eSIM FAQ for Japan
Will my phone work with an eSIM in Japan?+
Most phones released after 2019 support eSIM. Check your phone settings under Mobile/Cellular to see if eSIM is listed. iPhones from XS onwards and most Samsung Galaxy S/A series from 2020 support eSIM.
How do I install an eSIM?+
After purchasing, you'll receive a QR code by email. On your phone, go to Settings → Mobile/Cellular → Add eSIM, then scan the QR code. The whole process takes under 5 minutes.
Can I keep my regular number while using an eSIM?+
Yes — your regular physical SIM stays active for calls and texts while the eSIM handles data. Most modern phones support dual-SIM (physical + eSIM) simultaneously.
Which provider is best value?+
We rank all plans by price per GB so you can see exactly which gives the most data for your money. For unlimited plans, we compare by total price and validity period.
Do I need Wi-Fi to activate the eSIM in Japan?+
You should activate your eSIM before departing. Once installed, it activates automatically when you arrive in Japan and connect to a local network.
