The vpn server itself is pretty easy you either lease form a company that preloads it or you use a linux image and learn to configure it.
The much harder problem is figuring out which ip/servers are subject to the cap limitations and which are not. You would have to find a hosting company that had servers that for some reason where outside the cap. In many cases it is just cheaper to buy more bandwidth from the ISP that is limiting you.
Pretty much if it is simple for you to find the company will also know about it and block it.
So try to learn about hosting services in general and see if any are even a option. If they are very determined to block you they may have manually put in a list of IP addresses that are not subject to the cap.
Thanks you for your reply
But I can't understand your response because I'm not expert in the hosting server
Anyway I can explain my situation I use 4g connection wich is illimited of volume but speed is changing (to 2mb )daily if I reach some gigabytes ,the career trick the clients.
Recently I remark that time loading of sites is very fast for 2mb
In another sites of measuring speed it reach 15 mb or more just for seconds and go down to 2mb like the career restrain the speed.
But in speed test.net the career can't restrain the connection speed and stays to 15 mb connection that make me conclude that I can bypass the restraining
Okay my Question if someone has a trick to use my full connection potential
