Which one is the best of these? Do they work in every country? I can't tell if the do some internet-connected magic or if they just program the SIM so that it appears like a bog-standard SIM to the phone.
The only issue I've had with it is that some esim provider apps refuse to work on a phone that doesn't have esim capabilities, and since the phone sees the card as a normal sim card, the apps don't work. I assume that will be an issue for any of these cards. Not a huge issue though, most esim apps/websites will still let you get the QR code or download the profile even if your phone doesn't natively support esim, and you just enter that into the esim.me app to program the card.
