The satellite phone's menu icons in order from top left to bottom right are: GPS, "Home" symbol, Files, Clock, Phone, Settings, Mail, and Uplink. Below that is a hazard sign that says: "INTERNAL ERROR". And below that still is: Calendar, Email, Tools, Main, Dock, Weather, Stocks, and Text. The phone was receiving a signal strength of "three bars" and is touch sensitive.
As Jin holds the phone, a side profile shows that it is almost certainly an Iridium 9500 satellite phone. A false screen has been placed on it for the close-up shots.


The phone had a signal so does that mean that it was just the batteries were dead?
