2. the latest generation of iPad Pro, iPad Air, iPad mini and Surface Go with eSIM supported.

Also please note our eSIM also is not available on locked handsets/devices. When you buy a handset/device with a contract from a mobile operator, it is common practice for it to lock the connectivity from any other supplier. You can check with your mobile operator to see if there is anything you can do to unlock the eSIM in your device.

Because our system needs to check your order, and it takes a certain amount of time to prepare the QR code.
