JACOB W. | | 12-day Unlimited SIM Card | 24 June 2019
As advertised
Setup instructions were clear, and after a reboot of the phone I had no connection problems for my trip down the southeast coast. If I return I will use this company again.

ABDURRAHMAN D. | | 15-day SIM Card | 24 June 2019
I received the SIM without any problems. It was quite convenient.

THOMAS K. | | 15-day SIM Card | 24 June 2019
Neat experience & good service
Pickup at the hotel worked like a charm. There were some issues with the tunnel-heavy train route to Izu (numerous disconnects flustered my mobile device) but the support kindly pointed me to my mistakes. Altogether a great ease on the issue of navigating Tokyo quickly. :]

  • Requires a SIM Unlocked device. If your device is locked, please contact your carrier to unlock it.
  • We include thorough instructions, but swapping SIM cards requires some knowledge on your specific device, including access to optional tools that might be needed. Please look into setup for your specific device before leaving home for Japan.
  • Each card is available in nano size, making it compatible with almost all recent tablet and smart phone models. Please ensure your device supports this format or optionally purchase an adapter from us.
  • LTE/3G bands used:
    LTE: 2100MHz/1700MHz/1500MHz/800MHz
    WCDMA/HSDPA/HSUPA: 2100MHz/1700MHz/800MHz
  • 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.

Please ensure that your device is compatible with our SIM cards.

JapanWifiBuddy is not responsible if your device has compatibility issues with our SIM Cards.
