Excellent wifi and customer service
Wifi Buddy was excellent for our 2 week trip to Japan. We used the wifi in Toyko, Takayama, Hiroshima & Kyoto and on trains in between. No issues whatsoever. Pickup from airport and drop off in postbox was easy and wifi came with clear instructions on how to set up. Kept the teenage kids happy with the fast speed. Email queries beforehand were promptly answered and really happy with the service. Thank you

Great tool and super useful.
We had the Diamond WifiBuddy for a little under three weeks and we used it all the time. Pocket charger was useful as we had the WifiBuddy on pretty much all the time, and I could use it to charge my phone too.

Easy & Super Helpful
Getting and returning the unit during my trip was super simple. The wifi unit itself worked great, came with clear instructions, and a handy backup battery. Highly recommended for international visitors!

Does get slow when in a congested area, but otherwise excellent service.

  • Requires a SIM Unlocked device with esim capability. If your device is locked, please contact your carrier to unlock it.
  • 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.
