AT&T Prepaid Device Unlocking and Features

So I have a new phone I bought from AT&T prepaid and I know that the device unlocking policy for at&t prepaid is like 6 months. I like to have my phones unlocked when I can have it done, although I have no desire to leave at&t. So using the app called device unlock in my apps list after 6 months let's say I decide to unlock it. Still using at&t prepaid, now that the device is unlocked can I still use Features like rcs messaging, Wi-Fi Calling, and other network features?
