1. Roaming providers shall make available and actively offer to all their roaming customers, clearly and transparently, a euro-SMS tariff as provided for in paragraph 2. The euro-SMS tariff shall not entail any associated subscription or other fixed or recurring charges and may be combined with any retail tariff, subject to the other provisions of this Article.
2. With effect from 1 July 2012, the retail charge (excluding VAT) for a euro-SMS tariff which a roaming provider may levy on its roaming customer for a regulated roaming SMS message sent by that roaming customer may vary for any regulated roaming SMS message but shall not exceed EUR 0,09. That maximum charge shall decrease to EUR 0,08 on 1 July 2013 and to EUR 0,06 on 1 July 2014 and shall, without prejudice to Article 19, remain at EUR 0,06 until 30 June 2017.
3. Roaming providers shall not levy any charge on their roaming customers for the receipt by them of a regulated roaming SMS message.
4. Roaming providers shall apply a euro-SMS tariff to all existing roaming customers automatically, with the exception of such roaming customers who have already made a deliberate choice of a specific roaming tariff or package by virtue of which they benefit from a different tariff for regulated roaming SMS messages than they would have been accorded in the absence of such a choice.
5. Roaming providers shall apply a euro-SMS tariff to all new roaming customers who do not make a deliberate choice to select a different roaming SMS tariff or a tariff package for roaming services which includes a different tariff for regulated roaming SMS messages.
6. Any roaming customer may request to switch to or from a euro-SMS tariff at any time. Any switch shall be made within one working day of receipt of the request, shall be free of charge and shall not entail conditions or restrictions pertaining to elements of the subscription other than roaming. A roaming provider may delay such a switch until the previous roaming tariff has been effective for a minimum specified period not exceeding two months. A euro-SMS tariff may always be combined with a euro-voice tariff and a euro-data tariff.
