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.

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.



No need to worry about data connection

This was my 2nd time using the product and again I was very pleased with it. The coverage area for the device was very good and the speed provided by the network was excellent. I can totally recommend this as you can get the device directly from the airport and also leave it there, making the whole experience very easy. When using the device from morning until late evening there is a need for the external battery provided by the order. The only thing is then to remember to charge the device and the battery over night.

A great deal for long-term rental

I rented the picket 4G wifi for 3 months for use in rural okayama and found the connection and convenience to be absolutely wonderful. At first I was only going to rent a sim card, but in fact my phone was too old and foreign to work on Japanese networks. Because I was there for so long, the non-advertised deal for long term router rental was ideal for me! at about £49/month I was able to let others use my connection, and with so many GB that I could freely watch youtube and run updates and play pokemon (all heavy on data) - I had no problem using skype and VoIP services either! Truly recommended !

Simple to use

eConnect delivered this to my hotel, so it was ready to pick up as soon as I checked in. The device is very easy to use and has full English instructions. I never had an issue with the internet cutting out and it worked perfectly in Tokyo and Osaka. Good battery life, and the product also comes with a portable charger just in case, which is handy!

Simple and easy!

Simple and easy process! Ordered online, pocket wifi to be delivered to Kansai International Airport a few days prior our arrival. Provided ID to collect package at Post Office within Airport terminal. Was able to active and use straight away. Allowance of 24GB was plenty for our 14 day trip. Returned the pocket wifi at a post box in Narita International Airport terminal. Recommended!

Recommend to everyone!

The pocket wifi worked flawlessly throughout our trip to Tokyo, Osaka and Kyoto. The wifi was dependable, fast and could definitely last 10 hours without a single charge. It was also great that a portable charger came with it so it gave us the added security that if it did ran out of battery, we could give it a quick charge and be on our merry way. It charges quickly and is easy to use.

Great product

Pocket WiFi was great. Signal was excellent no matter where we were. Pocket WiFi was waiting for us at our hotel when we arrived. Easy setup and it worked with no problems. Very easy to carry around in pocket or backpack. Popped everything in return envelope and dropped off at the post office in the airport with ease. Would definitely use again and would highly recommend.

Simply Fantastic

This was a seamless service that made our 6 week trip around Japan as stress free as possible. It was ready and waiting at our hostel and was super straightforward to put everything back in the envelope provided and post back at the end of our trip. The battery last most days and comes with a charge block just in case. We had good connection throughout Japan and even on the subway. Cannot recommend this enough, great price as well.

Great device!

We were so happy we got this pocket WiFi, we brought it with us everywhere, it was light, we used it to check email, WhatsApp, Facebook, google maps and safari. It was fast and not problems whatsoever! Highly recommend it! Easy to use and very simple instructions to send it back, just put it in the provided envelope and drop it in a postal box. Loved it!

Perfect !

Excellent service. Easy to pickup and return at Narita Airport. Excellent network, wherever I was, I was connected. The battery was good also, I rarely had to recharge it during the day.

The price is nice also so I never hesitate to choose eConnect for my pocket wifi in Japan :D

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.
