SIM cards are at the heart of all mobile communications. They enable smart IoT devices on construction sites, in manufacturing halls, and in transportation and logistics to transmit data to a cloud platform. Our SIM cards are optimized for use in the Internet of Things – they are resilient to dust, dirt and vibration, are temperature-resistant, durable, and can be integrated into any production process. This enables maximum coverage, performance, and ultimate flexibility for your IoT projects. 

To whichever environment your IoT ideas take us –
we have the right SIM card

SIM cards are at the heart of all mobile communication. When used in IoT projects, they must function under a wide variety of conditions. Therefore, they also have the most diverse requirements:

  • Robustness
    Whether in refrigerated warehouses, foundries, or containers on cargo ships, SIM cards must function reliably under wide-ranging conditions.
  • Flexibility
    They must support numerous network technologies, such as classic cellular, 2G, 3G/UMTS, 4G/LTE, 5G, NBIoT, and LTE-M, as well as combinations of these.
  • Longevity

    For many IoT projects, SIM cards must function for many years without maintenance or battery replacement.

  • Cost-efficiency
    Especially in massive IoT projects, where larger quantities of SIM cards are used, they should also be maintenance-free and inexpensive.

For this reason, we provide you with diverse variants of IoT SIM cards. In addition to the classic plug-in SIMs and SIM chips for soldering, we offer SIM solutions with special functionalities such as eSIM and, in the future, nuSIM for large, special IoT projects. All offer you connectivity in the best German network and the option of worldwide roaming. No matter what environment your ideas take us to – we have the right SIM.
