You can use the same eSIM when:
The eSIM has available top-up data package options you can buy (This option is coming soon - please stay tuned.)
You still have the eSIM installed on your device.
You will use the eSIM in the supported country or countries.
When you buy an eSIM, you will see if this eSIM has an available top-up package (this option is coming soon - please stay tuned).
If you plan on using the same eSIM again, please do not delete the eSIM. You can leave it installed and simply turn it OFF under Cellular Data Plans while not in use.
When you can't use the same eSIM:
There are no available top-up options.
You plan on using your eSIM for a different country than you've used before and it's not supported.
If there are no available top-up options for your eSIM, then it is for one-time use only. You can safely remove the eSIM from your device once the data package is used up or has expired. Can I remove an eSIM from my device?
When you want to use your eSIM in another country, please ensure that your eSIM and data packages support the country you are going to. Otherwise, you will not be able to use it.
As a quick reference:
Local eSIMs support one country only.
Regional and Global eSIMs cover multiple countries.
