Thousands of 1&1 customers in Germany reported significant disruptions in mobile and internet services over the weekend, particularly affecting major cities including Berlin, Frankfurt am Main, and Munich. The issues began around 9 PM on April 11, 2025, and peaked around midnight, creating widespread frustration among users who struggled with connectivity problems well into the next day.
Reports of service disruptions flooded in from various platforms, notably netzwelt.de and allestörungen.de, where more than 10,000 users documented their complaints. Many users pointed to issues such as a complete lack of signal, problems with mobile internet, and difficulties with telephone connections. The most affected areas included not only Berlin and Frankfurt but also cities like Hamburg, Stuttgart, and Cologne.
One user lamented, "I want to celebrate my birthday tonight. We need the internet for music. Let’s see if 1&1 can ruin my birthday for me." Another user speculated that the recent switch to 5G might be causing the problems, saying, "What’s going on now? Since the switch, there have only been issues."
As the disruptions continued into April 12, 2025, customers expressed their frustration over the lack of communication from 1&1 regarding the ongoing situation. Complaints ranged from no signal at all to intermittent connectivity issues, with reports indicating that around 40% of users experienced no signal, 33% had issues with mobile internet, and 28% faced problems with mobile telephony.
A spokesperson for 1&1 confirmed to t-online that a small portion of customers had indeed experienced temporary impairments to mobile services. They stated, "We can confirm that there were temporary disruptions in mobile services for a small number of our customers. The troubleshooting was carried out immediately and has already been completed." However, many customers remained skeptical, as persistent issues were still being reported on the morning of April 12.
Experts speculate that the disruptions could be due to technical problems or external influences, but no official statement from 1&1 has yet clarified the root cause. In the past, similar outages have often been attributed to network issues or maintenance work, but the scale and frequency of these current disruptions are particularly concerning.
In the competitive telecommunications industry, such outages can significantly impact customer satisfaction and trust in a service provider. 1&1, which is the third-largest broadband internet provider in Germany, faces pressure to act quickly and transparently to regain customer confidence. Clear communication regarding the causes of the disruptions and the steps being taken to resolve them is critical.
As customers wait for a resolution, the telecommunications sector is reminded of the importance of investing in infrastructure and modern technologies to enhance network resilience against such outages. Long-term solutions could help mitigate the frequency and severity of these issues, but for now, users are left hoping for a swift return to normal service.
In the meantime, 1&1 customers are encouraged to reach out to the company’s customer service, which is available 24/7 at the toll-free number 0721 96 00, for assistance with their connectivity issues. While the disruptions have caused significant inconvenience, the hope remains that 1&1 will address these concerns effectively and restore service to its users.
As the situation continues to unfold, both customers and industry observers will be watching closely to see how 1&1 navigates this crisis and what lessons can be learned to prevent similar occurrences in the future.
