When does an activation work without a technician?
If a new activation by Deutsche Telekom is necessary, a technician will come to yours. If you take over an existing connection, a technician won’t be necessary, because the phone connection is already there. In case of a connection’s switch of technology, e.g. from cable to DSL, a technician's appointment is necessary. Please notice, that at least one phone number needs to be “port” for taking over a still existing connection.
You can avoid a technician’s date if you tell us the name and the phone number of the previous holder of the line, e.g. the previous tenant. Deutsche Telekom may has saved the correct digital line link and is able to make a so-called remote switching.
