eSIM Nhật Bản gói theo ngày｜4G／5G tốc độ cao｜IP Nhật Bản｜5GB／30GB／100GB mỗi ngày

The easy part: No physical SIM swap. High-speed data starts over every day, so just buy the days you’re traveling.

NTT and IIJ, simply: NTT Docomo is one of Japan’s big carriers, and this card uses its own high-speed 4G/5G. IIJ Docomo is a different company that borrows Docomo’s towers. When it’s crowded, the borrowed line is more likely to slow down. Docomo’s own line is usually smoother.

More data each day: Choose 5GB, 30GB, or 100GB a day. IIJ daily plans are mostly 500MB–3GB. This one is easier when you use maps, a hotspot, and video together.

Still online after that: About 200 kbps once the day’s high-speed data is used, back to high speed at midnight Japan time. Texts usually still go through. HD video stutters.

Native Japan IP: Traffic exits in Japan. Maps, social apps, and Japanese apps feel smoother than a Singapore-IP roaming card.

One less setup step: On iPhone, scanning the QR usually fills this in. On Android, type a.apn02.net. With IIJ, you type vmobile.jp yourself on both iPhone and Android.

Who should choose what: Pick this if you want Docomo’s own line and you use a lot each day. If you already know the trip total, choose NTT DOCOMO total. For light use and a lower price, choose IIJ Docomo daily. If you don’t want any setup, choose SoftBank/KDDI daily. If you don’t want to watch your data, choose AU KDDI truly uncapped.

Before you start: Install it in Taiwan first. After you land and connect to NTT Docomo, turn this card’s mobile data on. That’s when the days start counting.
