What a great film! I rented it with modest expectations but was held in suspense from beginning to end. Forget about "why" or "how" the communications are taking place, and concentrate on the plot and character developments. There are lots of interesting plot twists that made this movie a touching and at times terrifying experience. Far better then Sliding Doors, Ghost, or the Sixth Sense. Don't overlook Frequency for a great combination of mystery, drama, thriller and suspense!
