What is Rakuten Mobile?
Rakuten Mobile is a mobile phone service operated by the Rakuten Group, a major Japanese internet company. Launched in April 2020 as Japan's fourth major mobile carrier, the service has attracted attention for its innovative pricing structure and wide range of services. Its greatest feature is its low-cost, high-quality service provided using its own Rakuten network. This cost-effective operating structure allows it to offer plans that are significantly cheaper than those of other major carriers.
Rakuten Mobile only offers one pricing plan, the "Rakuten Ultimate Plan." Its simplicity and ease of understanding are also a major attraction. You only pay for what you use. From light users with limited data usage to heavy users who want to use as much data as possible, Rakuten Mobile offers pay-as-you-go plans to meet a variety of needs.
If your monthly data usage is 3GB or less, the monthly fee is 1,078 yen. If your monthly data usage is between 3GB and 20GB, the monthly fee is 2,178 yen, and if it exceeds 20GB, unlimited data usage is applied for a monthly fee of 3,278 yen. In other words, the monthly fee is set according to your monthly data usage, and even if you use more than 20GB, your monthly basic fee will never exceed 3,278 yen.
By making good use of Rakuten Mobile's campaigns, you can significantly reduce your communication costs.
Rakuten Mobile also has no minimum contract period, so it's recommended for foreigners who are staying in Japan for a short period of time. Furthermore, there are no cancellation fees, so you can cancel at any time. (Note: If you have any remaining optional service fees or installment bills for your smartphone device, you will need to settle them.)
