Many visitors to Japan often wonder if their Japanese data SIM card can be used to make calls or send SMS messages. This is an important consideration for many travelers. In this article, we will answer this question and provide some practical alternatives to make communication in Japan easier.

Limitations of Japanese Data SIM Cards

In Japan, most data SIM cards available for short-term visitors mainly provide data services without traditional calling or SMS capabilities. This is because Japanese telecommunications regulations have strict identity verification requirements for issuing SIM cards that can make calls. Specifically, long-term residency proof such as a residence card and a valid Japanese address are required.

These regulations are in place to prevent illegal activities and protect users’ privacy and rights. Therefore, short-term visitors who do not meet these requirements cannot obtain SIM cards with calling and SMS functions.

Alternative 1: Using Communication Apps

Although short-term visitors cannot use traditional methods to make calls or send SMS, modern technology offers many alternatives. Here are some recommended options:

WhatsApp

This globally popular communication app supports not only messaging but also voice and video calls. As long as your friends or family also have WhatsApp installed, you can use the data from your SIM card to make calls and send messages.

LINE

In Japan, LINE is one of the most popular communication apps. In addition to standard messaging and calling features, LINE offers a rich collection of stickers and games, making communication more enjoyable.

Skype

Skype is suitable for travelers needing to make international calls. It supports voice, video calls, and messaging with relatively low fees. You can enjoy its services using the data from your SIM card.

Alternative 2: SIM Cards with SMS Functionality

If you only need to send SMS messages, consider renting a SIM card that offers SMS functionality. For example, CDJapan Rental provides a SIM card with 25GB of high-speed data and SMS capabilities per month, making it an ideal choice for short-term travelers.

These SIM cards can send and receive SMS messages within Japan, making them perfect for travelers needing to stay connected internationally.

How to Choose the Right SIM Card

When choosing a SIM card, consider your primary needs first. If your main requirement is internet access and using communication apps, a standard unlimited data SIM card is the best choice. If you need to send SMS messages, choose a SIM card with SMS functionality.

Data Allowance

Ensure the data allowance meets your needs, especially if you plan to use video calls or browse the internet frequently.

Speed

Check if the SIM card’s speed can meet your requirements. Generally, high-speed SIM cards are better for users needing a stable connection.

Price

Compare the prices of different SIM cards and choose the one with the best value.

Conclusion

For short-term visitors to Japan, using a data SIM card for calls and SMS is not feasible. However, this does not mean there are no other solutions. By using communication apps like WhatsApp and LINE and choosing the right SIM card, you can easily stay connected. Prepare well before your trip, select the most suitable communication method, and make your visit to Japan smooth and worry-free.
