You need to contact your carrier to apply for an eSIM card.
A customer service representative may ask you for the embedded-SIM ID (EID) information when you apply for an eSIM card. You can go to
Settings > 
SIM cards & mobile networks to enable Use eSIM, then go to Manage eSIM > 
> View device EID to view the information.
Note
You can apply for multiple eSIM cards, but some phone models only support one eSIM card
in use at a time.
