Activation help

If you are not the owner and do not have the Apple ID and Password then there is no way that you can get into this iPhone unless the original owner shares the Apple ID and password with you. If you are lucky you can get into this iPhone if they (owner) or their family members accidentally remove the device from their Apple ID.

Late? Sorry, I do not understand what you mean.

But if the iphone is locked to a previous owner, only that owner can help you.
