Why do I open an account in Essence Securities, and my mobile phone is always disturbed by the business calls of other securities companies, saying that we can cooperate to make money together?

This should be normal. The securities company will not disclose your phone number and your personal privacy. Maybe your phone number was leaked from other places. Think about it. If you borrow these mobile phones, you will be scolded, and I think they will give you up. Hehe, I am. When I get similar calls, I just ignore them. When I get angry, I scold them and stop calling me!
