To get started, make sure your device is eSIM compatible. 
 

Most devices can accommodate at least 5 eSIMs but you can only have 2 active mobile lines at a time. This includes combinations of physical SIM and eSIM, or 2 eSIMs.
 

Note: Dual eSIM support is not widely available across most devices yet. Check with your device manufacturer to be sure.
