NUWORKS Subsidiary Rocket Mobile Co., Ltd. Fully Renovates Low-Cost SIM Comparison Media "Rokkehon"

Background of the Renewal

Low-cost SIM plans and campaigns are becoming increasingly complex year by year, leading to a growing number of users saying, "I don't know which one to choose in the end." On the other hand, many comparison media outlets are not operated by telecommunications providers, making it difficult to ascertain the source of information.

Rocket Mobile Co., Ltd., as an MVNO supporting the four major networks (Docomo, au, SoftBank, and Rakuten), possesses primary information obtained from the actual application and transfer process. Taking advantage of this strength, and following its integration into the NUWORKS Group in June 2026, Rokkehon has been revamped as a "reliable low-cost SIM comparison media operated and supervised by a telecommunications provider."

Key Points of the "Rokkehon" Renewal

Operated and Supervised by Telecommunications Provider Rocket Mobile — Clarifies the operator and supervisor, establishing a system where users know who is providing the information. Takahiro Kadoya, Representative Director, serves as supervisor.

"Neutral Comparison" and Actual Data Unique to an MVNO Supporting 4 Carriers — Provides comparisons unbiased towards any specific carrier from the perspective of a provider handling the four networks (Docomo/au/SoftBank/Rakuten). Trends based on the company's own referral data will also be sequentially released.

Cross-Comparison of Fees and Networks for All 23 Companies — Compares 23 companies, including major carriers, sub-brands, and major MVNOs, based on fees, data capacity, network, and speed. Supports the quickest selection with comparison tables and recommendations by usage.

Systematized "How to Choose Without Making a Mistake" with 3 Axes and 7 Checks — Includes a guide for choosing without hesitation, even for first-time users.

Strengthened Support for Those Who Find It "Difficult to Contract" (e.g., Bank Transfer/Debit Card Support) — Enables users without credit cards to find carriers that are easier to contract with.

Improved MNP Transfer Procedures and FAQs — Provides end-to-end support from comparison to application.
