Helping a Global Platform Deliver OTP Messages to Korean Users
A global CPaaS partner needed reliable OTP routing into Korea. SureM provided direct three-carrier integration (SKT · KT · LG U+), eliminating third-party hops and pushing inbox-arrival times under 3 seconds with carrier-confirmed delivery receipts.
Supporting RCS Campaigns for Korean Enterprise Messaging
A Korean retail brand wanted to upgrade marketing SMS to RCS with verified branding, rich cards, and interactive buttons. SureM ran RCS TrustMark onboarding and managed campaign delivery — lifting click-through rates and read confirmations dramatically.
Improving Delivery Reliability for Cross-Border Authentication Traffic
An overseas platform faced inconsistent OTP arrival on Korean carriers due to multi-hop routing. SureM rebuilt the path with direct local interconnects, retry policies, and DLR-based monitoring — lifting delivery to 99.4% and pulling latency under 3 seconds.
Case examples illustrate typical SureM engagements. Specific customer names and contractual details are kept confidential by request.Built for every messaging industry.
