Advantages of Purchasing an eSIM at Narita Airport

Immediate Availability

The biggest advantage of purchasing an eSIM at Narita Airport is that you can set up your communication environment immediately after arrival.

Disadvantages of Purchasing an eSIM at Narita Airport

While purchasing an eSIM at Narita Airport offers convenience, there are several drawbacks that should not be overlooked. While it is attractive to secure a communication method just before departure without prior preparation, there are concerns such as cost performance and limited options that must be considered.

Higher Prices

eSIMs and SIM cards available for purchase at Narita Airport tend to be more expensive compared to those bought online in advance. This price difference reflects the special environment of the airport and the urgent needs of travelers.

Limited Data and Duration

eSIMs and SIM cards available at Narita Airport typically have limitations on data capacity and usage period. There are few plans suitable for stays exceeding 30 days or for users who require large data allowances.

Disadvantages Compared to Online Purchases

The disadvantages of purchasing an eSIM at Narita Airport become even clearer when compared to buying one online in advance.
If you purchase an eSIM online before departure, you can complete the setup before arriving at Narita Airport, allowing you to connect to the internet immediately upon arrival in Japan. On the other hand, if you choose to buy an eSIM or SIM card at Narita Airport, you may waste time searching for a sales location and waiting in long lines to make a purchase. Since free WiFi is available at the airport, travelers with eSIM-compatible smartphones are advised to purchase their eSIMs online using the airport's WiFi.

Not only at Narita Airport but also at other airports in Japan, SIM cards and eSIMs are available for purchase. However, since eSIMs can be bought anytime and anywhere with an internet connection, purchasing at an airport store has disadvantages such as higher prices and limited choices. For those with connecting flights, time is a critical factor. To avoid unnecessary expenses and wasted time, it is recommended to purchase both eSIMs and SIM cards online in advance.
