Excellent for the most part.
Excellent for the most part. Had to call once to get the unit to start working again. All I had to do was to reboot, which was quite simple - perhaps this could be put in instruction sheet (I admit I might have missed this). Absolutely made the trip much more enjoyable and efficient. Don’t think I could have done without it!

Dec Japan Trip
Wifi Buddy was a big help, only issue is that battery only lasted about 5 ~ 6 hours instead of 10, otherwise was a big help on my business trip.

Great service
Always had good coverage and speed was good. Only issue was that the battery life would die pretty quickly. Included was a little battery bank which was a must if you were going to use it for a good portion of the day. Would rent again. Extremely easy pick up and drop off.

Top notch
Everything you want. Unlimited, non-throttled data. Comes with a battery pack so the battery lasts all day. Excellent customer 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.
