Singapore Regulatory Compliance Maintenance - A2P SMS APIs - TLS 1.3 Requirement Apr 1, 2026 00:00-01:00 UTC

The Infocomm Media Development Authority (IMDA) of Singapore has mandated the use of TLS (Transport Layer Security) 1.3 for all API connections handling A2P SMS traffic, effective April 1, 2026.

To ensure compliance and prevent any possible service disruption, all customers sending SMS traffic to Singapore must update their systems to support TLS 1.3 before this deadline.

Sinch Platform Readiness:
Our commitment is to provide a secure and resilient infrastructure.
We have already enabled full TLS 1.3 support across our global A2P SMSC infrastructure. The final site, EU3 (IP 93.158.78.4), will be fully compliant to TLS 1.3 by end of February 2026, well ahead of the deadline.

Required Customer Action:
Verify Your Configuration: We strongly urge you to begin transitioning your systems to use TLS 1.3 for connections to Sinch immediately.

Compliance Deadline:
In accordance with IMDA requirements, connections using TLS 1.2 for traffic to Singapore should not be supported after April 1, 2026. To avoid any possible interruption of service to Singapore, you must complete your transition before this date.

Our team is ready to help ensure your transition is smooth and seamless.
Please do not hesitate to contact our customer support or account manager if you have any questions or require assistance.
