Of course! Just check the status of your contract with your current operator. In the case of a fixed-term contract, you can submit an order to transfer the number at the earliest 120 days before the end of its term. Do not break it earlier if you do not want to pay penalties – select the "at the end of the contract" option in the form.
If you know that your contract has already been entered into for an indefinite period, select the "with notice period" option in the order form to avoid financial penalties for breaking the contract.
Remember that only the number owner can transfer the number. If the phone number is not registered to you, no worries! That’s when number cession comes in handy.
