LOG OUT

Hello Timmy,

The answer is not super straight forward as the iPhone is likely set up with more than just the previous owners Apple ID. There are security features that help prevent erasing or using a stolen Apple device. I understand this was given to you and not stolen but you will want to contact the previous owner as they likely have some steps to take to let you fully own the iPhone.

What to do before you sell, give away, or trade in your iPhone, iPad, or iPod touch - Apple Support

"If you no longer have your iPhone, iPad, or iPod touch

If the steps above weren't completed and you no longer have your device, use these steps:

1. Ask the new owner to erase all content and settings using the above steps.
2. If you're using iCloud and Find My [device] on the device, sign in to iCloud.com/find or the Find My app on another device, select the device, and click Erase. After the device has been erased, click Remove from Account.
3. If you can't follow either of the above steps, change your Apple ID password. This won't remove personal information that's stored on your old device, but it prevents the new owner from deleting your information from iCloud.
4. If you're switching to a non-Apple phone, deregister iMessage. 
5. If you're using Apple Pay, you can remove your credit or debit cards at iCloud.com. Choose Account Settings to see which devices are using Apple Pay, then click the device. Next to Apple Pay, click Remove.
6. Remove your old device from your list of trusted devices."

I hope this helps.

You can generally put yours in.

If you're trying to update an application or authorize a computer for iTunes Store content, only the one stored inside it will be accepted.

If you've encountered the activation lock, it can only be activated by the Apple ID involved or having Apple bypass the lock.
