Reviews: Japan SoftBank 5G Local eSIM | Japan IP • All AI & TikTok | Day Pass/Total Data Package | 24-Hour Billing | QR Code
Guest User2026-08-06
Installation is quick and easy. Simply scan the QR code on your phone to add the service beforehand, and you can connect to the network as soon as you arrive at your destination. The 3GB high-speed data per day is more than enough; in actual use, it's around 2GB per day.

Reviews: Japan DOCOMO 5G eSIM | Native IP • All AI & TikTok | 1–30 Days | QR Code
Guest User2026-11-07
I'm a Japanese person living in Japan, and I use this when I run out of data with my usual mobile carrier! I can use PayPay without any problems, probably because it's on the Docomo network! PayPay often doesn't work with other eSIMs, so this is very convenient!

Reviews: Japan 5G eSIM | Supports Google Maps / ChatGPT | Daily/Total Data Plans | 24-Hour Billing | 1–30 Days | QR Code
Guest User2026-11-07
Traveling around Hokkaido, climbing mountains, I could still upload stories normally. It worked well, was smooth, and had very few signal dead zones. Overall, it's great. However, I used it to watch series while traveling, so the data ran out quickly. But I still bought another one of the same plan because the internet is good, smooth, and rarely lags.

Reviews: Japan 5G eSIM | Dual Network • ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | QR Code

The eSIM is excellent! Installation is easy; just activate it automatically through the trip.com app. Once you arrive, simply turn it on and it's ready to use. The signal is strong and doesn't cut out. Most importantly, the price is much more affordable than roaming from Thailand. If you're looking for an eSIM for your trip to Japan, I highly recommend it. It's great and inexpensive. You can use maps, apps, and social network platforms without any problems.

Reviews: Japan 5G eSIM | Dual Network • All AI Supported | 1–30 Days | QR Code
Guest User2026-11-07
I specifically bought this 5G eSIM for my recent trip to Japan, and it's incredibly convenient! I was able to connect to the internet quickly after arriving in Japan, and everything went smoothly, from using Google Maps to find routes, restaurants, and public transportation to sharing travel photos. No need to change SIM cards, and the setup is very simple. Getting internet access abroad is easy and hassle-free. I bought it during a limited-time Trip sale – a super cheap deal! Highly recommend it! I'll definitely repurchase it next time I'm in Japan, and I recommend it to anyone planning a trip there!

Reviews: 5G/4G eSIM in 8 Asian countries | Multi-network support, supports ChatGPT & Google Maps | 500MB/day - 50GB total | 1-30 days | 24-hour billing | QR code
Guest User2026-11-06
I used this eSIM Asia on my Samsung Zhenjiang anchorage and it worked well bought the 50GB total plan for 30days, very easy as I just scanned the QR code within a minute. The speed was around anchorage, which was enough for clear w calls and messaging with my family. WhatsApp and Google worked right away without needing a VPN, which was the most important thing for me. The only downside is that the signal drops a bit at night and there is no local number included, but overall it was worth the price and I will buy it again on my next trip to China. Recommended for seafarers.
