I just learned about this, too. It turns out that in the US, being an iPhone user is cool and being an Android user is lame, and you can tell who's who in group chats, because the messages that go over iMessage are represented with blue speech bubbles and the rest are in green bubbles.

That's not quite how it works. You can't have a group chat that's mixed iMessage and SMS/MMS.

If an iMessage user creates a group chat where not everyone is using iMessage, then it's MMS. I suppose now it could be RCS if everyone's using a device and carrier that supports RCS, but I haven't kept up with that. MMS has a bunch of limitations relative to any modern internet messaging app, so people don't want to use that.

Some people are also very reluctant to install third-party messaging apps.

Thanks. I don't actually have an iPhone, so my freshly acquired "knowledge" of this was based on reading about it on the Internet and I misunderstood what I read.
