Home Zone Region Definitions:
The Monthly Plans and Global Prepaid Plans presented above have global coverage except for a short list of countries that have opted-out of Iridium coverage. The Regional Prepaid Plans presented above provide service in a geographically-restricted Home Zone Region. There is a small percentage of instances where the geographic restriction will extend or retract from the Home Zone Region described here because the Iridium system interprets the call as originating from outside the designated Home Zone Region, and service availability is not guaranteed in these instances.
