Hello, I am involved in planning a digital ID app for the government. We are aiming to provide various personal information through this app, including the consideration of including the user's phone number. During the app installation process, we can collect the accurate user's phone number through SMS verification. However, I'm curious if there's a way for our app or server to detect when a user changes their phone number after installing the app. I understand that Apple's policies prevent us from automatically collecting the user's phone number. However, it would be beneficial if we could at least know if the phone number provided by the server differs from the current phone number on the smartphone.
