Disable SIM swapping by default

> SIM jacking, or SIM swapping as it’s better known, is the criminal art of convincing telcos to port a victim’s number to a new SIM card controlled by the criminal

As I understand it, for convience, SIM swapping was introduced to allow customers to retain their phone number when transfering to another telecom company. Wouldn't the simplest solution be to have the option to disable Porting Authorisation Code (PAC) being provided for that account. To transfer an account, you would have to go back to the old-fashioned method. Cancel account, make new account, get new (non-transferable) number.
