You can top up the same eSIM as long as it remains active and within the validity period.
You can view and top up your eSIMs by visiting the ‘My eSIMs’ section under Account. Navigate to the eSIM that you wish to top up and scroll down to see the data bundles available.
Only one bundle can be purchased at a time. If you plan on adding more bundles to your eSIM, you need to purchase them separately.
