The EU is concerned about high costs for consumers using their mobile phones in other countries, called international roaming. The European Commission has made a proposal on how to regulate international roaming. The European Parliament’s Committee on Internal Market and Consumer Protection has issued an opinion on the European Commission’s proposal. The Committee draws on a report from Copenhagen Economics, in which we have reviewed the Commission’s proposal. We suggest several changes to the Commission’s proposal. For instance, the European Commission has proposed two retail price caps when making a call: one for calling home or a third country (45 eurocents), another for calling locally in the visited country (30 eurocents). In our review of the Commission proposal, we do not find justification for two price caps, and we propose a single price cap (39 eurocents).
