Ever move your phone number from one sim to another?   Phone providers only requires a few details to do this for you.    

Credit card number 

Old Address 

Last four digits of SSN    

These details are often seen in large database leaks. If a malicious attacker has this info they can have the phone carrier and migrate your number to another sim.   

If they get through the first login screen of an account the code gets sent to their sim with your number.
