Which is Better for Japan Travel? Comparison of eSIM, SIM cards, and Wi-Fi routers

Below is a table summarizing the three features and considerations.

Based on the features and disadvantages, please choose the most suitable option according to your usage scene and purpose.

Differences between Japan eSIM and SIM cards

eSIM and SIM cards are both used for communication with smartphones overseas. Although they have many similarities, there are several significant differences. SIM cards are plastic cards that are inserted into dedicated slots on smartphones. When changing carriers, for example, it is necessary to physically exchange this card.

On the other hand, eSIM does not exist as a physical card. It is an electronic SIM that is already built into the device. Carrier changes can be made through settings on the device, eliminating the need for physical card exchange.

The setup was easy, and there were no issues with the signal! I will use it again when I return temporarily!

3 Benefits of Using Japan eSIM

1. Can be used immediately upon arrival in Japan

One of the major benefits of eSIM is that you can have internet access smoothly from the moment you arrive at the airport in Japan.

With traditional SIM cards, you would need to purchase them at the airport shop or receive a SIM card that you pre-ordered. However, with eSIM, you can download it in advance and connect to the network as soon as you get off the plane. This allows you to efficiently arrange for taxis or navigate your way to the hotel, making your trip more convenient.

2. No risk of loss or damage

Traditional SIM cards are very small and require careful handling. Especially when replacing them during your trip, the risk of loss or damage increases.

On the other hand, eSIM is not a physical card, so you don't have to worry about losing or damaging it. There is no need to go through the hassle of opening the SIM tray with a small pin or worry about accidentally dropping the SIM card.

3. Dual SIM capability

By utilizing eSIM, you can use dual SIMs. Dual SIM allows you to use two networks on one smartphone.

This means you can have a SIM card that can be used in Japan and another one for overseas, allowing you to smoothly switch network environments when traveling between Japan and other countries. With dual SIM, you don't have to go through the hassle of contracting for internet access every time you visit multiple countries.

3 Drawbacks of Using Japan eSIM

1. Limited device compatibility

To use eSIM, you need a smartphone or tablet that supports eSIM. While newer models are becoming compatible with eSIM, older models or some mid-range to low-end devices may not support eSIM.

This means you will need to check whether your current device can use eSIM, which can be an extra step. If you need to purchase a new device to use eSIM, you also need to consider the associated costs.

2. Cannot be used on multiple devices

Traditional SIM cards can be switched between devices. Therefore, you can use one SIM card on multiple devices. However, since eSIM is embedded in the device, it is difficult to easily move it between multiple devices. Therefore, if you want to use multiple devices during your trip to Japan, it may be inconvenient.

3. Cannot use a phone number

With eSIM data plans, you may not be provided with a unique phone number or may require an additional fee. This may cause inconvenience in situations where a local phone number is required, such as making restaurant reservations or contacting hotels. Traditional SIM cards often provide a phone number along with data communication, so this is an important consideration when considering using eSIM.

3 Tips for Choosing Japan eSIM

1. Is the price affordable?

The first point to consider when choosing eSIM is the price. Expenses during a trip to Japan can include transportation, accommodation, and meals, so you would want to minimize the cost of communication. However, if you only pursue affordability, there may be issues with communication speed, data capacity, and support system. Make sure to carefully check the services provided and choose a plan that offers good cost performance.

2. Is the data capacity sufficient?

When choosing eSIM, the data capacity is an important factor. Especially if you plan to stream videos or download large amounts of data, an unlimited data plan is recommended. However, unlimited plans tend to be more expensive, so choose according to your budget for your trip to Japan.

3. Are there positive reviews?

To choose a good eSIM, check third-party reviews and feedback. This will help you judge the quality and reliability. Evaluations from users who have already used that eSIM can be very helpful in understanding the actual user experience and the support provided in case of any issues.
