Description

Prerequisites

Bug Report Details

  • Version: v.0.9.0 (Windows installer)
  • Date: 2026.01.31
  • Region: Europe
  • Device: UZ801
  • What happened: Even without a Sim-Card having been put into the UZ801, the Test Heuristic seems to capture SIB1 messages.

  • Expected Behavior: A (inactive) SIM Card should be required.

  • Relevant logs: Occurred twice in my short time testing: 86407.zip 86407 (1).zip

Contributor guide

Research direction
Inspect the test heuristic code to understand why SIB1 messages are captured without a SIM card. Check if the heuristic checks for SIM card presence and trace the logic flow.
