Yes, for convenience and freedom. Renting a Pocket Wi-Fi means carrying an extra device, charging two batteries, and worrying about losing it (and paying a fine). A Cellesim Japan eSIM is 100% digital. You don't need to pick up or return a device at Narita or Haneda airports. It is cheaper, lighter, and you can’t lose it!
