content: It depends on where you live. During Katrina and a handful of other events the cell networks go down and only POTS connections or VoIP with large battery back ups worked. Not to mention the phone having a batter back up or not needing a battery. One podcast I listened to the host talked about getting trapped in an elevator after an earth quake because all the power went down. He went through over 100 names in his contact list before finding someone who answered. However anything more than $15 a month for a land-line is over priced.
