Release R1.2 of the COMPRION eSIM Tracer – a tool that visualizes communication between eSIM/iSIM and the device – expands the translation options. Instead of just showing raw data from the Card Application Toolkit (CAT) commands, they are now interpreted and displayed in an understandable way.
Users can immediately see what type of command is being exchanged between the eSIM/iSIM and the device – for example, whether the eSIM is initiating a call, sending a short message, or transmit data to remote servers.
New features at a glance:
- Translation of Proactive Commands (TERMINAL PROFILE, ENVELOPE, FETCH, TERMINAL RESPONSE)
- Breakdown and interpretation of COMPREHENSION-TLV Data Objects (first version)
Who is this relevant for?
The eSIM Tracer with the new translation of Toolkit Commands makes the work easier for M(V)NOs, chip, module, and device manufacturers, EUMs, and IoT solution providers – basically anyone who wants to ensure that communication between eSIM/iSIM and the device works correctly.
