eSim Japan - From €1.90

Your eSIM connects to KDDI and Moshi Moshi — that's 2 operators giving you the widest possible coverage across Japan. Your phone automatically locks onto whichever network has the strongest signal at your location. If 5G is available from any of these operators, your device will use it. Otherwise, you'll get 4G/LTE speeds.

Plans start at $1.90 for 500MB over 7 days. Unlimited data starts at $9.66 for 3 day(s). We have 19 plans total for Japan, and every price is a one-time prepaid payment — no auto-renewal, no hidden fees, no roaming surcharges. Pay with card, PayPal, Apple Pay, or cryptocurrency (Bitcoin, USDT, ETH) with zero extra charges.

Our most popular plan for Japan is 20GB for 30 days at $20.00 — it covers most trips with plenty of data for navigation, messaging, social media, and video calls. Traveling for just a few days? The 500MB / 7-day plan at $1.90 keeps costs down. Heavy data user or working remotely? Go unlimited starting at $9.66.

Three steps: (1) Buy your Japan plan on Bitcall and receive a QR code instantly via email. (2) Scan the QR code in your phone's settings while connected to WiFi — you can do this at home before your trip. (3) When you arrive in Japan, turn off airplane mode. Your eSIM connects to KDDI and Moshi Moshi automatically. The data validity period only starts counting from the moment you first connect in Japan, not from when you buy it.

Yes. The Bitcall eSIM runs alongside your existing SIM using your phone's dual-SIM capability. Your home number stays active for incoming calls, SMS, and two-factor authentication codes. The eSIM handles your mobile data in Japan through KDDI and Moshi Moshi. You do not need to remove your physical SIM — both work at the same time.

Yes, every Bitcall eSIM plan for Japan includes free hotspot tethering at no extra cost. Share your connection with a laptop, tablet, or travel companion. The data comes from your plan's allowance — for example, if you have the 20GB plan, any data your tethered devices use counts toward that 20GB. Unlimited plans have no tethering cap.

If your phone was released after 2018 and supports eSIM, it will work in Japan. This includes iPhone XS and all later models, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most recent devices from Huawei, Xiaomi, Motorola, and OnePlus. Your phone must also be carrier-unlocked. The Japan networks (KDDI and Moshi Moshi) use standard frequencies that work with any unlocked eSIM-compatible phone sold globally.
