If you go to the official N-Gage Need For Speed website and click on the "Competition" pack of cards near the bottom left corner of the site, you should receive instructions on how to claim a free activation code for Mile High Pinball, Reset Generation or Pro Series Golf. This contest opened unofficially earlier in the week and some people had trouble getting their code to work, but hopefully they've fixed things now that the compo page has officially opened. Incidentally, if your activation code begins with the number 0 (zero), make sure you enter 0 (zero) and not the letter O.

You can see a list of N-Gage-compatible phones and find out more about the N-Gage platform on the All About N-Gage FAQ page.

To use a game's activation code, install the demo of the game and then enter the activation code when prompted, which will unlock the game into its complete form.
