Just to expand on my question. Here’s what I’ve tried so far:
Proxy servers - they’re all blocked.
Desktop apps that mirror my phone so I can just even work on the tiny screen on my desktop but USB, BT, and WiFi is blocked.
Embedding an editable gSheets widget on a google site (gSites aren’t blocked) - the embeded sheet wasn’t showing.
Jolicloud - blocked at work as well.
