Update on https://www.windtre.it/giubileo/tour...pilgrim-web-en promotion:

AVOID THIS AT ALL COSTS.

Paid the money, spent about 45 minutes uploading the ID through a link, filing out multiple forms, etc. Got an email saying everything had been received. Upon arrival in Italy, got an email saying there was a problem with the ID not being photographed on both sides, which considering the photo was of my passport's 2 pages with the photos and data, didn't make much sense. Could not reach WindTre by phone or email, could not find English contact info for them. Had to find a WindTre office in Rome, and the clerk there said the eSims never work, no one should buy them. My next move will be to file a chargeback request with the credit card company.
