If you want to listen to online radio on the Nokia E75 then you have to create a .ram file. The first thing you need to do is to download the .pls file from the official site of that station.
Open the file with a notepad and copy the http address which will look something like this http://live.eliberadio.ro:8000. Open a new file with notepad and paste http address and then save the file with that ending .ram.
Now copy the file on your Nokia phone. This tutorial is valid for any type of phone, not only for the Nokia E75, that has RealPlayer installed.
