Rakuten Mobile Starts Full-scale Sales in Japan for SMS Service, “Symworld™ CPaaS SMS API”

May 18, 2023, Tokyo, Japan – Rakuten Mobile, Inc. today announced the start of full-scale sales in Japan for “Symworld™ CPaaS SMS API”*1*2, its enterprise mobile short messaging service developed by Rakuten Symphony Singapore Pte. Ltd., a subsidiary of Rakuten Symphony, Inc.

Symworld™ CPaaS SMS API allows companies to send SMS (short messages) to customers' mobile phones and smartphones with individual, consolidated and scheduled SMS delivery available. Developed and operated in-house by the Rakuten Group, this service offers carrier-grade SMS delivery at one of the lowest price points in the industry at 8 yen per message (excluding tax).

The service utilizes direct carrier connection as its transmission method to realize swift and stable communications between companies and customers. By connecting directly to four Japanese mobile carriers, including Rakuten Mobile, SMS can be sent safely with high delivery rates and low delays. In addition, free operational support by telephone and email is provided in Japanese 24 hours a day, 365 days a year.

The mobile messaging service is available in two options. The first is via SMS API connection transmission, which works by connecting this service with the customer's system via API. Establishing an API connection makes it possible to link with SMS authentication systems used for member registration and other processes requiring identity verification, as well as with in-house business tools currently in use.

The second mobile messaging service is via dashboard transmission which allows the customer to send messages from a simple dashboard interface featuring visualized information displayed in charts and graphs. In addition to SMS editing and admin functionality, the dashboard includes various functions including delivery settings, send list management and delivery status analysis.

On January 30, 2023, Rakuten Mobile rolled out the full-scale launch of the Rakuten Mobile Business Plan, a mobile carrier service for business customers. With Symworld™ CPaaS SMS API and more, the company will continue to further strengthen its service offerings for business customers.

Rakuten Symphony is globally deploying open-interface communication platforms based on its track record of building state-of-the-art infrastructure. SMS is characterized by high delivery and opening rates, and in addition to its convenience for business, Rakuten is developing this service because demand is increasing for SMS as an emergency contact measure. Symworld™ CPaaS SMS API was launched by Rakuten Symphony in July 2022 and has already been deployed by several companies.

Rakuten Mobile and Rakuten Symphony will continue to support efforts to improve corporate productivity and operational efficiency through the development and provision of high-quality services that meet the diverse business needs of customers.
