Want to switch to a different provider or simply stop your current Sim Only plan? Cancelling is usually straightforward, but the conditions differ depending on the type of plan. In this article we explain how the notice period works, how to actually cancel, and what to watch out for.

Can you always cancel your Sim Only plan?

Monthly cancellable

Do you have a plan without a fixed term? Then you can usually cancel at any time, with a notice period of typically one month. You still pay for the current month, after which the plan ends.

Fixed-term contract

Still in a 12- or 24-month contract? As a rule, you can only cancel early without costs once the minimum contract period has passed. Cancel earlier, and the provider will often charge part of the remaining subscription costs.

How long is the notice period?

In the Netherlands, for telecom plans with a fixed term of more than 12 months, you're allowed to cancel monthly after the first year, even if the original term was longer. Does your contract continue automatically past its end date? Then from that point you have the right to cancel at any time, with a notice period of at most one month. If in doubt, always check the exact terms in your own contract, since details can differ per provider.

How to cancel in 3 steps

Step 1: Check your end date and notice period

Log in to your customer portal or check your original confirmation email for the exact end date of your contract and the applicable notice period.

Step 2: Cancel in writing or through the customer portal

Most providers let you cancel through a button in the customer portal or app. If that's not possible, cancel in writing (by email or registered letter) and keep proof that you sent it.

Step 3: Check the confirmation and end date

You'll receive a cancellation confirmation with the final end date. Check it carefully: if the date doesn't look right, contact customer service directly.

Switching with number porting: do you need to cancel separately?

No. If you request a porting (bringing your number along) with your new provider, that provider automatically arranges the cancellation with your old provider. You don't need to do anything yourself with your old provider.

What if you have to pay a penalty?

Cancel before the minimum contract period is over, and the provider may charge part of the remaining subscription costs. This is set out in the terms in advance. Wondering whether switching is still worth it anyway? Factor the remaining cost of your current plan into your comparison.

Common mistakes when cancelling

  • Cancelling too late, so the plan automatically continues for another period.
  • Cancelling only by phone without keeping written confirmation.
  • Assuming that switching with number porting automatically cancels your old plan without explicitly requesting it.
  • Not checking whether the confirmed end date matches what you expected.

Conclusion: cancelling doesn't have to be a hassle

Whether you're on a monthly cancellable plan or still under contract: always check your end date and notice period first, cancel in writing or through the customer portal, and keep the confirmation. Switching with number porting? Your new provider arranges the cancellation for you automatically.
