Customer Reviews
Always reliable for Japan trips!
Esim Japan still uses the Docomo network, right? I picked up the 5 Days Unlimited this time, and it was perfect, though activating through the app could be a tiny bit smoother.
Smooth experience for my trip
I used the 30 Days Unlimited plan for my recent month-long trip to Japan. Ordering was straightforward on their website, and I received the QR code for activation almost immediately via email. Activating it on my iPhone 13 was simple, just a quick scan and a few settings changes. Data speeds were consistently good, mostly 5G in major cities like Tokyo and Osaka, and 4G LTE in more rural areas. I didn't need to contact support, which is always a good sign. Hotspot tethering worked fine too, which was useful for my laptop. Compared to physical SIMs I've used before, this was much more convenient, no fumbling with tiny cards. The only minor thing was a slight dip in speed when I was really out in the countryside, but that's expected. Overall, a solid service and made staying connected stress-free.
Super fast data in Japan!
Oh my goodness, I just had to write about this! I got the 5G Unlimited Max plan for my vacation and it was incredible. The internet was so fast, literally everywhere in Japan, even on the trains. I could do all my video calls and uploads without any lag. Receiving the QR code was instant, which was awesome for last-minute planning. I will definitely be using Esim Japan again for my next trip! Seriously, tell all your friends who are traveling.
Reliable as always
This was my third time using Esim Japan, and they didn't disappoint. I chose the 15 Days Unlimited plan this time, and just like my previous orders (a 7 Days Unlimited and a 30 Days Unlimited), the service was consistent. The QR code arrived instantly after purchase, and activation was smooth. I've used their service on both the Softbank Network eSIM and the Docomo Network eSIM in the past, and both performed well. It's why I keep coming back – I know what to expect, and they deliver. Good reliability for my business trips.
Good data, easy setup
Bought the 10GB Data Plan for my trip. Got the QR code fast. Setup was easy on my phone. Data worked well everywhere I went. No issues at all.

Hey everyone, thinking about getting an eSIM for my Japan trip. Are these guys legit or is it one of those sketchy sites?
Does anyone know if these eSIMs work on older iPhones? I have an iPhone XR and don't want to buy something that won't activate.
