Work through these checks
Confirm the provisioned flow
Available flows require provider provisioning, an inserted SIM and Iridium connection. An empty list alone does not identify a hardware fault.
What the result means: Record flow name, enabled state, observed time and affected client. Keep network details private and ask the service provider to confirm provisioning.
Check the client path
Compare the installed VLAN and gateway with the authorized network plan. SDF VLANs have no terminal DHCP; caching DNS and firewall/port forwarding are unavailable on SDF.
What the result means: Use authorized read-only checks. Preserve VLAN, subnet and security policy; do not enable a new flow or generate paid traffic to test it.
Interpret indicators and capacity
SDF does not show GUI data arrows. Enabled provisioned flows stay active and share the Certus 200 total capacity with background IP; extra flows do not multiply bandwidth.
What the result means: Record flow name, enabled state, observed time and affected client. Keep network details private and ask the service provider to confirm provisioning.
When to stop and get help
Use authorized read-only checks. Preserve VLAN, subnet and security policy; do not enable a new flow or generate paid traffic to test it.
What to tell support
Record flow name, enabled state, observed time and affected client. Keep network details private and ask the service provider to confirm provisioning.
