Well, it's trivial for the app to simply add a flag that there is a photo or video in the encrypted content. End to end encryption doesn't mean the app doesn't know what you're sending, it means the company can't decrypt the contents.

But that does not explain how the WhatSim guys can detect multimedia content and charge accordingly. They can't decrypt the traffic and can't modify the app itself.
I think (it's been a while since I looked at this) the multimedia traffic goes to a different set of whatsapp servers.
If the APP itself taks care of monitoring when pix and videos are sent, then the SIM doesn't have to. And since the SIM is only for use with the app, your problem is taken care of.
The SIM and the app are different companies, that's not going to happen. WhatsApp will never associate themselves with WhatSim.
Ah, I was unaware of that, thanks.
