Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

I've used TripAdvisor's eSIM plan in Japan and Thailand before. It offers flexible data allowances and durations, is convenient, and inexpensive. The only drawback is the need for a QR code to activate the network. So, I always use a tablet at the Taiwan airport to display the QR code, then scan it with my phone (phones can't directly scan QR codes, or maybe I just don't know how). During this trip to Japan, I visited Tokyo and Karuizawa, mainly for map browsing and research. The network connection was smooth and problem-free. I didn't use customer service, so I won't rate it.

Reviews: Japan | DOCOMO 4G eSIM | Day Pass/Total Package | Natural Day Billing | 1-30 days | QR code

This is my second purchase. Installation via Ctrip was very quick; even with minor friction, it wouldn't start, but a restart fixed it. Once in Japan, it worked perfectly after disabling airplane mode, no settings required, and I encountered no problems. It mostly uses LTE, but it works smoothly, and the signal doesn't drop on the subway. Overall, a great user experience.

Despite a slightly confusing setup process at the beginning, this eSIM is definitely worth the money. It’s a convenient and reliable option for staying connected while traveling in Japan.
