Cheap SIM cards in Japan

The 2022 Oricon survey awarded No.1 in customer satisfaction for low-cost SIMs. It is quite trusted and popular by Japanese consumers. The data speed is sustainable. There are five plans provided: "2GB Plan (2GB)", “4GB Plan (4GB)”, “8GB Plan (8GB)”, “15GB Plan (15GB)” and “20GB Plan (20GB)”. You can transfer the remained data traffic to the next month, except for the Pay-as-you-go Plan. Even when the data traffic is limited, the first part of the Web page is loaded quickly so that simple pages are able to browse comfortably all the time. There is a Web page explaining how to buy a SIM for the non-Japanese so is easy to understand.

CENTER MOBILE offers only SIM cards. Since they do not sell SIM and smartphones together, you must prepare the phone yourself. There are four rate plans: 3GB, 12GB, 20GB, and 50GB. Each rate plan provides Voice-Call Plan and Data-SIM Plan. In addition, there are reasonable unlimited call plans such as 20GB + unlimited calls within 5 minutes for 2,970 yen (including tax) and 20GB + unlimited calls within 10 minutes for 3,300 yen (including tax).
CENTER MOBILE's unique feature is its discount on a monthly fee. You can earn points by watching ad videos (5-30 seconds) or downloading specified apps via the app called PLAIO. You can reduce the monthly fee by using these earned points. If you watch the ads in your free time, the monthly payment could be 0 yen. Therefore, we recommend CENTER MOBILE to foreigners who want to save on the monthly payment of a SIM card. They offer Spring New Life Support Promotion by May 31, 2023. The promotion enables all plans to be practically 0 yen for two months by making the first payment.
You can communicate comfortably throughout Japan because CENTER MOBILE uses Docomo lines. However, if you use over 5GB of data in three days, communication speed is limited. In addition, the minimum usage period is at 12 months. If you cancel the service in the middle of the period, a penalty fee occurs at 1,100 yen. After a year, you do not have to pay the cancellation fee. Therefore, we recommend this low-cost SIM card for foreigners who stay in Japan for over a year.

There is a cheap SIM card for foreigners staying in Japan which is provided by mobal from the UK. If you have a SIM lock-free smartphone, you can use it without problems. The greatest benefit is that it is possible to apply without holding a residence card or credit card. There are many pricing plans: a “Monthly Payment Plan” for which you purchase a SIM card and then select the data capacity (1GB, 5GB, 10GB, 30GB), and also short-term plans (30 days, 60 days, 90 days) for those who need a voice & data sim for a short stay. Even if you choose the Monthly Payment Plan, the minimum usage period is only one month so that you can stop using anytime you would like. No penalty for any cancellation is one of the best points of mobal. It is convenient to use for foreigners who stay in Japan shortly, such as short-term study abroad, working holidays, and business trips. Also, customer support provides help in English and Chinese. If you stay for less than a year, it is a good choice for a low-priced SIM card.
