The quickest and most convenient way to find out if we have a better solution for you or how to cancel your services, is speaking with someone from our specialized helpline.

Please check in your contract if you are still within your loyalty period.

If you cancel your service before the end of this period, you may need to pay a value that varies depending on the offers you received and the remaining months of the contract.

If you are within the loyalty period, you can check the amount to be paid in the my NOS app or customer area. Our expert will also give you this information.

Based on the information provided by the NOS specialist, including the estimated amount to be paid and the service deactivation date, among others, you will need to submit a written cancellation request to us.

The final bill will depend on the date you formalized the cancellation. If you cancelled within 10 days before the end of the billing period (which you can check on your bill), your services will be active for an additional month. For example, if the billing period ends on January 20th, to avoid paying for an extra month, you must submit the cancellation request by January 10th.

Once we receive the written cancellation document, we will send you an SMS to your primary number within 3 business days, confirming the reception and scheduling of deactivation date of your services.

You have a 30-day period after the service deactivation to return the devices that belong to NOS. If you fail to do so, you will be required to pay compensation for the unreturned devices.

The easiest way to cancel your service is to ask for a free call from someone on our specialized team. Alternatively, you can call 931 699 000 or 16990 and choose the Deactivation option.

Alternatively, you can make the request in person or by mail.

Gather the following documents:

• Contract Termination Request Form. This form must be signed by the person in whose name the contract is held, and the signature must match the one on your identification document;
•  Copy of an identification document with a signature. If you do not want to send a copy of the document, you can only send the termination form. In that case, your signature must be notarized or certified by a lawyer. Alternatively, you can visit a store and fill out the Personal Data Confirmation Form with the presentation of your identification document.

The documents can be:

• sent through our email form by selecting the option "Enviar documentos para cessação contratual"
• delivered at a NOS Store 
• sent by post mail to Apartado 52111, EC Campo Grande, 1721-501 Lisboa.
