Do you purchase iCloud locked devices? Follow

The iCloud activation lock used to stop anyone from using or activating a device that's been lost or stolen and as such, we do not purchase iCloud locked devices unless they can be unlocked by the account holder.
If they cannot be unlocked, we can only offer to recycle them for parts to keep them out of landfill.

If you are unsure on how to unlock your phone from iCloud please visit this link how to Turn Off My Activation iCloud Lock.
