Low-Cost Mobile Services in Japan with Multilingual Support

If you are living in Japan or are planning to visit soon and if you are not a fluent Japanese speaker, you might be unsure of how to sign up for ever-important mobile services. Even if you are proficient in Japanese, the vocabulary you find in contracts, application forms and such, is quite specific and the requirements are troublesome for foreigners (the need for a credit card or a long-term visa and other issues). Furthermore, we all now also need extra data to use for remote work and online meetings.

JSelect has found three mobile service providers that make available for you a multilingual support and hassle-free application so you can get your data and be able to make calls as soon as you need. Get a full multilingual support and a smooth understanding of your bills. Check out the details below.

Benefit of Using Prepaid SIM          With the prepaid format, there is no contract, registration fee, activation nor required minimum use period. Users pay a one-off fee for the usage period and predefined data amount, so there is no hidden fee or monthly payment.

JP Smart SIM

JP Smart SIM is a SIM service designed for foreigners in Japan, offering a wide range of plans for both short- and long-term stays.

It is so popular that it has been awarded No.1 in “the Most Popular SIM Card Service among Foreign Nationals,”* making it a reassuring ally for foreigners staying in Japan.

* According to the Japan Marketing Research Organization findings. Investigation outline: Brand name and Brand Image Investigation (March 2019)

Its main features are as follows:              – Multilingual support (English, Mandarin, Vietnamese and Japanese)                                                           – Contracts can be made without a credit card or bank account.                      – No contract term constraints or cancellation penalties

If you are a foreigner looking for a Japanese SIM card, the most important thing to consider is whether the service is available in languages other than Japanese. JP Smart SIM is available in English, Mandarin, Vietnamese and Japanese, so even those who are not familiar with Japanese can use it with ease.

Another advantage is the wide variety of payment methods. Even if you are new to Japan and do not have a Japanese credit card or bank account, you can easily apply by choosing to pay at a convenience store. Of course, once you get a credit card or a bank account, you can change your payment method from MyPage.

Also, there are no contract term bindings or cancellation penalties, which is a good point for foreign residents. Even if you suddenly decide to return to your home country, you will not be charged a costly penalty fee to cancel your SIM. This means that even if you don’t know exactly how long you will be in Japan, you can apply without worry.

JP Smart SIM is available in two types, CALL SIM and DATA SIM, each with different data plans, so whether you use a lot or not, you can find the right plan for you.

For example, if you need a Japanese phone number and use a good amount of data, the JP Smart CALL 6GB plan is recommended. Its basic monthly fee is ¥2,178 (tax included), so even those who watch many videos, which use a lot of data, can use the service with peace of mind. The first month’s basic monthly fee is free with JP Smart SIM, so why not give it a try?

And for those who are staying in Japan for a short period, a prepaid SIM is also available. With JP Smart SIM, regardless of the type of SIM plan and length of your stay in Japan, you can always have multilingual support.

Credit Card  Most surprisingly, you can even find that GTN MOBILE offers a credit card service! Cobranding with a main Japan credit card company, EPOS, GTN Mobile provides a GTN EPOS Visa card to their customers.
