In order to use Wi-Fi Calling your Tello line requires an emergency address to be configured in My Tello » My Settings.
This is needed because if you call 911 over Wi-Fi Calling we may transmit your E911 Registered Address to the 911 Communications Center. This will help emergency responders locate you when you are unable to provide your contact information and current location. Please note, you will need to update your E911 Registered Address if you plan on using Wi-Fi Calling at a location different from the E911 Registered Address saved in your Tello account.
