Http Proxy Injector

HI guys, i have a question. so in our country we don't get have a good internet connection with good pricing, with all the tax we don't get a good internet packages.mostly we have a content based plans.most of them are for social media and messaging platforms.we have to pay for the package and after fare usage policy(mostly likes 5GB) and when the fup exceeded we get to have unlimited usage for 1mbps.because of we don't have the money for paying high internet packages we use the http proxy injector created by a-dev1412 developer (https://sourceforge.net/projects/httpproxyinjector/).first we create ssh account using free ssh account making sites.after that we use the server name indicator(SNI) for routing the all the network traffic for devices. if i have a unlimited 1mbps package for whatsapp i use the sni web.whatsapp.net. this method is only available for android and windows there are no alternatives or similar software for linux.i wonder if there anybody know how to use that method in linux
