How to make a proxy server on Android phone without white ip for remote connection?

Question

Android

I need one high-quality proxy server and instead of paying 100 rubles once a week, buying it through a service for rent, I got the idea to make a proxy on my phone using the ip given to the phone when using the mobile Internet. Most likely there is a dynamic ip, but it will suit me every time to look at the phone address and write it down. What is the easiest way to solve my problem?
