Beyond my outright jellousy of your sat phone collection. I am curious to know if there is any isuses with sat upgrades and tecnonology compatability. Are the older sat phones outdated or has the technology for satilite phones prity much sabilitzed since the sucers were put in to orbit.
Even though the older sat phones are no longer in production they are fully functional. Motorola and Kyocera also made some satellite pagers (out of production) and those are functional as well. The only Iridium phone in current production is the 9555. There are advantages of each model. For example the 9505a is physically tougher phone then 9555.
