I was referring specifically to using the text messaging system, not the Internet.

You still cannot send livephotos via Whatsapp/Telegram. They convert to still photos. So you still lose something there.

MMS limitations are only relevant because Apple makes them relevant. I have never sent or received an MMS outside of the iMessage interoperability context. This is obviously deliberate.

You can send whatever you want through SMS, as a link.

What do you think those have to do with SMS/MMS?

The GP comment is about sending media between iPhone and Android, and claims that that is limited by MMS. That’s obviously not true. And has nothing to do with SMS/MMS.

Huh? Sending MMS between any two devices is pretty clearly limited by MMS.

Sending media isn't.

Other mechanisms of sending media are entirely irrelevant to a discussion about using MMS and the technical limitations of the MMS spec.

We're not in that discussion.
