Why is Wi-Fi Calling not working while I use a travel eSIM?
Wi-Fi Calling belongs to your home carrier's number, not the data-only travel eSIM, and it needs a real Wi-Fi network plus a carrier that allows it abroad. Make sure Wi-Fi Calling is enabled on your home SIM (Settings → Cellular → your home line → Wi-Fi Calling), that you're connected to Wi-Fi, and that your carrier permits Wi-Fi Calling from abroad. The travel eSIM handles data separately.
