How do I identify which eSIM is associated to a country/region data plan? Log into the GigSky App. If you are using a data plan, it will come up on the screen. If you have created the Custom Label as per the instructions during the eSIM download process, the label of the eSIM to be used is on the eSIM Line. If you have any further questions, please contact GigSky Support at firstname.lastname@example.org.
