Can I sell my iPad that I have had for over a year. But is not paid off? If so I imagine I need to take out my SIM card, right?
It is always good to know your options when selling your devices, we'll be glad to help. In this case, yes; you can sell your device as long as it is not active on the account. If the devices are still active, the person that purchases them won't be able to activate them.
