The quickest and most convenient way to find out whether we have a better solution for you or how to cancel your services, is to contact our 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 have to pay an amount 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 expert, including the estimated amount to be paid and the service deactivation date, among others, you will then need to submit to us the written cancellation request.

The final bill will depend on the date you formalised 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 request document, we will send you an SMS to your primary number within 3 business days, confirming receipt and scheduling of deactivation date of your services.

You have a 30-day period after the service deactivation to return the devices  which are NOS property. Failure to do so, will entail paying compensation for the unreturned devices.

There are situations beyond our control that we would not want to happen. In these situations, you can terminate the contract with us without any financial impact on you.

As a sole proprietorship, you will not have to pay to cancel the contract before the end of the loyalty period if the person on whose behalf the contract is:
