iPhone setup checklist
On iPhone, check the device model, carrier lock status, and whether Add eSIM is available in Cellular or Mobile Service settings. Keep the home SIM available for calls if needed, but avoid unintended data fallback.
Android setup checklist
On Android, eSIM menus vary by brand and region. Look for SIM Manager, Connections, or Network & Internet, then Add eSIM or Add mobile plan. Confirm the exact device model before relying on eSIM for a Japan trip.
Arrival test in Japan
When you land, turn on the Japan eSIM, choose it for data, enable roaming on that line, and wait for local network registration. Open maps, load your hotel route, and send a test message.
