Hey samantha.l23! I'm so sorry you're bumping into this error message, Wi-Fi calling can be so helpful at home.
Are you following the steps next to ER101 at the bottom of the page here: Wi-Fi Calling problems? What type of phone are you using? Is it a new device, or did this work before and recently stop?
