How can I bypass the Activation Lock on an iPhone 5s without the previous owner's information?

Activation Lock is a security feature designed to prevent unauthorized use of an iPhone. If you do not know the previous owner, there are very few options available to bypass it. 1. If you have the original proof of purchase from an authorized Apple retailer, you can contact Apple Support to request an activation lock removal. Without documentation, Apple will not assist you. 2. You can try to contact the previous owner through the carrier, though privacy laws often prevent carriers from sharing account details. 3. Replacing the logic board with one that is not iCloud locked is a hardware solution, but for an older device like the iPhone 5s, the cost of parts and labor usually exceeds the value of the phone. Be cautious of websites or services claiming to bypass the lock for a fee, as many of these are scams and cannot provide a permanent unlock.
