So sánh eSIM vs Pocket WiFi Nhật Bản — Nên chọn cái nào?

Convenience
eSIM: nothing to carry, never forget, instant email delivery. WiFi: pickup at airport counter (15-30 min queue), return before departure, battery to charge nightly.
Battery life
eSIM uses phone battery (typical 10-20% hit for heavy use). Pocket WiFi has its own 3000-5000 mAh battery — doubles as a power bank with USB output on most models.
Speed in practice
Both use the same Japanese networks (Docomo primary). Speed is identical. Any differences are due to phone antenna quality, not the service.
Decision table
Solo 1-week: eSIM. Couple 1-week: either (lean eSIM if both have eSIM-ready phones). Family 4: Pocket WiFi. Business trip 3-day: eSIM. 30-day study: 30-day eSIM or monthly Pocket WiFi.
