with on Discord.
I'm not sure that's so much better than a single standard which everyone on every device on any software platform can integrate with.
