In fact, the associated tariff, under the terms of which the “maintenance of the PT telephone number” (portability) is charged €2 (2 euros) per month, was deemed to be incompatible with the Portability Regulation - Regulation no. 58/2005, published on 18 August 2005.
This determination was adopted following the adoption of the corresponding draft decision, approved by determination of 6 April 2006.
