A turned off mobile phone is not essentially invisible, as it can still be detected by certain technologies. For example, law enforcement agencies and intelligence services have the capability to track the location of a turned off phone through advanced surveillance methods. Additionally, if the phone has a removable battery, it may still emit a low-level signal that can be picked up by specialized equipment. Therefore, while a turned off phone may not be easily visible to the average person, it is not completely invisible to certain technologies. **
