What are the Message Delivery Areas (MDAs) for the Iridium paging service?

Iridium divides the world up into geographic regions called Message Delivery Areas (MDAs). MDAs are fixed geographic locations that donít change and may be land, sea or air based. Customers select MDAs so that the Iridium network knows where to deliver paging messages.
