This makes no sense to me. I scheduled a callback for tech support, but thought I might as well ask on here just in case anyone else has experienced this.
I've already tried resetting network settings a million times, already tried replacing my sim multiple times, and now this is an issue not only on my old iPhone 6S, but also on a brand new iPhone XS Max.
This has to be some kind of problem from Koodo's back end that erroneously is limiting my account on 3G right?
Would appreciate any feedback from someone who's experienced something similar.

I would check if you have VoLTE add-on in your self service account. If you didn't, you can try to activate Vo Wifi on the iphone. Normally, that add-on would be added automatically when you activate VoWiFi.
If you had the VoLTE add-on, you can go to Settings >> Cellular >> Cellular data options >> Enable LTE >> Choose Voice & Data.
