Hi @Ere1, sorry to hear about this.

I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

As this is a service that is offered by your operator, please get in touch with them to make sure that both your subscription supports this and that is has been activated there.

Let me know if that helps!
