1. Roaming providers shall ensure that their roaming customers, both before and after the conclusion of a retail contract, are kept adequately informed of the charges which apply to their use of regulated data roaming services, in ways which facilitate customers’ understanding of the financial consequences of such use and permit them to monitor and control their expenditure on regulated data roaming services in accordance with paragraphs 2 and 4.
Where appropriate, roaming providers shall inform their customers, before the conclusion of a retail contract and on a regular basis thereafter, of the risk of automatic and uncontrolled data roaming connection and download. Furthermore, roaming providers shall notify to their customers, free of charge and in a clear and easily understandable manner, how to switch off those automatic data roaming connections in order to avoid uncontrolled consumption of data roaming services.
