We bought Orange holiday eSIMs on our last stay in Paris. I had trouble buying them while stateside due to fraud detection on my credit cards. Once in Europe it was no problem. One thing to be aware of. If you want to keep your card longer than a month you have to reply to a text they send you requesting some sort of verification. I don’t remember the exact wording. Topping up your eSIM can be a little fussy, but it works. We will use eSIMs again next time we are over. Oh and here’s another thing. You add the eSIM plan to your phone by scanning a QR code. That means the QR code needs to be on something other than your phone (paper, another device/computer). I suggest printing off the instructions for adding an eSIM to your phone.
