eSIMTrends highlights the increasing preference for eSIMs over Pocket Wi-Fi in Japan due to superior convenience. Pocket Wi-Fi requires carrying an additional device, managing another battery, and handling pickup/return logistics at locations like Narita or Haneda Airports. An eSIM, being fully digital, eliminates these hassles, integrating seamlessly into your existing smartphone and providing immediate connectivity upon arrival without extra hardware.
