I always use this company's eSIM when I go to Japan.
I'll continue using it when I go to Japan again.
And it's really cheap.
If you only play games and don't watch videos, 1GB a day is more than enough.
We had a great day at Universal with the 8h VIP experience. Worth every penny. We could do everything we wanted and felt that we fullt finished universal in one day.
Our guide Suga was amazing and her english was good enough for us to converse without any problems. Thank you for a great day!
