Regulation (EU) No 531/2012 of the European Parliament and of the CouncilShow full title

Article 13 Retail charges for regulated data roaming services

1. Roaming providers shall make available and actively offer to all their roaming customers, clearly and transparently, a euro-data tariff as provided for in paragraph 2. This euro-data tariff shall not entail any associated subscription or other fixed or recurring charges and may be combined with any retail tariff.

When making this offer, roaming providers shall remind those roaming customers who have already chosen a specific roaming tariff or package of the conditions applicable to that tariff or package.

2. With effect from 1 July 2012, the retail charge (excluding VAT) of a euro-data tariff which a roaming provider may levy on its roaming customer for the provision of a regulated data roaming service shall not exceed EUR 0,70 per megabyte used. The maximum retail charge for data used shall decrease to EUR 0,45 per megabyte used on 1 July 2013 and to EUR 0,20 per megabyte used on 1 July 2014 and shall, without prejudice to Article 19, remain at EUR 0,20 per megabyte used until 30 June 2017.

Every roaming provider shall charge its roaming customers for the provision of any regulated roaming data service to which a euro-data tariff applies on a per-kilobyte basis, except for Multimedia Messaging Service (MMS) messages which may be charged on a per-unit basis. In such a case, the retail charge which a roaming provider may levy on its roaming customer for the transmission or receipt of a roaming MMS message shall not exceed the maximum retail charge set in the first subparagraph.

3. From 1 July 2012 roaming providers shall apply a euro-data tariff to all existing roaming customers automatically, with the exception of such roaming customers who have already made a choice of a specific roaming tariff, or who are already on a tariff which is demonstrably lower than the euro-data tariff or who have already made a choice of a package by virtue of which they benefit from a different tariff for regulated data roaming services than they would have been accorded in the absence of such choice.

4. From 1 July 2012 roaming providers shall apply a euro-data tariff to all new roaming customers who have not made a deliberate choice to select a different roaming data tariff or a tariff package for roaming services which includes a different tariff for regulated roaming data services.

5. Any roaming customer may request to switch to or from a euro-data tariff, respecting their contractual conditions, at any point in 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 Union-wide 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-data tariff may always be combined with a euro-SMS tariff and a euro-voice tariff.

6. By 30 June 2012 roaming providers shall inform all their roaming customers individually, in a clear and understandable manner and on a durable medium, about the euro-data tariff, that it will apply from 1 July 2012 at the latest to all roaming customers who have not made a deliberate choice of a special tariff or package applicable to regulated data roaming services, and about their right to switch to and from it in accordance with paragraph 5.
