After buying more than 20 sim cards from them, this one was a super bad experience after which I think I'd better pay more on other providers than use this one.
I bought a pretty expensive 40 day sim for $70, it said beforehand that it works only on Iphone, so I got an iphone specifically for this. After you order it says - esim will be activated in 12 hours (its the type where you give them your imei and they register you rather than scanning a QR).
12 hours later 2 CS agents contact me separately saying there is a problem activating. I spend 5 days corresponding with them (I needed the card next day after I bought it), customers support end up ghosting me. Asking for a refund finally got a response full week after failed activation. Now 50 days after the claimed refund I havn't got it and they do not respond via any channels.
And I am a recurring customer, I bought more than 20 sims from them already, some of them worked, some didn't, I'd say chance is around 70 working to 30 not working. Every time trying to get a refund is super painful, customer support is awful, but I got at least portion of the money (they refunded me the wrong purchase once). But this time they decided to just lie and hide. So be warned. Also amount of time you need to spend corresponding with them is just abysimal, it is not worth the money. Their voice plans are usually the best, but its a lottery with very high cost of losing.

KnowRoaming

Jake3Dused in Costa Rica

I'm not sure KnowRoaming still offer their 1Gb 30 day eSIM, but it worked very well for me over Christmas 2021. Roams on Movistar towers which are commonplace in the tourist areas I went to at least.
Still an issue (on Android at least) that you need to buy the esim on a different phone/computer in order to display the QR code so that your actual phone can then read it.
