Hi @Elenasaizmoron,

Thanks for your message.  You can cancel your subscription via Mijn Simyo. You can do this by going to Instellingen > Abonnement, if this is successful, you will immediately receive a confirmation email about it. You can also cancel your subscription by sending us an email at klantenservice@simyo.nl. 

Make sure you go through all the steps in Mijn Simyo. If you are cancelling your subscription before your contract ends you will need to pay a termination fee. You'll find your termination fee at the final step.

Greetings,
Seren
