Before ordering an eSIM please check if your device is eSIM compatible. If the answer is YES, then go ahead and place the order. Login to My Account - My SIM section and scan the QR code with your phone's camera. Make sure you are connected to a Wi-Fi network as you will need a steady Wi-Fi connection to complete the eSIM activation. Please note that once you start the activation process your Tello service will be temporarily inactive. Don't worry, your service will resume once the eSIM is active on your device.

If you want activate your Tello eSIM from outside the US, please note the first thing you need to do is set up WI-FI Calling in your Tello account and phone. To set up WI-FI Calling, follow the steps available in My Account - My Settings section.
