On March 4, 2025, Mercari, the popular Japanese marketplace app, announced its entry as a Mobile Virtual Network Operator (MVNO) with the launch of its service, "Mercari Mobile." This innovative service allows users to trade their unused data seamlessly through the Mercari app, significantly enhancing user experience and providing cost-effective options for smartphone usage.
The service presents two flexible monthly plans: for 990 yen, customers can access 2GB of data, and for 2,390 yen, they can utilize 20GB. Both plans include taxes and are crafted to cater to varying usage requirements. The standout feature of "Mercari Mobile" is the ability for users to buy and sell data bandwidth directly among themselves, creating a dynamic marketplace. Users can set their own pricing for data sales, starting at 200 yen per gigabyte, with 10% of the sale price taken as a transaction fee, which is standard across the platform.
"The data trading service allows for flexible adjustment of rate plans," said Takeshi Nagasawa, CEO of Mercari, emphasizing the benefit of adapting to users' needs and consumption patterns. With the app, individuals who have surplus data can list it for others to purchase easily. For example, if someone needs extra data, they can access listings posted by others without cumbersome processes.
Access to "Mercari Mobile" begins with the iOS version of the Mercari app, with Android compatibility expected to follow shortly. All transactions are conducted within the app, simplifying the application and payment processes. The service utilizes the network infrastructure provided by NTT Docomo initially, enabling voice calls, SMS, and data services.
While the immediate offering is limited to eSIM technology—requiring users to use compatible devices—Mercari has announced plans for future enhancements, such as the introduction of physical SIM cards and potentially incorporating the au network for broader coverage. Customers can expect domestic call rates of 22 yen every 30 seconds, with registration fees set at 3,300 yen for new users.
Importantly, any unused data does not roll over to the next month, urging users to utilize their allocated bandwidth or trade it within the monthly timeframe. This approach uniquely positions Mercari to capitalize on its vast user base—approximately 23 million monthly users have made the app highly successful since its inception.
This new MVNO service aligns with Mercari’s broader mission of creating value through efficient resource circulation. Starting operations in 2013, Mercari has been instrumental in establishing easy-to-use platforms for individuals to buy and sell goods. The innovative data trading feature of "Mercari Mobile" extends this model of peer-to-peer transactions beyond physical goods to digital resources, showcasing how smartphones can be used more flexibly and economically.
For users accustomed to tracking and managing their spending through the app, this new service introduces elements of savings and flexibility. Users can not only profit from their surplus data but also conveniently utilize those profits for making purchases within the Mercari ecosystem or use the "Merpay" payment service for broader transactions.
Looking to the future, Mercari envisions continuous development and adaptability within its services. Nagasawa hinted at the potential for incorporating flat-rate calling options and other payment methods, enhancing user experience and engagement even more. With these developments, Mercari seeks to encourage users to switch from traditional carriers by offering compelling, personalized solutions more aligned with contemporary telecommunications needs.
Through "Mercari Mobile," the company hopes to draw more customers who seek not just savings but also empowerment over their data usage and payment choices. This venture is yet another step forward by Mercari, focusing on maximizing the utility of both financial and digital resources, ensuring every user can contribute to and benefit from the marketplace.
The launch of "Mercari Mobile" marks not just the introduction of another telecommunications service but also reflects Mercari's commitment to delivering relevant, user-friendly solutions. With the ability to trade data and manage mobile services directly within its app, Mercari is poised to redefine user interactions with mobile telecommunications.
