Silver WifiBuddy Review - 14 days throughout Japan
An extremely friendly and cost effective service. The staff were happy to answer any questions I had. The unit itself was easy to use and an excellent help throughout all of Japan Highly recommended!

Easy and reliable
We used this on recent Hokkaido visit . We had very few periods where the wifi was not in range even around Shiretoko although we did not hike in remote areas for long periods. This was good value and I will definitely use this service again!

Excellent from start to finish
Excellent company. Superior customer service. English speaking staff made things very easy with email and messaging, beginning with our initial contact. Payment was easy via PayPal. Our WifiBuddy was waiting for us at our hotel when we arrived. Nicely packaged along with an extra battery. Easy to return with free mailing envelope which we left with our hotel concierge. The device worked perfectly. We had a fast, reliable connection when we needed it, where we needed it. We do not use a lot of on-the-go internet and the Silver plan was perfect for our needs. Out and about we used Google Translate (which can be hit and miss for the printed word); Google maps (only a few times to search for restaurants in a rural location) - we are old-fashioned and prefer paper maps and getting lost; Hyperdia (the website not the app); and japan-guide.com on Tabimori. Our trips to Japan are 42 days and only once in a long train tunnel were we aware that we were without service. Docomo has good nationwide coverage. Thank you Tre and WifiBuddy for being there when we needed you. We will definitely do business with you again on our next trips.
