Your operator changes your contract

If your provider raises the tariffs applicable to your contract, you have a right to terminate that contract free of charge within a month following the first invoice with the changed tariffs. 

NB: The right to terminate a contract free of charge does not apply in case of an increase due to indexation (if stated in your contract).

If the operator changes the provisions applicable to your contract, he has to inform you about the draft changes at least one month before they are implemented. You then have a right to terminate that contract free of charge within a month after the changes become effective, if you do not accept the new terms.

NB: The right to terminate a contract free of charge does not apply if the modification of the contract is the result of an amendment to a legal provision.
