Hackers Are Hijacking Phone Numbers and Breaking into Email, Bank Accounts
If I want to change my number to a new SIM, my telco requires me to log in, and fill in a form. If I forgot my password their email it to me.They don't have any offices open to the public, nor any hotline, and are really the cheapest alternative where I live, but it seems that their attempts to save money have resulted in them ending up with a securer infrastructure than some notorious ones from very advanced countries.
