At the moment there seems to be a problem with O2 calls. The provider already reports that they are researching the cause under high pressure.
Complaints are currently increasing throughout Germany that calls are being disrupted by all mobile phone providers. The “All disturbances” portal indicates that the reports are piling up equally at O2, Vodafone and Telekom. However, the cause seems to be O2 – because the disturbances all relate to the Telefonica network.
O2 names faulty server as the cause
O2 spoke up on Twitter and wrote: “There are currently possible restrictions on telephony in our network. Telephone calls in 2G and 4G mobile and landline networks are affected. We are working on restoring the service as soon as possible.” A special page of the provider collects all the news about the situation.
As the cause of the disruption, O2 calls a faulty “voice server” that transmits the phone calls. Many phone calls are currently being redirected, so there should be fewer problems. Customers are correspondingly annoyed – because the hotlines of the providers cannot be reached either.
The disturbances apparently mainly affect the GSM and LTE networks. There are also initial reports of failures in the 5G network, even if they are not nearly as frequent and O2 does not explicitly mention 5G.
Vodafone and Telekom confirm the failures, Telekom wishes good luck via Twitter. There it says: “Telekom’s mobile network is not affected by this disruption. We’re keeping our fingers crossed for our colleagues in Munich that the disruption can be rectified quickly. Separate in color, united in substance.” Vodafone also commented on the difficulties in reaching O2: “There are currently restrictions on mobile telephony in the direction of Telefónica. Our technicians are working on a solution for you. So that everything will soon be running as before.”
Failure of emergency numbers
The reports on “All disturbances” come from all over Germany, and police and fire brigade control centers are also affected. Hamburg citizens are currently being informed via Katwarn that the emergency calls 110 and 112 are currently out. The police tweeted: “At the moment there seems to be disruption throughout the Hamburg telephone network. In some cases, both some of our departments and the emergency call 110 are affected. As soon as communication by telephone is reliably possible again, we will contact you.” The same can also be heard from Bremen.
