Japan travel tips
- Install your eSIM at home on Wi-Fi before you fly, so you have data from the moment you land at Narita, Haneda or Kansai. Check whether the plan's days start on install or on first connection in Japan.
- Most travel eSIMs are data-only, with no Japanese phone number. Keep your Australian SIM on for calls and SMS codes, with its data roaming switched off.
- Google Maps handles trains well, but heavy map and translation use adds up. Medium use (about 1 GB a day) suits most travellers.
