And keep in mind 911 doesn't work on Iridium so have some numbers programmed in. The cell phone revolution seems to have rendered actually remembering someone's phone number a lost art.
This is untrue. 911 does work on Iridium and is handled by an outsourced company called Intrado. Additionally, you do not need an active account or SIM for 911 to work. Which makes an Iridium Sat phone a great emergency back-country tool.
Also a good way to make an IED trigger. In that case, you reallly don't want a telemarketer to call when your doing the final arming stages.
