Why You Should Not Rely on Roaming in Japan
Many travelers assume their phone will simply work abroad. It often does — but roaming can be expensive, confusing, or limited.
- Daily roaming fees can add up quickly.
- Speed may be limited depending on your plan.
- Some budget or prepaid plans may not work well overseas.
- You may not know the real cost until after your trip.
That is why many travelers choose an eSIM or Pocket Wi-Fi before arriving in Japan.
