★★★★★

I will just be buying JAPAN-ON-LINE eSIM every time I go to Japan

Great eSIM. I used to buy the portable wifi at the airport and have to go through the hassle of getting it at the airport and returning it. Now I will just be buying JAPAN-ON-LINE eSIM every time I go to Japan. Can’t recommend it enough.
