How to you block a number from contacting you?

i'm on 02 and i need to block a person from sending me texts and being able to call me,



i don't want to change my sim card.



please helpHow to you block a number from contacting you?
i would either say create a profile for that person where they wont have a way to notify you or alert you someone is calling, or call your phone company and explain to them why you need them blocked.



or get a restraining order against them lol and that will make them stop contacting you, lol hopefully you dont have to go that far.



hope i helped!
