And now i want to activated this sim card, as a user, if i can
If the contract has been revoked, it cannot be activated.
You can call the hotline and ask if the revocation can still be stopped.

Hello @nnntt ,
welcome to the community.
If the contract has already been canceled with us, then the sim card can no longer be activated.
Then you have to sign a new contract.
Have you already been able to resolve your issue via the English hotline?
Best regards,
Maria
