My partner went to Mississippi after the hurricane to help out. She was part of a team that went from our EMS service. They brought a Satellite phone with them. She said it just didn't work....No idea if there 'wasn't a signal' or if it was something else but she said that for 2 days it wouldn't work. She also said that the other agencies (not affiliated with us) also had sat phones and theirs wouln't work either. I'd rather spend the money elsewhere personally.
