Can I use Wi-Fi Calling over my travel eSIM's mobile data?
Generally no. Wi-Fi Calling needs an actual Wi-Fi network โ on most phones it won't run over another line's mobile data, including the travel eSIM's. Since the Airlivo eSIM is data-only with no voice number, it can't provide Wi-Fi Calling itself. Keep Wi-Fi Calling switched on for your home SIM and connect to Wi-Fi to make and receive calls on your home number.
