The following section provides details on the structure for csv files to be used by partners that wish to transfer pricing data to HBS over the HBS Portal GUI. As mentioned above, this option for pricing data transfer can be used by partners that are unable to implement the eRoamingDynamicPricing webservice. Furthermore, partners interested in flexible pricing only can skip implementation of the eRoamingDynamicPricing webserviceand rather use the functionality provided in the HBS portal for uploading and downloading tariff data.
