As many other successful technologies, cellular telephony has

diffused in an s-shape in most countries. Theory suggests a number of reasons for this, including word-of-mouth, consumer

heterogeneity and network effects. Using quarterly data from 42 countries over 6 years, we propose a test to distinguish

between these diffusion theories that have previously been difficult to discriminate. We find that consumer heterogeneity and

network effects have played important roles in determining the speed and shape of diffusion of cellular telephony.
