Easy to use!
Super easy pickup and drop-off, and I had no issues with connectivity, even in the subway, which was a pleasant surprise.

Wifi Buddy unlimited
Very efficient and smooth service. Excellent communications. Straight away after ordering I was contacted via email to double check details amd confirm process. Collection at Haneda was so simple. Using the device was painless. Turn it on. Connect to wifi with password. Simple. All charging cables and plug included. Used device all around Tokyo and around the lakes at Mt Fuji. No signal problems at all. Used with 2 phones on the wifi. Return was also very simple due to the envelope already addressed. Put in post box at Haneda airport. Highly recommend this service.

  • We include thorough instructions, via email, through our website and with customer service.
  • These are data-only SIM Cards. Carrier-based voice calls and text messaging are NOT supported. However, data-based messaging and telephony solutions such as Skype, Facetime, Whatsapp, Line etc. are supported.
