How to bypass school Wi-Fi on MOBILE?

So i'm connected to my school Wi-Fi on my phone (iphone 6 if that helps). However apps like Instagram, askf=.fm, and facebook don't load threw the app because they are blocked, how can i get around this but still be using the app, instead of using like a safari browser and a proxy.

You can't. Just concentrate in school there will be enough time for that after school.
