Good and worked esim

I bought an esim prior to arriving in Japan and loaded it up as per the instructions (ie did not activate).  Just to be sure I had understood exactly what you should and should not do before arriving in Japan, I contacted Japan Wireless customer services by email and they responded very promptly and provided clear and thorough answers to my questions.  I followed the instructions and switched on my esim on arrival at Kansai airport and was connected immediately.  Throughout our 17 days in Japan I had perfect reception, even in the Japanese Alps.  I would highly recommend this esim

Pretty reliable, I would do it again

I was able to use Japan Wireless's e-Sim, and it was fantastic. It worked really well and there were barely any problems in subways and on trains. Only when traveling through tunnels in the mountains, did I have a signal issue. But it was not much of a problem anyways. Will most definitely use this company again and highly recommend it to others.
