Oh I agree with you, and that's something I forgot to mention - if you do SMS/MMS routed through Fi, they downscale everything. Forget 4k video - any video you take is getting repackaged as a .3gpp file at very low resolution (144p? idk, it's pretty bad). Audio-only clips are similarly compressed a lot, and very noisy as a result. Images don't seem to be affected, but I haven't tried sending anything big.

It's not useless, but vastly better for short text conversations than anything else. Not surprising, it's SMS.
