We had suffered from some kind of data breach, and I was advised to protect our phones from sim swapping. I have no idea how to do this. We have an iPhone 14 and an iPhone XR. Help! How can I tell if a Sim Lock is on? If it is not, how can I put it on?
iPhone 14, iOS 17
There is no way to protect yourself from SIM swapping on your phone. You need to add 2 factor authentication on your cellular network account; SIM swapping is done by the perp calling your carrier, convincing them they are you, and changing your SIM.
Are you sure it was a data breach and not a phishing message→Recognize and avoid social engineering schemes including phishing messages, phony support calls, and other scams
