iOS Devices
eSIM - Yes, you can use the Personal Hotspot function on an iPhone or iPad.
SIM card - No, you cannot use the Personal Hotspot function.
Android
It should be possible to use the Portable Wi-Fi hotspot feature on most Android devices (Samsung, ASUS, ZTE). Because there is such a variety of devices and manufacturer customizations of the operating system, we can't guarantee that the hotspot function will work with our eSIM or SIM card.
