: This is the only 100% safe and legal way to unlock your phone for free. If you have paid off your device and your account is in good standing, providers like T-Mobile and others are required to unlock it upon request.
If you are stuck on an "Activation Lock" screen, "free" third-party sites cannot bypass this. Apple's security is server-side.
Even if the service fails to unlock the device, many third-party sites have strict "no refund" policies, often offering only "store credit" that cannot be used effectively.
