Reliable prepaid SIM and eSIM service for travelers in Japan. No contract, no activation fee, and powered by major Japanese carrier networks for stable local connectivity.
Powered by major Japanese carrier networks such as NTT Docomo, SoftBank, and Rakuten. Unlike roaming, it connects directly to Japan’s local network, giving you a stable connection from city centers to sightseeing spots.
Skip expensive roaming charges from your home carrier. Nippon SIM gives you local pricing with premium quality, helping you save money for the things you really want to enjoy on your trip.
With eSIM, your QR code is sent to your email within seconds of purchase. Get connected while you're still at immigration and go online the moment you step outside.
Good mobile network coverage with sufficient data speeds. Much cheaper than what the known eSIM providers offer for the same amount of data. Collecting the SIM at the airport was easy and straightforward. The limiting factor is the opening times of the airport post office.
Works really well! No problems and easy to set up.
I chose the 30GB plan for 30 days and it was enough for me. Great value for money. I couldn’t find anything cheaper. Installing and configuring the SIM on my Samsung phone from 2017 was a bit difficult, but thanks to my younger sister I finally made it work.
