eSIM is not supported on GL Cellular routers so far, neither Mudi nor Puli AX. We are analyzing the eSIM working process now, including eSIM profile download, clarify whether the router need to do the carrier certification, etc.
To have a good user experience, eSIM requires router to have Bluetooth module to connect with phone, while Mudi and Puli AX don’t have Bluetooth module. In future MIFI product, we will consider to support eSIM.
