How do delete profile by zuludest managment profile ?

You might want to start out by explaining how the profile got on your device. Who put it there, who owns the phone, is this a work or personal phone, how old are you; just in case you are a child and your parents installed this? Since it mentions education, are you using Wi-Fi from an educational institution and they have placed it there to restrict web access? You will need to provide a lot more detailed information about this situation, and I believe you know a lot more than you are telling.
