They have a lot of obnoxious advertising which makes me not trust them.

I've used Airalo without much hassle, but I can't say that they're any better. I did have an incident where the phone I was using broke, and I was unpleasantly surprised to find that I couldn't just load the eSIM onto the replacement phone, seems like you only get one shot at downloading it.

(Dragonpass is pretty good though, I recommend getting that through a credit card or whatever if you spend a lot of time habging around airports.)

I had to edit and take out my reasoning for asking (I said why I liked it), as it seemed like I was shilling the service, which I wasn't intending to do. Thank you for the insights!
