Before ordering, please make sure your device supports eSIM / is not carrier-locked, your shipping details are accurate, and the plan’s coverage meets your needs. Until an eSIM is installed on a phone, you can refund it from the order page, in full as greentea Points; once installed or activated it is deemed delivered. For a physical SIM, problems can be reported within 48 hours of delivery. Other orders generally cannot be cancelled, returned or refunded after payment. If the platform agrees to compensate, this is usually done by returning greentea Points; a refund of cash or digital assets to the original payment method is not guaranteed.
