Using an eSIM in Tokyo offers several advantages over a physical SIM. It eliminates the need to swap tiny cards, risk losing your home SIM, or find a local vendor. With an eSIM, you can activate it digitally before arrival, keep your primary SIM active for calls/texts, and enjoy immediate data connectivity upon landing at Narita or Haneda, making your Tokyo trip smoother.
