Overview

• Voice and data for O2/Telefónica and Vodafone users collapsed after antennas on a heating-plant chimney were removed for demolition at the end of June.
• Fernwärmegesellschaft Baden-Württemberg says it terminated site contracts and warned operators years earlier, while local officials and businesses report their alternative site offers drew no response.
• Vodafone announced a mobile mast as an interim solution, targeting largely restored coverage by mid-September, and Telefónica says it is examining a similar temporary setup.
• Operators cite the steep, forested valley for siting delays, as tourism firms and facilities report daily disruptions and safety gaps such as nonfunctional sauna emergency buttons.
• Many customers say special termination requests are rejected because systems show no fault despite the mast’s removal, leaving landlines, Wi‑Fi and walkie‑talkies as stopgaps.
