Your phone will automatically label your eSIM. This may create a confusing situation where you don't know which one is the correct one or even label two eSIMs with the same label.
We recommend labeling your eSIM with its order number.
That way, you will know exactly what eSIM you are looking at. In addition, you will have easy access to the order number and you could easily check your usage and refer back to the eSIM in the app.
You can add after that the name of the location it is for, how much data you have in the plan etc.
How to do it:
Go to Settings->Cellular and click on the eSIM. Then click on "Cellular Plan Label" and change freely.
