For critical industry processes and applications Telefónica Deutschland and Crout launch Resilient Connectivity Solution

When monitoring cold chains, securing cash transports, transmitting vital data, or activating backup systems, the connection must never be interrupted. Telecommunications provider Telefónica Deutschland has gained a new partner for the Internet of Things in the German company Crout. Together, the companies are now launching the “2CoreSIM” on the market: an IoT solution that combines two independent network profiles on a single SIM card and automatically switches to the alternative connection in the event of disruptions. “Digital processes are becoming increasingly business-critical for companies. Anyone who monitors the flow of goods, transmits medical data, controls security systems, or operates backup systems needs connectivity that works even in the event of a disruption,” says Jörg Kablitz, Chief Partner & Wholesale Officer at Telefónica Deutschland. “The partnership with Crout demonstrates how strong networks, IoT expertise, and intelligent SIM technology come together to create a solution that gives companies greater reliability and operational control.”

“Crout develops IoT solutions for companies that view connectivity not as an add-on, but as part of their core business,” says Frank Kiesewetter, CEO of Crout. “If temperature data doesn’t arrive, a logistics problem becomes a quality risk, or if video surveillance and alarm systems fail, this can lead to immediate security risks and financial consequences. Even wildfire and flood early-warning systems only work if alerts are received in a timely manner. Together with Telefónica Deutschland, we are therefore bringing resilient connectivity to places where outages are particularly costly, risky, or business-critical. The solution reduces complexity and embeds reliability directly into the SIM card.”

The technical core of the solution lies in the SIM card itself. It can automatically switch between two eSIM profiles without requiring companies to install additional apps or manually configure their own profiles. This is where the product name “2CoreSIM” comes from. If the primary connection is unavailable—for example, due to a lack of cellular coverage, local disruptions, or major system failures in the core network or IT infrastructure—the SIM activates the alternative profile. Control takes place directly on the card, which is built into the respective IoT device. The solution thus goes beyond traditional roaming. It relies not only on multiple cellular networks but on two separate network profiles and infrastructures. In the future, the SIM will be able to integrate various network layers—terrestrial cellular networks, satellite-based connections, and short-range radio.

The 2CoreSIM is suitable for applications where stable connectivity is essential for operation. In logistics, high-value goods, containers, or cash-in-transit vehicles can be continuously monitored. In the food retail and pharmaceutical logistics sectors, temperature data from cold chains can be transmitted more reliably. In healthcare, resilient connectivity supports the transmission of vital signs and device data. In industry and security, sensors, machines, security systems, and backup solutions remain accessible even if the primary connection fails. Pumping stations, water treatment plants, and oil and gas pipelines are provided with uninterrupted connectivity to safeguard continuous supply. In flood monitoring and wildfire detection systems, the 2CoreSIM ensures that alarms are reliably received.
