Fun hole in Hamm: O2 customers are waiting for a solution for almost a year!
In downtown Hamm, O2 customers have been confronted with a real dead zone for almost a year. The network coverage that many users take for granted leaves much to be desired in this busy area. In November 2024, the mobile phone provider Telefónica had to dismantle its radio mast on the Kaufhof building because the building had to be handed over rent-free after the sale. This measure meant that customers had to wait for a solution that would only be available in the first quarter of 2026 in the form of a new cell site. A spokesman for Telefónica, Florian Streicher, confirmed that a replacement location in the immediate vicinity of the old location has already been identified, while details about the owner and the exact location remain unclear.
According to the spokesman Lukas Huster, the city administration of Hamm has no direct influence on the expansion and availability of mobile networks. Nevertheless, the city shows understanding for the restrictions of the users and welcomes the priority that Telefónica grants the location search. Many residents and users of the mobile network still have to prepare for a few months, while Telefónica carries out modernization measures at other locations in Hamm, for example on Hafenstraße and on Caldenhofer Weg.
Network expansion and 5G modernization
The situation in Hamm comes at a time when O2 Telefónica in other regions of Germany takes tremendous steps towards a better mobile network. In the past three months, the company has implemented around 2,000 expansion measures to improve network quality. Especially in cities such as Cologne, but also in other metropolises such as Berlin, Hamburg, Munich and Frankfurt, 5G coverage is further condensed, how [TelefoniCa.de] (https://www. Telefonica.de/news/corporate/2024/03/chleunigter-netzbau-im-ersten-quartal-202-oz-netz-waechst-um--bestml) reports.
With 5G, O2 currently reaches 95 percent of the population, which means good news for digitization. More powerful 5G and 4G/LTE networks not only support the everyday life of users, but also the entire digital infrastructure. Last year, a whopping 4.8 billion gigabytes were smuggled through the O2 network. These impressive numbers show how essential the network expansion has become for society.
A look into the future
The good news for the O2 users in Hamm could soon arrive. Telefónica plans to continue the network expansion in the coming months, and with the construction of a new mobile phone status in the first quarter of 2026, a piece of network quality could finally return. While O2 already records progress in many regions, it remains to be seen when the users in Hamm can count on a stable connection again.
In summary, the continued expansion of Telefónica's mobile network is not only necessary but also urgent to meet the needs of users and ensure smooth access to the digital world. It remains to be hoped that the challenges in Hamm will soon be a thing of the past.
