What is Pocket WiFi?

Pocket WiFi is a small, palm-sized WiFi router that lets you connect to the internet anywhere. Simply by turning it on, you can create a WiFi spot, making it a convenient item that lets you connect multiple devices, such as smartphones, tablets, and computers, to the internet at the same time. You can use it safely even while traveling!

Benefits of Pocket WiFi

1. Simultaneous connection to multiple devices
The biggest appeal of Pocket WiFi is that it can connect to multiple devices simultaneously, making it ideal for group trips, as you can share communication costs with family and friends.

2. Large-capacity data plans
Large-capacity or unlimited data plans are often available, which is convenient for travelers who frequently watch videos or use maps. You can use the service comfortably without worrying about data usage.

3. Easy to connect
Connecting to Pocket WiFi is extremely easy, requiring no dedicated app or complicated settings. You can expect a relatively stable connection within mobile communication areas, making it easy to use anywhere in Japan.

Disadvantages of Pocket WiFi

1. It needs to be carried around
The disadvantage of Pocket WiFi is that you have to carry a dedicated device with you, which increases the amount of luggage you need to carry. Also, there is a risk of misplacing or losing it, so be careful.

2. Risk of running out of battery: Pocket WiFi devices require frequent charging, and the battery may run out during long trips. It is especially convenient for travelers who spend long periods of time outside to carry a portable battery with them.

3. Unstable connection
The connection status of Pocket WiFi depends on the signal strength of the carrier you use. Please note that the signal strength may be weak in rural areas or mountainous areas.

What is an eSIM card?

An eSIM card is an electronic SIM card that replaces a physical SIM card and is built into devices such as smartphones and tablets. There is no need to physically insert a SIM card; simply activate it on a compatible device to easily use mobile data.

Benefits of eSIM cards

1. No device required, no hassle
Because the eSIM card is built into the smartphone itself, there is no need to carry an external device like Pocket WiFi. The appeal is that there is no extra baggage and it can be used easily while traveling.

2. Immediately available
After purchase, eSIM cards can be activated online instantly and easily set up while preparing for your trip or once you arrive.

3. Flexible plan changes possible
eSIM cards offer peace of mind if your data usage exceeds your expectations during your trip, as you can change plans or purchase additional data as needed. They are especially suitable for short-term stays or solo tourists.

Disadvantages of eSIM cards

1. Compatible models are limited
To use an eSIM card, your current mobile device must support eSIM. While most iPhone XS and newer models and the latest Android devices support it, older models and some budget smartphones often do not.

2. Additional costs are likely to occur
Data plans on eSIM cards may have lower capacity than Pocket WiFi, so frequent video streamers or travelers who require long-lasting connections may incur additional costs.

3. Cannot be shared by multiple people
An eSIM card can only be used with one device, so if you're traveling with multiple people, each person will need to purchase their own data plan.

Comparing Pocket WiFi and eSIM for different purposes! How to choose

Many people are probably wondering whether to choose Pocket WiFi or an eSIM card. Pocket WiFi excels at large data capacity and multiple device connections, while eSIM cards are appealing for their ease and instant use. Let's compare the features of each and enjoy a comfortable trip with the communication method that suits you best!

For short-term stays

For short trips, convenience and ease of use are essential to make the most of your limited time. Pocket WiFi can take some time to process, but it's convenient if you need large amounts of data. On the other hand, eSIM cards can be set up in advance and can be used immediately upon arrival, eliminating the need to collect them at the airport.

For group travel

Pocket WiFi allows you to connect multiple devices to one device, making it convenient for families and groups of friends traveling together and making it easy to share data costs. On the other hand, eSIM cards require each user to purchase a separate data plan, which can increase the overall cost.

If you want to keep costs down

Pocket WiFi is available with monthly or unlimited plans, making it convenient for longer stays or those with heavy data usage, while eSIMs are often cheaper for short-term use and are better suited for travelers with light data usage.

When connection stability is important

Pocket WiFi is stable in urban areas like Tokyo, but the signal may be weak in rural or mountainous areas. On the other hand, eSIM cards offer fast and stable communication, especially with 5G-compatible smartphones. However, both are affected by the carrier and area, so it's a good idea to check the signal conditions at your destination.

Working on the move

Pocket WiFi is convenient for working on the go because it can connect not only smartphones but also tablets and computers at the same time. On the other hand, eSIM card tethering can connect computers, but it can easily exceed your data limit, incur additional charges, and drain your smartphone's battery faster.
