Telekom Move New Construction Costs + 300€ Credit

You only get the 300 for a completely new connection, there are costs of 799,- beforehand. You get 300 back from that if you make the initial contract with Telekom.

For me, this means: the 300€ also works when moving/taking along an existing connection.

I have to disagree. According to the building owner service: The building owner bonus for the internal house connection amounts to 300 euros and applies exclusively when booking or taking along a MagentaZuhause package S up to Giga until 31.12.2020. To me, that means: the 300€ also works when moving/taking along an existing connection. So much for theory. What is your experience?

Sure, the 300 € works – but only if you have the physical connection installed in your new house for 799 €. In a new building, it isn’t there yet.
