Work through these checks
Read the actual SIM or PIN warning
A red power LED can accompany a missing SIM, SIM PIN requirement or Terminal PIN requirement. Read the Web Console message before concluding the SIM is defective.
What the result means: Record exact warning, firmware, registration/data state and time. Keep identifiers and credentials private; give evidence to the service provider.
Locate the failed connection stage
For registered-but-no-data, compare signal and APN with the provider’s settings. For an active session without Internet, check local Wi-Fi and whether the installed firewall permits the required traffic. Do not disable protection as a workaround.
What the result means: Keep one metre clear of the transmitting front. Use authorized access; preserve firewall and APN settings. Do not guess PINs, factory reset or run paid tests.
Save both system-log files
Web Console Settings > Terminal Info > Logs > Export All Logs supplies CSV and BIN system logs. Save both privately for authorized support. Do not pull the battery to shut down: the manual warns that this prevents logs being saved.
What the result means: Record exact warning, firmware, registration/data state and time. Keep identifiers and credentials private; give evidence to the service provider.
When to stop and get help
Keep one metre clear of the transmitting front. Use authorized access; preserve firewall and APN settings. Do not guess PINs, factory reset or run paid tests.
