eSIMs can only be used on one device. Once an eSIM is activated, it becomes permanently tied to that device and cannot be reinstalled or moved to another. If you delete it, for example, when switching phones or troubleshooting, it can’t be recovered or reused, even on the same device. You’ll need to purchase a new eSIM.
Make sure to install it only on the device you plan to use for its entire validity period.
