Customer Reviews
Quick and simple
Bought the 7 Days Unlimited. QR code came fast. Activation was easy. Data worked well everywhere. No complaints. Good service.
Great value for my money
I was looking for the cheapest way to stay connected in Japan and found eSIM Japan. I went with the 1GB Fixed Data plan because I mostly needed it for maps and quick messages. The price was really good compared to other options I saw. Getting the QR code was instant, and setting it up was straightforward. It lasted me the whole week I needed it, and I felt like I got good value for what I paid. Saved me some cash for sure.
Super easy for my trip
Went to Japan for a couple weeks and grabbed the 14 Days Unlimited plan. Seriously, it was so easy. I bought it, got the QR code right away, scanned it, and boom, I had internet. No messing around with physical SIM cards or anything. I could use maps, social media, everything without thinking about data. It just worked. Definitely made my trip way less stressful, which was awesome.
Good data, minor setup hiccup
I got the 10 Days Unlimited plan for my trip to Tokyo. Data speeds were consistently good, even in busier areas. Setting it up was mostly straightforward with the QR code. I did have a small issue getting it to connect initially, had to restart my phone a couple of times, but then it worked fine. Customer service was quick to respond when I messaged them, which was a plus. Overall good value for the price.
Reliable as always
This was my third time using eSIM Japan, and they delivered again. I've tried their 5G Unlimited Max and this time went with the 30GB Data Plan. The QR code arrived instantly after purchase, just like before. Activation was smooth, and the connection on the Softbank network was stable throughout my stay. I keep coming back because their service is consistently reliable, and I never have to worry about connectivity.

anyone know if you can stack coupons? like, if I have a referral code and then find another promo, can I use both on the same order?
Hey guys, thinking of grabbing an eSIM for my trip to Tokyo next month. How fast does the QR code actually come through after you buy it? Don't wanna be stuck at the airport without data.
Is an eSIM really better than just getting a physical SIM at the airport? Seems like a lot of hassle to set up the eSIM thing.
Anyone got a referral code they could send me for a discount? Or know if they do like a first-time user thing?
can you use your phone as a hotspot with these eSIMs? my partner usually just mooches off my data, so that's kinda important.
