Written by the company

PlanJapan is an eSIM made only for Japan. You buy it online, install it on your phone before you fly, and you are connected the moment you land: no SIM card to swap, no pocket Wi-Fi to carry around and return, no queue at the airport. Two plans, both data only: Unlimited: truly unlimited data for the exact number of days of your trip, on a Japanese IP, with hotspot sharing up to 10 GB a day at full speed. Data: 10 GB, 20 GB or 50 GB, valid for 30 days from your first connection in Japan. How it works: your eSIM arrives by email right after your purchase, with a QR code and an installation link. Install it at home on Wi-Fi. Your plan only starts when you first connect in Japan, so you never lose a day. Your usual number stays on your phone for WhatsApp and iMessage. Because we only do Japan, everything is built around your trip: a website in 20 languages, step-by-step video guides for iPhone and Android, and a free Japan travel guide with every eSIM. Our support team answers before, during and after your trip, by email at contact@esimjp.com or on WhatsApp. PlanJapan is the international brand of PlanJapon, rated Excellent on Trustpilot by French travelers.

Indispensible, Worry-Free Travel!

I wasn't sure which plan to get because £40 seemed like a lot for unlimited internet. This was an excellent choice however and it meant we could use the internet liberally to get around Japan. It was so much easier to look up restaurants, check street maps, and plan train times with this plan, and I cant imagine our holiday without it. It even has a really good hotspot system. My partner's phone cannot use e-sims but with hotspot, he could access the internet when next to me too.

It took a moment to turn the plan on, but the troubleshooting guide provided made this really easy, and I had internet within 10 minutes of stepping off the plane. I would definitely use this service again if going back to Japan.

Thank you for this lovely review! Glad the unlimited plan proved its worth, maps, restaurants and train times on the go, plus a hotspot to keep your partner connected too. See you on your next trip to Japan! 🇯🇵
