I was watching something on my phone and turned off my WiFi so that cellular data could load it instead (which was quicker at the time). But if it can use both separately then why can’t my phone do both at once and load things faster?

In theory, they could.
There are already hardware devices called a dual-WAN router that do exactly what you want, for your home network.
Now, not every connection could share both. If you have a connection between your phone and some server that stays running, like while streaming a video, for example, there isn’t really a way to send half of the data across a different path.
But, there are many cases where some traffic could be sent over cellular and some over wifi.
So why isn’t it done?
I don’t know for sure, but here are some thoughts:
1. It’d add complication, and one more way for things to go wrong. Is it really worth it?
2. The vast majority of the time, one of the two is clearly better. Almost always, wifi is much faster and lower latency if available. So it wouldn’t be worth it.
