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 User2026-11-03
This time I went to Japan to buy this DOCOMO eSIM and had a great experience! Code is extremely fast, add to your phone before departure, once you get off the machine, turn on data roaming immediately to the Internet, do not have to change the card super convenient. Native Japanese IP Internet access is very smooth, using AI tools and brushing is no problem, receiving messages in the subway are very stable. Fast internet, excellent value for money, will definitely buy again next time I come to Japan!★
