Domestic providers shall inform all their roaming customers in a clear, understandable and easily accessible form about the possibility to opt for services referred to in the first subparagraph of paragraph 1. In particular, at the time of making or renewing a contract on mobile communication services, domestic providers shall provide all their customers individually with full information on the possibility to choose an alternative roaming provider and shall not hinder the conclusion of a contract with an alternative roaming provider. Customers concluding a contract with a domestic provider for regulated roaming services shall explicitly confirm that they have been informed of such possibility. A domestic provider shall not prevent, dissuade or discourage retailers serving as the domestic provider’s points of sale from offering contracts for separate roaming services with alternative roaming providers.
