- First confirm whether you have an active commitment period — in the operator’s customer area. Cancelling during the commitment period may incur a penalty (legal exceptions exist, e.g., unemployment or emigration).
- The official channel is the Plataforma de Cessação de Contratos (cessacaodecontratos.pt), managed by the Direção‑Geral do Consumidor — you authenticate with a Digital Mobile Key or Citizen Card.
- The process on the platform has two steps: request for contractual information and then the termination request (denúncia).
- You can also terminate directly with the operator — via the customer area, a store, a letter or the support line. Always keep proof of the request.
If you disagree with the charged amount, appeal to a Consumer Conflict Arbitration Center — it is free.
