Basic knowledge of SIM cards
SIM cards are an essential element when connecting devices such as smartphones and tablets to the Internet. As communication technology evolves, there are more options such as 3G, 4G, and LTE, but SIM cards are essential to make use of these. Especially for travelers visiting Japan from overseas, preparing an appropriate communication environment is an important preparation to make your trip more comfortable.
Why do you need a SIM card?
SIM cards are the key that connects devices to communication carriers. This small chip stores the user’s contract information and individual authentication data, allowing you to make calls and use the Internet. Especially in countries like Japan where Wi-Fi is available for free in limited places, using a SIM card provides the convenience of being able to communicate comfortably anywhere.
What types of SIM cards are there?
There are two main types of SIM cards: prepaid and postpaid. With prepaid SIM cards, you purchase a certain amount of communication data in advance, and when the data runs out, you need to purchase more. In contrast, with postpaid SIM cards, you are charged monthly according to the amount of communication used. Prepaid SIM cards are particularly popular among travelers, and they are supported by the fact that they can be easily started on the spot.
How to set up a SIM card
Setting up a SIM card is surprisingly simple. First, insert the SIM card into your device. Next, enter the access point number (APN) specified by your communication provider from the device’s settings screen. In many cases, you will be able to communicate within a few minutes with just this. If you have difficulty setting it up, it is a good idea to get support when purchasing or check the instructions that came with it.
SIM cards available in Japan and their features
In Japan, a wide variety of SIM cards are available for travelers. With so many options, it is important to choose one that suits your purpose and budget. Understanding the differences in price, communication speed, data capacity, expiration date, etc. will help you find the best SIM card.
Major SIM card providers and their features
There are several major providers in Japan, each offering their own unique services. For example, “IIJmio” features affordable prices and stable communication speeds, while “b-mobile” offers a wide range of plans for short-term travelers. There are many other options, so the key is to compare communication ranges, prices, and plan contents before making your selection.
Price and data volume
The price of SIM cards varies greatly depending on the provider. A typical prepaid SIM card offers data plans ranging from several hundred MB to several tens of GB, with prices ranging from 500 to several thousand yen. Choose the appropriate plan depending on the number of days you will be traveling and how often you will use the Internet. It is a good idea to calculate the amount of data you will need in advance to avoid unnecessary expenses.
Communication speed and range
Communication speeds vary depending on the provider, but all plans offer speeds that are sufficient for everyday use. In addition to general web browsing and SNS use, you can also comfortably watch videos and use online map apps. In addition, most providers cover the entire country of Japan, but there may be restrictions on the available areas in some regions.
Points to note when purchasing a SIM card in Japan
When purchasing a SIM card in Japan, it is necessary to keep in mind several points. By making the appropriate preparations, you can avoid trouble after purchasing and maintain a comfortable communication environment during your trip.
Confirm device compatibility
First of all, the top priority is to check whether your smartphone or tablet is compatible with the SIM card you plan to purchase. If the communication method (3G, 4G, LTE, etc.) or frequency band does not match, communication may not be possible. It is important to check the specifications of your device in advance and compare them with the compatibility list provided by your provider.
Choosing a place to buy
You can buy SIM cards at airports, electronics retailers, online shops, etc. At airports, you can buy them immediately after you arrive, but the price may be a little high. At online shops, you can buy in advance and have them delivered so that you can use them immediately after you arrive. Be sure to check the special offers and promotions for each store.
Expiration date
Prepaid SIM cards have an expiration date. It is important to choose a card that matches the length of your trip, as communication often becomes unavailable within a few days to a few weeks after activation (initial setup). Check the details before purchasing to avoid unnecessary expenses.
Number portability (MNP)
In Japan, some providers offer the number portability (MNP) service. This allows you to keep your current phone number. However, not all providers support this service, so you should check in advance.
Summary
To enjoy your trip to Japan comfortably, it is essential to have a good communication environment. When choosing or purchasing a SIM card, it is important to check the compatibility of your device, choose a place to purchase, understand the expiration date, and whether or not number portability is available. If you prepare with these points in mind, you will be able to obtain a smooth communication environment. Please make sure to plan your preparations carefully to make the most of your trip in Japan.
