Uhm... I have an old version and theres just a little cover at the back. Have you tried this? http://ee.co.uk/help/phones-and-device/ee/Osprey-from-EE/Osprey-from-EE-Getting-started
You have to register your sim card before you can use it, do that by putting it in the box, connecting to the box via usb or wifi, and going to add-on.ee.co.uk

O. From a quick google it looks like yours has a removable cover (the coloured one that goes around the corners). Try removing that.
