What state are you from? It depends on how your own box can be activated.
In the area of Vodafone West/ex-Unitymedia (NRW, BW, Hessen) you have to contact the customer service and transmit the CM-MAC and serial number. The provider device is then also reclaimed. You will receive the telephony access data by post within a week, but you can also access them at any time in MeinVodafone.
In the rest of Germany (Vodafone Deutschland/ex-Kabel Deutschland) you will receive the online activation code in the order confirmation, with which you can activate the device in the online activation portal together with your customer number. The telephony access data will be displayed to you and you should save it as a PDF or print it out so that you always have it to hand. You must keep the provider device and this must always be connected in the event of a fault and remain connected until the problem is finally resolved.
