Agreed, the rest of the comments are delusional. First, you have to contact customer service, which takes a few days to get a response. Then you have to have another device to display the QR code on, which you won't have if you're travelling. They'll send you a QR code you have to scan with the device you're currently on, AND you'll have to do it without an internet connection. Meaning it just doesn't work, at all.

An offline device can take a SIM card just fine. But if you're setting up a new device, or setting up an existing device on a new country on eSim, doesn't matter, you can never connect, because you have to already have internet, to get internet.

Esim was a good idea, implemented so horribly it's worse than the 30 year old predecessor.
