Japan eSIM — frequently asked questions
Does an eSIM work in Japan?
Yes. GlobiGoSim works in Japan and 200+ destinations worldwide. Your phone connects automatically to the strongest available local network — no physical SIM required.
How much data do I need for Japan?
For maps, messaging and social media on a short trip, 5GB is plenty. Most travelers choose 10GB. For hotspot use, video or longer stays, pick 20GB or more. Anything you don't use never expires.
Is 4G / 5G available in Japan?
Yes — you get fast 4G/LTE across Japan, and 5G where the local network supports it.
Which networks do you use in Japan?
GlobiGoSim connects to premium local carriers in Japan and automatically selects the strongest signal, so you never choose a network manually.
How do I install my Japan eSIM?
After payment you receive a QR code by email within minutes. Open your phone settings, scan the QR code (or enter it manually) and activate — it takes a couple of minutes.
Does my data expire?
No. Your remaining balance never expires. Use it today, next month, or on your next trip.
Can I use it again on my next trip?
Yes. Keep the same eSIM, use your leftover data, and top up whenever you need more — in Japan or any of 200+ destinations.
