Is Pocket WiFi in Japan Truly Unlimited? | wifi rental japan

Basically you can use unlimited 4G data with advance mode of 603HW. However, unlimited settings may not allow you to stay connected if you are using it in places like subway and basement. In addition to this, if your room is surrounded by walls, there is a possibility that radio wave from outside cannot be received well. In this case, you can relocate pocket WiFi to the place like near window. However, it still may not work depend on your surrounding environment.

There is a solution for this. Unfortunately, this solution will not lead you to use unlimited data; however, you can still stay connected under difficult environment. This applies to almost all pocket WiFi in Japan. When a WiFi rental company in Japan says you can use unlimited data, it means you can use unlimited 4G data, not 4G LTE. Some places will say you can use unlimited 4G LTE. In this case, the usage of 4G LTE is limited to 1-3 Gigabytes per day and speed limit will be applied after using all of these.

What is 4G? and 4G LTE?

So what is the difference between just 4G and 4G LTE? It’s simple. Let’s think of an image of Ban diagram. There is a big circle and its name is 4G. Inside this big circle there is one another small circle and the name of this is 4G LTE. Yes, 4G LTE is under 4G.

(1) 4G AXGP

For better understanding, let’s use Y!mobile 603HW as an example. In case of 305 ZT, advance mode provides 4G AXGP whild standard mode does 4G LTE. AXGP is network name of Softbank, which was made to provide network service to businesses and companies who use Softbank network. This AXGP is considered to have high efficiency in radio wave since it uses one frequency. AXGP also uses high frequency(2.5GHz) and this is why the connection inside building or room can be weak.

(2) 4G LTE

Regarding LTE, it stands for Long Term Evolution, which is a standard for high speed wireless communication for mobile devices. This is also called as FDD LTE in Japan. Compare to other communication networks, the speed of LTE is more than 100 Mbps for download so you can get online basically everywhere. There is almost no places where you cannot use LTE unless you are in the middle of mountain, water, or some islands where doesn’t have radio wave. However, since they use different frequency for download and upload, the use is not efficient. You will feel using up LTE is very fast.

my pocket wifi doesn’t work

Your pocket WiFi shows 4G on the screen but you cannot get online with your device? Here are some solutions you can check out.

(1) Where are you using Pocket WiFi?

If you are using your pocket WiFi in a place like subway, radio wave cannot be received well due to surrounding environment. Underground anywhere including subway and basement will not allow you to use unlimited data. Or maybe you can use it only when you arrived at some stations only.

In addition to this, some of you may have troubles with pocket WiFi in the room as well. It also happens because of the structure of building. If the building is mainly made with steel frame, it will disturb radio waves from outside to reach into your room. In this case, you can relocate your pocket WiFi near window and try again.

(2) How many gigabytes did you use for 3 days?

It applies to most of pocket WiFi in Japan. If you use 10GB within three days, you will have speed limit for preventing congestion. The speed limit usually applies after 6 p.m. to 1~2 a.m. since many people use network connection at this time. If you are using pocket WiFi alone, it will be hard to use more than 10GB within 3 days unless you watch high quality videos and download heavy files all the time. However, if you are sharing one router with 4-5 people, please be careful to not exceed 10 GB within 3 days.

(3) Did you change to LTE mode?

For Y!mobile 603HW, if you use more than 7 GB with standard mode you may not be able to access to WiFi again. standard mode let you use 4G LTE, which is also available in the subway and underground. However, if you exceed this there is no other way to release limit. You will not be able to use advance mode as well. The only way to release limit is to wait until next month comes.
