What Does “Update Apple ID Phone Number” Mean for iPhone Users?

When iPhone displays “Update Apple ID Phone Number” – it means Apple is reminding you to ensure the phone number connected to your Apple ID is up-to-date. If it’s an invalid or wrong number, there’s the risk that you can lose your account.
