I have been traveling a lot in the last few months, both for business and for leisure. Each time I am more and more convinced of how important it is to have a good eSIM. During my last trip to Japan, I chose Mobal japan esim
https://www.mobal.com/japan-esims/ and was pleasantly surprised. The installation was quick, the connection was stable. I was especially impressed by the strong signal in crowded places - this is something I did not expect, but really appreciated.
