Restricted Wi-Fi

Hi there! So I'm on a restricted WiFi network and most android apps and sites are blocked/denied on the connection, regardless of wheather I use VPNs or not.

For apps I can download the app via Google store, no problem but when I load the app it says there is no connection. Websites are unreachable, messanger won't send or receive messages. My VPN app won't even connect to any server.

So my question is, can I set certain apps to use my mobile data plan and not the WiFi so the apps/sites will work.

I tried this in - settings /mobile network/data usage/network access, There are options to allow specific apps to be granted access to Mobile Network or WiFi. I deselect WiFi, and still no connection.
I could use my mobile Internet all the time, but my monthly data usage is limited.
Thanks.

 

I think I solved it. I tried onion over vpn, that didn't work. I tried a variety of obfuscated servers, still no luck. In the end I used a double vpn which seems to do the trick. Latency is a little bit of an issue but I can live with that.
