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.
I’m in Italy and as long as you have the phone number, you can just use whatsapp. It’s the de-facto standard and everyone has it. I really don’t understand the problem.
