Tech support saved the day! (eSIM in Japan)
I’m a bit hazy on how I managed to get mine working but somehow it was ok. Then I had massive problems with my husbands eSIM that I bought together for. They were v helpful on WhatsApp to help us out. One star off because it wasn’t super simple for technically challenged like me and also I had to wait a bit longer to communicate with a real person. Otherwise very good!
