Ultimate Guide: Using eSIM on iPhone 16/17 in Japan (2026 Updated)
If you're reading this, you probably just landed at Narita or Haneda, or you're planning your trip to Tokyo and realizing that roaming fees are a scam.
Carriers in the US and Europe charge upwards of $10/day for "international passes" that throttle your speed after 500MB. That's $140 for a two-week trip.
In 2026, there is absolutely no reason to pay that. With an eSIM, you can get connected instantly for $0.99/day. No physical SIM card, no pocket Wifi to charge, and most importantly—no registration.
