The iCloud unlock is a permanent unlock that unlinks a device from the Apple ID. The unlocked device still sends the activation request to Apple Server, but it activates with no issues. However, iCloud unlock is not always possible. Users who do not remember their Apple ID passcode or have no receipt encounter problems when they try to recover access to their device.

The iCloud Bypass is a bypass of the Activation Lock on iPhone or iPad. In simple words, the bypass only skips the Activation step and makes the device understand that it has been activated. Please note that activation of the device occurs only once. It means that after bypassing the Activation Lock, your device will operate normally without any problems unless you reset it to factory settings.
