This started randomly: I am in USA. When I dial a number in Canada, before it rings, a message pops up on my display that says "number changed by sim: [new number]" and then it changes to the new number and dials it! This happens when calling any international number. The new number is to a scammer that already gets many complaints about this number. How did they get in my dialer? How do I get rid of them? Help!
