Samsung Tocco F480 asking for network code?

[namake_mono49]

I purchased a Samsung Tocco F480 from ebay and have just switched it on to find a page asking for a network code, is this just because it's locked? it hasn't been stolen or anything right?

You can purchase network code to unlock your Samsung phone from any commercial vendors online like WickedUnlock.com
