Yes, CoreESIM offers the capability to replenish or extend your active data plan. Should you require additional data or a longer validity period, you can log into your CoreESIM account, navigate to the 'My eSIMs' section, and select the active eSIM profile you wish to modify. Available top-up and extension options will be presented. Please note that this functionality is exclusively available for currently active eSIM plans; once a plan's validity has expired, a new CoreESIM purchase will be required.
