WiFi Data Capacity

If you rent a pocket WiFi router, you might think that it is good to select a plan giving you much data amount because you must not want to worry about data limitation.
Yes, there are lots of service plans described as "unlimited data."
However, there are almost no plans that actually provide you "unlimited data."

Most services limit data speed when you over a certain amount of data capacity.
Although those limits are vary depending on sales efforts by each company, it can be said that you can believe a certain range of data capacity will be assured when a company shows their data limitation policy fairly like "The data speed will be limited if you spent over 3GB per day."
If you want to use much data, it is good to understand such limits.

Research results by OCN (the largest Japanese internet service provider) show that 90 percent of Japanese consumes only within 100MB/Day (or 3GB/Month).
Although international travelers to Japan may spend much more than that, 200-300MB/Day (or 6GB-10GB/Month) is 2-3 times larger than that of average Japanese consumption.
So, we can say that 200-300MB/Day will be sufficient for single use.

A WiFi plan with 3GB/Day will be sufficient for that purpose.
