We’ve identified an issue affecting G3 SIMs (ICCID prefix 8946*), where new data sessions and usage are not being reported in real time. As a result, affected SIMs may appear disconnected or without recent activity in the dashboard, even while actively passing data. Connectivity and traffic are not impacted, but session and usage reporting are delayed in our systems. Our engineering team is actively working to restore normal reporting behavior.

The issue has been mitigated, and usage and session data are now processing normally. It may take several hours for all delayed records to fully catch up. We’ll continue monitoring system performance before marking this incident as fully resolved.
