- Tips:
Please try submitting another address for you E911 information on the website.
Go to the My Settings section of your online account: https://tello.com/account/my_settings
Under the “WiFi Calling” section, click “Edit” below Emergency E911 Address.
Fill in your address and click on Save.
Now go to your phone’s settings and make sure that WiFi calling is enabled.
Lastly, we would kindly ask you to test the WIFI calling activation with your Primary SIM disabled on your device.
