Subscribers have the right to receive itemised bills on request at no extra cost (date, start time, number called, type, location, duration and units). Providers must let users communicate and request services from any terminal free of charge using alternative payment means (credit, debit or prepaid cards); those communications do not appear on the subscriber's bill; bills do not show the last three digits of numbers called, the full numbers being available only to contest specific charges, unless the Garante authorises full numbers once alternative payment means are available.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
