I want to set a pin on my sim to prevent sim swapping/hijacking.
I was told by my provider (belong) to just do this on my phone.
I found the setting to set a pin on my iPhone but if my sim was swapped and the thief had a new copy of my sim would that pin still be on there?
No, that’s not how SIM swapping works. A SIM PIN will not block it. A SIM PIN will prevent someone who steals your phone from using your SIM in another phone.
SIM swapping means having your carrier switch your account to a new phone and a new SIM. One thing you can do which will make it harder to SIM swap is to add 2 factor authentication to your account with your carrier. It won’t prevent someone from bribing an employee of the carrier to bypass your 2 factor authentication in order to get an authentication code from another site. That’s why 2 factor authentication that uses SMS is not secure, especially if there is a lot at stake (such as access to a cryptocurrency account). Your timing is excellent; here is a blog post from Cybersecurity journalist Brian Krebs released today that includes the risks of using your phone number on websites: https://krebsonsecurity.com/2021/04/are-you-one-of-the-533m-people-who-got-facebooked/ and another from a few weeks ago on SMS security: https://krebsonsecurity.com/2021/03/can-we-stop-pretending-sms-is-secure-now/
