This paper analyses the impact of substitution between fixed and mobile telephony on call prices. We develop a model where consumers differ in the benefits of mobility and firms price discriminate between on-net and off-net calls. We find that call prices are distorted downwards due to substitution possibilities and customer heterogeneity, and that this distortion increases with the fixed-mobile termination mark-up.
