Before signing a contract, your operator must provide the information listed in articles L. 113-1, L. 222-3, and L. 222-6 of the Consumer Code. These articles describe the pre-contractual obligations which apply to all consumer contracts, including all contracts signed in-store, on-line, or by telephone.
Your operator must also provide you with the information listed in article 115 of the law from the 17 December 2021 concerning networks and electronic communications services.
Your operator must then provide you with a contractual summary, free of charge
The aforementioned pre-contractual information and the contractual summary are an integral part of the contract you sign with your operator.
When a distance contract is concluded by telephone, the professional must confirm the offer to the consumer on a durable medium. The consumer is only bound by the offer once they have signed it or accepted it in writing (link to article L. 222-4 of the Luxembourg Consumer Code).
