Have a newbie question....can cell phones be used outside of the University EP?

I have University, Nightlife, and OFB installed, but I don't see any sort of cell phone in the Buy Objects menus. I have GL installed and have to play TS2 through it's interface...at least that's what the game tells me...have to play the latest EP/SP....I can still go to the OFB business district and the NL district without any problems and everything works fine. I haven't sent anyone to college as I haven't got a teen that I've made in game right now.

All I want to do is have a cell phone...is this possible?

Thanks for any help!
