If you forget to purchase a SIM card in your home country, don’t worry! Major Japanese airports now have SIM card vending machines for your convenience.

eSIM: An Alternative to Physical SIM Cards

One concern when using a physical SIM card is the risk of losing or misplacing it. eSIM, on the other hand, eliminates the need for a physical card and allows you to use the service directly on your device. In the U.S., the iPhone 14 series, which supports eSIM, was released in 2022, and other carriers are expected to follow suit.

In Japan, companies like mobal, Sakura Mobile, and Nippon SIM for Japan also offer eSIM services. For example, mobal provides eSIM services for 1,920 yen and up, offering 1GB of data for 8 days. Sakura Mobile offers a 10-day eSIM package with 5GB of data for 3,350 yen as of August 2023. If your smartphone supports eSIM, these companies are worth considering.

While SIM cards are a popular choice for staying connected in Japan, portable Wi-Fi routers are another option to consider. In some cases, these routers can handle a larger amount of data compared to SIM cards. However, they may also be more expensive.

For example, the Ninja WiFi router costs 770 yen per day with a data limit of 3GB per day. However, there is a 20% discount available through MATCHA, bringing the cost down to 3,080 yen for 5 days. This is a similar fee to what you would pay for a SIM card. The advantage of a portable Wi-Fi router is that it allows multiple devices to connect to the internet without the need to change SIM cards.

FAQs about SIM Cards in Japan

Q1. Is a Voice SIM or data-only SIM a better choice?

A Voice SIM comes with a Japanese telephone number, while a data-only SIM does not. Messaging apps like WhatsApp, Messenger, and LINE have become popular alternatives for communication, so you might wonder why you would need a Japanese phone number if you’re not a resident. However, having a phone number has its advantages. For example, you can make emergency calls to the police or fire department in case of trouble. Emergency calls can be made in languages other than Japanese, making this feature especially useful. Additionally, some services in Japan, such as the popular electronic payment app Pay Pay, require a registered phone number. If you’re interested in having a phone number, mobal offers Voice SIM cards that are suitable for short-term trips.

Q2. What does “unlimited data” mean?

Some SIM cards offer “unlimited” data usage. However, it’s important to note that there are limitations to this claim. Most SIM cards with unlimited data can handle around 2 to 3GB per day without any issues. However, if you exceed this capacity, your data speed may be reduced. While you will still have access to the internet, the speed at which data is transferred will be considerably slower.

Q3. Can I change the SIM card of my smartphone?

If your smartphone is SIM-locked, you won’t be able to change the SIM card. SIM-locking is common in some Japanese and American smartphones, although most Asian countries offer SIM-free phones. If you have a SIM-locked phone, you can contact your carrier to inquire about unlocking it. Additionally, not all SIM cards are compatible with every smartphone model. It’s important to check the compatibility list on the official websites of SIM card providers before making a purchase.

Q4. How should I handle my original SIM card?

If you plan to change the SIM card in your home country, make sure to store the original one in a safe and dust-free place. If you plan to replace the card in Japan, it’s recommended to bring a SIM card case to keep it protected. SIM card cases can be purchased on Amazon and other retailers.

By choosing the right SIM card or portable Wi-Fi router, you can stay connected and make the most of your time in Japan. Whether you prefer the convenience of a SIM card or the flexibility of a portable Wi-Fi router, there are options available to suit your needs. Happy travels!
