Blocking the Samsung internet on Galaxy S2

Hello people. I am making some drastic changes in my life and would like to restrict the internet/disable it, but, have the only option to connect to works wi-fi and nothing else. I can block other browsers, as you can disable them, but Samsung internet is hard to remove or block. Does anyone know of a way (that's no rooted yet) where I can only connect to works internet and nothing else? AND block Samsung internet.
