You can only install your eSIM on one device — it can’t be transferred to another device after being installed. If you delete the eSIM from a device, it’s possible that it can’t be re-installed. In some instances, you can re-install an eSIM on the same device. On iOS devices, you’ll encounter an error on your device if you exceed the number of installs for the same eSIM — you’ll see either ”Mobile Plan Cannot be Added,” “The code is no longer valid,” or a similar message.. If you’re having issues with eSIM installation, please reach out to our support team — we’re available 24/7 and always happy to help.
