sir good morning this is syed i purchage one iphone second hand from one of the person but the iphone is lcloud locked how can i unlock the i phone how i get his icloud unlock

Neither we (just users like you) nor Apple can help you, sorry.

Activation Lock can be removed ONLY using the original credentials that were used to activate that device.

Without those credentials, that iPhone is useless to you.

The only way os for the original owner to remove the lock. That's it. No other way.
