greenPhone Basic suits for customers that haven't need for a fixed network telephone connection.
Note that additional costs may be incurred for greenPhone Basic. If an electrician is needed, for example to set up Naked DSL, the provider will not assume these additional costs. If you are able to determine the landline phone number at your location, then this can be used to identify and order the greenPhone Basic signal. In this case, an electrician will not be needed to switch the line over to the new terminal.
