Creating a 4g proxy with android box or raspberry pi

Hey guys,

With a dongle and SIM card how can I create a proxy so that I can add ip:port username and password in Jv on my vps?

The android box or raspberry pi will be local in my home and on 24/7

Can someone explain how and which apps I need?

Don’t worry about data cost on SIM card.

You have to install an app called proxy server
