Switching costs increase the rigidity of consumers demand and lessen competition between firms, effects that are particularly relevant in the mobile voice services market. This paper characterizes the most important mobility restrictive factors for consumers in this market, presenting specific examples and discussing their impact on competition. In addition, a survey was conducted to obtain data on consumption decisions by mobile voice customers in Portugal. The survey results suggest that switching costs represent more than 13 euros or 57% of the average monthly expenditure with these services.
