Your eSIM device isn’t connecting to the network? The behavior of your device in the network is not as expected, e.g. when roaming, using network slices or applets to switch the network? You suspect issues related to the eUICC and its profile data?
Unlike traditional SIM cards, where physical access allows direct debugging, eSIMs are permanently soldered. That means no easy way to intercept the communication between the eSIM and the device. This lack of visibility creates a major problem for mobile network operators (MNOs), and manufacturers of devices, chipsets, and eUICCs (EUMs). If something goes wrong, troubleshooting is often a long and frustrating process of trial and error. But what if you could see exactly what’s happening between the device and the eSIM?
This document outlines a strategy to troubleshoot network-related issues in eSIM devices by making the hidden communication between device and eUICC visible.
