Case Study: Operator Collaboration Brings Major RCS Coverage to Japanese Market

September 11, 2018


Read our new Case Study to learn how operator collaboration brought major RCS coverage to the Japanese market.

When launching RCS, operators have several different architectural and handset coverage options to consider, each of which impacts the commercial offering, complexity of interconnect, and level of control the operator has over the customer experience. The Japanese operators have taken an original approach to this question.  KDDI Corp,, NTT DOCOMO, Inc. and SoftBank Corp. collectively launched RCS in May 2018, having collaborated to source a system based on unified specifications.

As a result, Japan became the first country in the world to enjoy RCS coverage with all major MNOs. Better still, this choice allowed them to achieve complete client and network interoperability without sacrificing control. The messaging service upgrade is named +Message, which by the end of August 2018, approximately three months after launch, had exceeded 3.0 million P2P customers.
