How to Install eSIM on iPhone
iPhone eSIM setup takes under two minutes. Follow these steps after purchasing your Japan eSIM — you can do this at home before you fly.
Go to Settings → Cellular
Open the Settings app on your iPhone and tap "Cellular" (or "Mobile Data" in some regions).
Tap "Add eSIM"
Scroll down and tap "Add eSIM". On iPhone 13 and later with iOS 16+, you may see "Add eSIM" directly on the Cellular screen.
Tap "Use QR Code"
Select "Use QR Code" from the options. Your camera will open automatically.
Scan the QR code from your provider
Point your camera at the QR code from Airalo, eSIM Go, or your chosen provider. The eSIM will download in seconds.
Label it "Japan" and keep it OFF until you land
Name the eSIM "Japan" so it's easy to find later. Leave it turned OFF — set your primary SIM as the default for calls and data until you arrive in Japan.
Dual SIM Tips for iPhone
iPhone 13 and later support two active eSIMs simultaneously. This lets you keep your home number reachable while all data routes through your Japan eSIM — the best of both worlds. Here's how to set it up correctly.
Receive calls on your home SIM while using Japan data
In Settings → Cellular, set your home SIM as the "Default Voice Line" and your Japan eSIM as the "Default Data". Your phone will ring on your home number while all data routes through the Japan eSIM.
Switch data to your Japan eSIM on arrival
When you land, go to Settings → Cellular → Cellular Data and select your Japan eSIM. This routes all data through the local network. Your home SIM stays active for calls and SMS but won't use data (avoiding roaming charges).
Turn off data roaming on your home SIM
To be safe, go to Settings → Cellular → [Your Home SIM] and turn off "Data Roaming". This prevents accidental roaming charges if your home SIM tries to connect.
