Why Do You Need a Pocket WiFi in Japan?

So many conveniences have appeared that make travelling in Japan easier than ever. HOWEVER, if there is one thing that tourists still struggle with, it's a lack of free public WiFi.
Because cyber security is something that is very important in Japan, there are hurdles for tourists to get connected without some sort of verification. Accessing free WiFi often means needing a Japanese phone number or access to e-mail to register for free Internet service. (But how you gonna get to your e-mail when you don't have Internet to start?!)Whether this for better or worse (some people do appreciate the security, not having personal information stolen is a plus) this is the state of things currently, so it's wise to get a portable WiFi device, known as pocket WiFi, in preparation for your journey!

Foreign smartphones may not be compatible with Japanese cellular networks.
Smartphones that do not support Japanese frequencies cannot use the Internet even if you purchase a prepaid SIM or eSIM. Many people ask about the problem of not being able to set up the smartphone, but in most cases, even if the smartphone can be set up, communication is not possible because it does not support Japanese frequency.

Pocket wifi is very convenient because it allows you to connect to the Internet anywhere in Japan as long as your smartphone is connected to Wi-Fi.

Pocket WiFi: The Basics

If you come from a country where using Pocket WiFi isn’t the norm, first it’s important to get an idea of just what Pocket WiFi is. Pocket WiFi is basically a portable Internet router. Pocket WiFi’s have an internal SIM card, and rely on the network service of telecom carriers on the 3G or 4G/LTE networds. Using a Pocket WiFi works just as your home Internet does. Devices have an SSID and password/key that are necessary for accessing the connection. Pocket WiFi gets its name based on its size, which fits comfortably in a pocket.

Pocket WiFi for Tourists and Short Term Visitors

So for the travelers and short term visitors to Japan, many people question whether or not they should go for a Pocket WiFi or a disposable SIM Card. (It’s probably not worth it to even think about paying roaming charges for your home provider, it’ll be expensive, and in Japan, the chances that the compatibility of the Network Bands will give you good service is pretty low…)
There are some free options, such as the WiFi found in cafes, or in major JR Stations or the Tokyo Metro subway stations, but these are not totally reliable
So lets talk about the specific benefits of using Pocket WiFi !

Why Pocket WiFi?

  • There are no compatibility issues with Pocket WiFi. With SIMs, you need to worry about Card Size and the Network bands that your phone supports. Pocket WiFis are usable by any device that can connect to WiFi, from smart phones to computers and tablets!
  • Pocket WiFi easily supports multiple users at once. Most devices can accommodate 5+ people at once
  • Pocket WiFi rentals generally have greater data allotments at higher speeds.Especially in Japan, there are specific allotments for data usage, and it’s difficult to find short term plans that are truly unlimited. You’ll notice when you go look at Prepaid SIM options, the daily or weekly limit is often quite low, and for unlimited options, they are often offering unlimited usage for the much slower 3G network. Pocket WiFi, while more expensive, has larger caps for heavy users.
  • Pocket WiFi rentals are more flexible with rental periods. Short term SIMs have a limit on how long they can be used for,currently being capped off at 30 days, while Pocket WiFi do not.
