Hi, I thought I've lost my phone, so i bought a new one. About 2 weeks later I found my old phone so I have decided to sell my old cell phone. The thing is, when I got my new cell i had to get a new sim card so the sim card on my old phone does not work anymore. If i sell my old phone with the sim card that does not work, would the person who is buying it be able to reuse that sim card without buying a new one? Thx =]
