"Mercari Mobile" is Always a Great Deal, Even for Your First Contract

"Mercari Mobile" launched its service in March 2025 with the concept of "Flexible and Affordable Smartphone Usage." The service, which starts from 990 yen/month for 4GB of basic data, allows for easy application and management through the Mercari app, and its feature of buying and selling data capacity (gigs) for efficient use has been well-received by many customers.

Previously, "Mercari Mobile" offered limited-time campaigns and reward programs for continuing customers to make contracts more affordable. Now, to allow more customers to start with great value, we are launching a new contract benefit. In addition to irregular campaigns and continuing user benefits, all first-time contract customers will now receive a "First Month Free Benefit" and a 99% discount coupon for use on "Mercari."
