Great service!

eConnect makes it so easy to pre-book your Pocket WiFi before leaving home - with the device waiting at the hotel check-in - ready to go! We had no connection issues, and would use eConnect again, when we next travel to Japan.

Highly recommend!

Collected from post office at Narita, easy to set up, no issues with connectivity. Lovely to have a battery pack to charge on the go. Three of us were connected to it and none of us had any issues. We got the 50GB package which was more than enough. We switched to the hotel's wifi whenever we were at the hotel. It was fantastic to be connected to google maps to help us navigate our way around Tokyo. It came with a pre-addressed and pre-paid envelope (We also got an email reminding us to drop it off before leaving the country). All we had to do was place the router and everything else in the envelope and drop off at a post office. We dropped it off at the post office at Narita. No complaints whatsoever, again - highly recommend!

Super easy to collect, and fast, unthrottled speeds for our whole trip

Was super easy to collect the pocket wifi at the airport, and just had to drop it in a mailbox at the end with the provided packing envolope. We had super fast speeds for the whole 16 days of the trip with no throttling. Will defintely be using again on the next trip to Japan.

Zero issues, exactly what we needed! 11 Stars

This device made our travels across Japan (Tokyo, Kyoto, Izu Peninsula, Kamakura, et al.) so much more excellent than they would have been otherwise. Sure, we could have solely relied on paper maps, guide books, and the (very common) kindness of strangers to find our way, but while we did all of those too, it was just so convenient to use Google Maps and Yelp apps to find & learn about that special shrine, that temporary attraction, that offbeat restaurant. (We also had many, many serendipitous, spontaneous moments - we weren't slaves to our phones!) My wife, 2 teenage kids, and myself used the hot spot each day of the trip, including on our tour bus and shinkanzen trips. 4G was the best, it only disconnected in really remote areas in Izu and in remote spots on the bullet train. Booking in advance saved us a bundle. The device itself came with very straightforward instructions, and troubleshooting tips, which we fortunately never had to read because it worked flawlessly on start up. I'd give it 11 stars if possible. No-brainer, I'll rent again on my next trip. Thank you!!! Tip: On the first day of use, I learned that like many devices, it can heat up, which if hot enough, will shut down. I had buried it in the backpack I was carrying around all day in 90F weather, so it (and I) got super-toasty. After that, I kept it zipped up in an outside pocket of my backpack, and had no further problems.

Data Cap

We often get questions about data cap and unlimited data plan availability.
As explained in our blog post, every Pocket WiFi in Japan has a monthly data limit at some point where the internet speed is severely restricted under the Fair Usage Policy.
Even if you found a Pocket WiFi labelled as Unlimited Data, you should not assume that you could use data unlimitedly without any speed restrictions because you cannot.

At eConnect Japan, we set 1GB * rental days for the default data allotment which we guarantee that you can use without any possible speed restrictions.

We believe this data allowance is more than enough for normal travel use but we can add extra GB upon request for those who are in need.

Tips: use hotel wifi or other wifi when you download or upload large files.

Bonus: Order now and get extra 10GB data for free!

What's the speed like?

You might wonder how fast 4G speed would be. Our 4G model is definitely one of the fastest in Japan, the country ranks high in mobile internet speed. We have not heard any complaint about its speed.
So be assured that your internet experience will be comfortable and smooth.

Having said that, it's important to note the figures for both download and upload in the specification above are the theoretical ones at best effort. In the actual use case, the speed will be as not high as those numbers because you are not the only one using the network at any given time. Since the mobile network is shared with many users, the traffic that can go through at a time is limited. Simply put, when more people using more data, the speed will not go that fast.

For return, all you have to do is put all items in the prepaid return package we provide and drop it in a post box in Japan on the last day of your rental.

  • Set-up Guide

Precaution Statement for the Pocket WiFi Rental

  • The connection speeds shown above are provided on best effort basis.
    Actual speeds vary depending on location and connection status.
  • Network provider (Softbank) reserves the right to restrict the connection speed for those who have used significant amount of data in a short period of time (or for those whose network activities are considered as suspicious).
  • Your device must be WiFi enabled.


It is the day we ask you to post the rental items back to us. You can simply drop it in any post box in Japan. We request that you do so by midnight on your return date.

You do not have to worry about how long it will take to get to us as long as you post it in time.

Once your data consumption reaches your total data allotment, it is subject to speed restriction from the network operator.
The network operator does not disclose when (or in what cases) the restriction applies or how slow it will be under the restriction.

Please be assured that the internet connection won't be cut off.

It depends on our data pooling status at the point of your purchase request. It might be possible in most cases but we cannot guarantee.

Please email us atinfo@econnectjapan.comif and when you need additional data.

With the extra portable battery we provide, it normally lasts for a whole day.

However, it really depends on how often and how long you use the device.

It comes with a SIM card inside as a unit. You do not have to buy anything extra.
