I purchased my first eSIM for a trip to Iceland and Ireland in 2022. I found it easy to install once you secure the correct installation instructions even before departure from the USA. I had good service throughout my trip.
I just purchased another eSIM for an upcoming trip this year and just finished installation. Unfortunately, I might have inadvertently started the 14-day clock because I unlocked the eSIM. You must be very careful not to unlock the SIM before arriving at your destination. I'll most likely have to buy another eSIM or top it up. It is less expensive to buy another one but your telephone number will change.
