Tariffs: Tariffs are the frame for the relationship with the customer. Thus, one SIM card cannot have more than one tariff attached to it. In order to be counted as a product, per GCB definition, a tariff has to fulfill the following requirements:
o The tariff has to define a basic price for all possible types of calls or data access that are offered to the customer. This may include a fixed monthly fee or bundles of minutes/data usage.
o The tariff is the most basic form of a price plan that a customer can choose. Thus, it must not require any further tariff options to be fully functional for the customer.
