BukkitPhones adds phone numbers into Minecraft. This allows the users to "call" each other and talk in a private chat. Everyone gets a unique 4 digit number, which can be used to call and receive calls. You can configure an emergency number in which your players can contact staff. The permission is still bukkitphones.911

I will be adding physical phones and probably service providers. Not sure if I will add the cell phone towers though. Thanks for the feedback.
I'd rather it be physical phones that you must craft and carry with you, Perhaps using a player head with a phone icon on it?
Heres more ideas:
Service fee to register your phone number or call somewhere AKA: Gold, Diamonds, Economy money...
Cell phone towers that you must be within range in order to receive or make phone calls.
