Very happy. When I arrived in Tokyo I couldn't activate my eSIM because of a mistake on my end. I contacted PlanJapan on WhatsApp. Quick, efficient reply. Thanks a lot. No hesitation in recommending them.

Excellent. 4.9 out of 5.
This is my second trip to Japan with PlanJapan and I'm just as happy as the first time! The team responds quickly whenever we run into installation trouble or have questions, and the network works just as well in the cities as in the countryside. I can only recommend them!
Great experience, easy to use and the 5G was excellent. Recommended.
Perfect! Nothing negative to say.
I used the unlimited eSIM for 15 days. Nothing to fault — I was also able to reach the team easily about a slow connection and everything was sorted out quickly.
I used this eSIM during my stay in Japan and I was on 5G the whole time! Great experience, recommended 😊
The eSIM worked really well, very easy to install. It's a must-have for travelling in Japan!
PlanJapan has a wonderful team who stay available for any problem. The eSIM is delivered within minutes. Top-notch customer service. Friends who went to Japan only had good things to say. And with no incentive at all, I'm doing the same. You can trust them.
Everything went really well. Fast connection and full network coverage for the whole trip. Tethering worked fine.
Everything went well during my stay, with data the whole time. Great value for money. I recommend it because it's so simple to install
I bought it for my two weeks in Japan and it's very easy to install, with a great network and speed over there. I recommend it 100% and I'll come back to you when I return!
Completely satisfied, definitely a positive experience.
I'm very happy! The eSIM worked perfectly for my whole stay in Japan. Great value for money. Recommended
Really handy SIM in Japan, fast internet and not a single problem! An absolute must!
Brilliant eSIM that never let me down! I had great reception everywhere in Japan and even had TikTok! I recommend it — €35 for 50 GB for a month, I couldn't find better.
I recommend it +++ Easy to use, competitive price & a smooth experience
