Pros: i use the pre-paid calling cards ,i don't have to deal with a service ,so buy time for it when you want.
Cons: it doesn't get a very good signal if you're around hills or anything.
Summary: I like the design of the nokia 1600 it is small and managable enough that you easily carry it in your pocket. It does pick up pretty well in most cases. It has a unbelievable battery, seems like it stays charged up for the longest time. Overall I think it is a good cell phone.
