The ¥3,278 monthly unlimited plan is presented as the main attraction of switching from au to Rakuten Mobile, with detailed explanations of potential monthly savings and various campaigns. The process can be completed online using SIM unlocking and MNP one-stop service.
Switching from au to Rakuten Mobile reduces the monthly base fee, and the unlimited plan is priced at ¥3,278 per month regardless of data usage. The article explains that this may substantially reduce monthly payments compared with au's unlimited plans.
Rakuten Mobile offers numerous campaigns combining a SIM-only contract with a device purchase, including the Mikitani campaign and other benefits. SIM-only contracts may qualify for rewards of up to 14,000 points, while packages including a device purchase may offer rewards worth up to ¥40,000.
The switching process involves first unlocking the SIM, then obtaining an MNP reservation number, unless MNP one-stop service is available, preparing the required documents, applying online or at a store, and completing activation and data transfer after receiving the SIM or device. Online applications are described as the easiest option, and checking the campaign conditions in advance is considered important.
Points to note include losing access to bundle discounts such as au Hikari, the inability to use some au-related services, and the fact that au email portability is an optional paid service.
