Management in the cloud

The NXTGN SIM Management Platform provides you with an intuitive interface for easy administration and management of NXTGN SIM cards. Cards and IoT devices are scalable and you can adjust tariffs and data volumes to your needs at any time. We place particular emphasis on fair pricing, as we believe that SMEs need tailored connectivity solutions that cover their requirements.



NXTGN SIM works on the basis of highly efficient radio technology

Depending on the application, different concepts for data transmission are required. Mobile assets require high energy efficiency with low data volumes, while real-time applications require high data throughput. NXTGN has the right connectivity concept for all requirements.

  • LPWAN: LTE-M or NB-IoT with 2G fallback
  • High traffic: LTE, 5G

NXTGN SIM cards communicate in all available mobile networks such as LTE, 5G, LTE-M or Narrowband IoT (NB-IoT). The choice of network is determined by the IoT application. Energy consumption, performance, building penetration, latency times or data throughput are the most important factors that should be taken into account in your decision.

We will be happy to provide you with a customised offer for your M2M or IoT application.



Gone are the days when remotely readable devices were equipped with expensive prepaid sim cards. The immeasurably large amounts of data that will have to be moved in the Internet of Things in the future demand efficient wireless network technology with low energy consumption, high range and low unit costs. New radio technologies have been developed for these so-called LPWA (Low Power Wide Area) networks. The two radio technologies (NB-IoT and LTE-M) are being developed and expanded by all major mobile network providers such as Vodafone, Deutsche Telekom and Telefonica on the basis of the existing LTE technology.

They are significantly more energy-efficient and enable reliable data transmission to the cloud even from difficult terrain such as basements, tunnels or vehicles and mobile transport. Especially for data-intensive applications and machine-to-machine communication, optimised LTE-M networks based on LTE technology are available for this purpose. The NB-IoT radio standard (Narrowband-IoT), on the other hand, is suitable for applications with small data volumes where high building penetration and particularly long battery runtimes are required.
