Yup, I have skirted the expiration date a couple times with this SIM card and have brought it back to life. Having extra credit is what helped me, I think. I bought a bunch of minutes in February that I didn't use, because most of my calls were less than 1 minute. The majority of my calls went something like this:

"Hey Michael! Can we get a pick-up at Mirage? Going to Sun Beach. Thanks, Bye."

or

"Hello, Chicken Lavish? What time are you open til? 11:00pm? Great, thanks! Bye."
