dabunk, I have left my other one at our condo, and it still has minutes left on it after five months. I think once you buy add'l minutes, you have the same number for ever. If you don't buy minutes, they will take back your number after 3 months. Not sure, but I think this is how it works.

Live so that when you arise in the A.M, Satan shudders & says..
'Oh sh t..she's awake!'
