Iridium Certus Maritime Plans: Single Vessel and Shared Data
Iridium Certus is Iridium's broadband service, delivering data and voice over the global Iridium network with no coverage gaps, including at the latitudes where a geostationary service fades out. Choose a Single Vessel plan for one boat's own allowance, or a Shared Plan if the allowance is pooled across more than one terminal, then size the allowance to how the vessel is actually used.

Why Iridium Certus for maritime broadband
Certus is Iridium's broadband service, and it is used where an always available connection matters more than raw speed. The same terminal handles crew calling, vessel reporting and remote monitoring, and it keeps working at latitudes where a geostationary service starts to fade.
- Runs on the same global Iridium network as Iridium voice, with no coverage gaps
- Handles crew calling, vessel reporting and remote monitoring on one terminal
- Keeps working at high latitudes where geostationary services lose signal
- A pay-as-you-go entry tier for a vessel with minimal but essential data needs
The fine print, plainly
Good to know before you activate
- An activation fee applies to every new line; it is shown on the plan page.
- The 0 MB tier includes no data allowance; every megabyte used is billed at the rate on the plan page.
- Usage beyond an included allowance is billed at the per-MB rate shown on the plan page, and it drops as the tier size grows.
- The 300 MB tier is listed as a VSAT plan; the plan page states how it is meant to be used.
- Shared plans pool the data allowance across every terminal registered on the account.
- The minimum term is the one stated on the order, and ending early carries the fee stated there.
Hardware
Terminals these plans activate on
An Iridium Certus plan activates on a Certus-compatible maritime terminal. The Thales VesseLINK and the Cobham SAILOR 4300 L-Band system are built for this service, and a plan from this page goes live on either once installed.
