same thing, I don't even have a plan with the used Android for I picked up for $50. I use the Vonage app whenever I'm in WiFi so I hardly use any of my cell minutes on my other cell phone. (yes I have to have 2 phones this way)

So I could make a 911 call if needed from my Android without a plan in case of an emergency?

Also what's the best prepaid data service to go with?
