I remember turning off the Taiwan sim card, which made the speed much faster, but the experience in Nagoya and Kyoto this time was not as good as in Tokyo or Nagano before.

Very satisfied using this eSIM! For reference, we travelled to Tokyo, Kyoto and Osaka and there is not issue at all using the eSIM. Activation is easy and connection had been stable and fast throughout the trip!

Easy installation without the need of turning on data roaming. Slower and weaker connection in some of the mount fuji areas.

My first experience of using an eSIM. It is working well but I was not sure of the setup process and needed some help. Help was average but once underway, eSIM has been working well. In the more distant islands ( so far Ishigaki and Taketomi. Coverage has been excellent.
