If any major conflict happened, the sat phone downlinks to terrestrial land lines would all be taken out. US military uses them to much. When the service was going to go bankrupt due to lack of demand, the military stepped in and propped them up. This is one of the few areas where I think corporate welfare is OK. Sat phones provide a needed service that isn't otherwise available.
