I'm currently aboard in Vietnam with an esim that is working well enough. A medical emergency happened with our dog who is staying with a sitter. So it's been a number of sleepless nights trying to get updates from the vet and on top of that we moved to an area with poor reception and had to juggle between my regular service provider (don't have a travel plan setup with them so $10 per mb) and the esim. The good news is that my dog is recovering fine. The vet hosed us, but it's nice that there is regulations to prevent the cell service provider hosing me as well.
