I was going to sell my iPad Mini locked to T-Mobile and remove the sim card. I have a potential buyer that would like to buy it, but only if the original sim card comes with it. Have no idea why he would want it. My T-Mobile plan gave me 200mb data/month free for life so maybe that plan comes with the original sim card? I have no idea. Anybody know why he would want my original sim card? Am I risking anything by giving him the original sim card? Should I destroy the sim card or keep it with the sold iPad? Thanks for your help.
