SIM function is integrated in modem chip in the production process. No physical SIM card is required.
Operator data profiles are loaded in a secure process at the time of module or device manufacturing.
Chips and modules with built-in SIM OS and operator profiles enabled by RedteaSIM are ready to connect.
Since the additional SIM card is no longer required, the associated manufacturing, logistics and inventory costs are no longer needed as well. The maintenance costs (i.e. costs created by physical visits to swap SIM cards) can also be effectively reduced.
Compared to multi-chip designs, RedteaSIM improves power efficiency since no separate SIM component needs to be operated, which is especially applicable to IoT devices that are intended to be used over a long period of time.
There is no SIM slot and no need for physical SIM space in the circuit board footprint, so that more space can be freed up to allow simplified PCB design and allow devices to keep small and lightweight.
The integrated RedteaSIM can protect against extreme environmental conditions (temperature fluctuations, humidity, vibration, dust, and moisture, etc.) across the long lifecycle of IoT devices than legacy plastic SIM cards that are removable.
SIM functions being integrated into chipset at the time of module or device manufacturing results in huge savings over the exponential complexity needed for scalable IoT deployments in more difficult-to-reach areas.
By programming operator profile directly into the modem chip, RedteaSIM can help IoT applications cost-efficiently connecting a large number of devices in a wide area, and get instant connectivity without any additional actions.
RedteaSIM streamlines the SIM lifecycle by reducing spend in managing the SIMs and at the same time increasing data subscription, and thus can efficiently manage IoT devices over their complete lifecycle.
RedteaSIM provides the functionality to receive and process an encrypted data profile which behaves exactly like a classical SIM. Further more, the integrated RedteaSIM can’t be easily accessed, helping to reduce the risk of theft, tampering, and cellular data abuse.
We’re joined by the leading operators, chipset and module manufacturers, and solution providers to practice the integrated SIM technology. For example, we have engaged in the joint effort to introduce nuSIM, the integrated SIM for IoT. The joint solution was developed in accordance with Deutsche Telekom's open nuSIM specification and consists of a trusted application from us in a Quectel BG95 module containing a Qualcomm® LTE 9205 chipset.
