I have a straight talk home phone (different from a straight talk cell phone). It sounds just like the verizon home phone that was described earlier on this thread as it is a small "box" with a small cell antenna, a 110v power supply, two standard phone jacks, an internal backup battery, a voice mail indicator light, a signal strength indicator light, and a battery level indicator light, free unlimited long distance, free caller ID (number only- no name) and free voice mail. $17 a month ($15 before taxes). My unit uses Verizon cell towers. They have a deal going on right now where you can get a free reconditioned unit along with one month's service. I have had it for about 7 months and have no complaints. Last week, I unplugged it from the wall and took it to my parents house to show them how well it works (there was good signal there too). I suppose a person could even use it as an ultra cheap emergency cell phone ( unplug it from the wall outlet and carry it and a cheap "bell type" phone in their vehicle).
Funny thing was calling att and cancelling the landline. Typically it took 3-4 days to get a repairman out to fix static on the line. The landline was dead within 60 seconds after I hung up with customer service.
