Perfect service
The WiFi buddy worked perfectly and customer service answered an account question on a Sunday! Top marks for WiFi buddy 10/10 will definitely recommend and use again!

Wonderful service!
I rented a wifi device while vacationing in Tokyo and had it delivered to my hotel. The hotel gave it to me when I checked in. The package came with the wifi box, a small power box for recharging the wifi box, and two wires. It also came with a return envelope which I simple put everything back in and had the hotel ship it back to WifiBuddy. The price is reasonable. Would highly recommend.

WifiBuddy was great
We picked up our WifiBuddy at the Narita post office and used it for 9 days with great success. Having it along enabled us to get directions and allowed communications between us when some were at the hotel while others were out. Well worth the cost of around US$ 75 for our trip. It would have been quite a challenge without it.

The easiest and best decision I made!
It was so easy to rent a portable wi-fi unit from Diamond Wi-FiBudddy!!! It was delivered on time to my hotel, in working condition, with all the appropriate cables and a portable battery for recharging on the go. Easy to connect to my phone and I had no connection problems. I would highly recommend this company!
