If you have an Apple device logged in to the account then Apple uses its own push notification infrastructure instead of SMS. Apple calls it “Trusted Devices”: https://support.apple.com/en-us/HT204915 https://support.apple.com/en-us/HT204915 Also, SMS is always in-addition to your password. If you forget your password and you don’t have a trusted device from which to reset it, then Apple uses a recovery procedure which requires more than just SMS for verification. You can also enable a recovery key which will then prevent SMS from being used to reset your password. With a recovery key you need to either use a trusted device or the key to reset your password.
