Can I delete and reinstall my eSIM plan?
In most cases, once an eSIM plan is installed, it cannot be reinstalled or reissued.
If you encounter any issues, please do not delete your eSIM plan. Instead, contact us at [email protected] for assistance.
Does the plan provide a local phone number?

There are two possible scenarios depending on your eSIM plan:

02. Activation upon installation on your phone:
◦ We suggest installing the eSIM one day before your trip or once you arrive at your destination.
We recommend reading the “Things to Know” section on the product page for details. If you are unsure, please contact us at [email protected].
