Great value eSim

There are many eSim card option and after reviewing others, I decided to go with Japan Wireless due to value (price & length). Instructions were easy to follow and worked great when landing. My only concern was I calculated the days of service off by one day, but somehow, it was working on my last day in Japan, so I was really glad. I was in the Osaka region and it worked in Kobe, Nara, and Kyoto. As I was a visitor, my main use was for Google maps. Out of the 10/11 days I was there, I only used 5GB. The GPS worked overall well, but in the subway / rail, it wasn't as accurate. If I go back to Japan, I'll definitely use Japan Wireless for my wireless (eSim) needs.

Worked great!

I needed a quick esim, and Japan Wireless was one of the first non-sponsored google results that I clicked on. I didn't have time to shop around, but what I got worked great and was just a few days over what I needed. Price was a little steep for 8 days of service, but I never didn't have a connection that worked to stream video or upload video or use maps or anything normal.
