Nummerbehoud after termination of contract

Good afternoon!

I have a 12 month contract with Tele2 since February of this year but I’d like to change provider because I find it is extremely slow to connect to the line both for calls and to browse the internet; it’s not always that slow, but it is too often and I start to find it quite annoying. 

My question is: I need to request the number porting online by the new provider, but it doesn’t give me the option to select an immediate porting, so it will probably ask Tele2 for the available date and it will fail the new subscription because it’s not 4 month yet till the date of ending. 

So I thought, can I cancel my subscription with Tele2 directly myself, so that the number will be free of any restraints, and then ask to the new provider to port that number to my new subscription?

I believe it should be possible, because the Dutch Market and Consumers (ACM) authority states that consumers have right to number porting until one month after the date of termination of the contract: ”U hebt recht op nummerbehoud tot 1 maand na de datum van beëindiging van het abonnement”, see link attached.

But on the phone when I asked a few weeks ago I was always told  that I would lose the number, that number porting before the end of contract is not possible etc. etc.

Now I know that if the new provider asks for the “afkoop” of the current contract by the old provider it’s definitely possibile, but because I need to complete the order online, I need to do the “afkoop” myself and free the number in some way, and then ask a classic porting to the new provider so it sees no date restriction and can complete the porting procedure.

Can anyone confirm that I can do it this way or do you have any suggestions?

I also thought I could request Tele2 to transform my subscription into Prepaid (I don’t know if that’s possible) so also in that case there won’t be any date restrictions but the number would still be active.

But still Tele2 should keep my number for at least 1 month in case of termination of the contract, so that I can in case request a number porting of my old number to a new subscription. It’s like this in whole Europe, and I could now find it also on the Dutch authority website, so do you confirm this?

Thank you for your attention and I wish everyone a nice Sunday!
