COMPRION has launched its eSIM Tracer, a software solution that enables recording and analysis of communication between mobile devices and soldered eSIMs.
“In an era where more and more devices are equipped with built-in SIM cards – so-called eSIMs or iSIMs – the eSIM Tracer offers a much-needed solution for mobile network operators (MNOs) and chip/device manufacturers to precisely analyse problems before market launch or in the field and thus identify and eliminate critical causes of errors,” explained Olaf Rethmeier, Product Manager eSIM Test Solution, COMPRION.
The challenge with eSIMs is that they are permanently soldered and therefore no physical SIM card interface is available. This means traditional diagnostic methods for analysing communication between the card and mobile device fail. However, analysis remains essential and trial and error processes can be time-consuming, COMPRION has developed the eSIM Tracer as an answer to this.
The software solution consists of universal monitoring software and specific ADPU tracing adapters that can be integrated into existing test environments. The ADPU tracing adapters are tailored to the respective chipset model of the end device and allow communication data to be recorded.
The eSIM Tracer software accesses communication data flowing between the eSIM and mobile radio module in real time. The recorded ADPU commands are structured and displayed in a clear way that enables detailed analysis of the interactions between the device and eSIM, including context-sensitive translations, making technical data easy to understand.
An adapter compatible with Qualcomm’s processors was developed, as they are used in a wide variety of mobile devices. Adapters for other chipsets and manufacturers are currently being planned.
