如何订购和激活我的 Tello eSIM？
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.
在订购 eSIM 之前，请检查您的设备是否兼容 eSIM。如果答案是肯定的，请继续下订单。登录到“我的帐户 - 我的SIM卡”部分，然后用手机的摄像头扫描二维码。确保您已连接到 Wi-Fi 网络，因为您需要稳定的 Wi-Fi 连接才能完成 eSIM 激活。请注意，一旦您开始激活过程，您的Tello服务将暂时处于非活动状态。不用担心，一旦 eSIM 在您的设备上处于活动状态，您的服务就会恢复。
