'(i) the extent, if any, to which the evolution of domestic retail prices is observably affected by the application by roaming providers of the domestic service rate to both domestic services and regulated roaming services throughout the Union' (b) Paragraph 2 is amended as follows: (i) The first sentence is replaced by the following: ʻIf the report shows that tariff options, in which the domestic service rate applies both to domestic and regulated roaming services, are not provided in all retail packages for reasonable use by at least one roaming provider in each Member State, or that the offers by alternative roaming providers have not ...[+++] made substantially equivalent retail roaming tariffs easily available to consumers throughout the Union, the Commission shall by the same date make appropriate proposals to the European Parliament and the Council to address the situation and ensure that there is no difference between national and roaming tariffs within the internal market

Such broad categories may be identified from current commercial practice by reference, for example, to the differentiation in domestic retail packages between pre-paid and post-paid customers; GSM-only packages (i.e. voice, SMS); packages adapted for different volumes of consumption; packages for business and consumer use respectively; retail packages with prices per unit consumed and those which provide "buckets" of units (e.g. voice minutes, megabytes of data) for a standard fee, irrespective of actual consumption.

However, roaming customers who before 30 June 2007 had already made a deliberate choice of a specific roaming tariff or package other than the roaming tariff which they would have been accorded in the absence of such choice, and who fail to express a choice pursuant to this paragraph, shall remain on their previously chosen tariff or package.

Roaming customers who already benefit from specific roaming tariffs or packages which suit their individual requirements and which they have chosen on that basis should remain on their previously selected tariff or package if, after having been reminded of their current tariff conditions, they fail to express a choice within the relevant time period.

When making this offer, home providers shall remind any of their roaming customers who, before 30 June 2007, had chosen a specific roaming tariff or package of the conditions applicable to that tariff or package.

Such specific roaming tariffs or packages could include, for example, roaming flat-rates, non-public tariffs, tariffs with additional fixed roaming charges, tariffs with per-minute charges lower than the maximum Eurotariff or tariffs with set-up charges.
