I am sorry to address to you in English, I hope you can help me with my questions.
I would like to know if by subscribing to "Internet Light abonnement", I can on a later stage (lets say, 3 months after the start of my subscription) change this to a more complete service, like "Internet Basis", or Internet + TV? Does this involve any extra cost and reset of the contract duration?
Thank you for your help,
