I don't have the previous owner apple account how can I activate my iPhone without the previous owner?

Question

What can I do to active my new iPhone 5s if I don't have the previous owner apple ID because I don't know him.

Answer 1

So the trick here is at what point are you getting stuck? You'll know whether or not you can use the device after you've restored it in iTunes. If the previous owner had not removed their iCloud account (or turned off Find My iPhone) before you do this, then the phone is forced into Activation Lock (which you'll likely see after restoring the device, upon setting it up). If this is the case, you either HAVE to contact the previous owner and have them help you type in their password or remove the phone from their iCloud account by logging into iCloud.com, or if you can provide valid proof of purchase you may be able to get support through AppleCare or an Apple Store. Otherwise, see if you can return it! Good luck!
