Nokia 2125i / 2126i / 2128i

I am hoping that I am just not understanding something basic here on my 2128i but I swear I have combed the users manual and still don't know how to make this work. I have typed in all my list of contacts - so I would expect that when one of those people call me - that their name shows up on the display. But no - when someone calls me who's name and number is in my contacts list - the only thing that shows up on the display while the phone is ringing is the number of the person calling.

Is this the way Nokia does things? This is my first Nokia phone - I am coming off of an LG VX4500.

Any suggestions or help thanks!
