Description: Dear Customer,
We would like to inform you of an upcoming scheduled maintenance on July 9, 2025, from 20:30 UTC to July 10, 2025, 04:00 UTC, during which our network vendor will perform core network software upgrades.
There will be no service interruptions, but a temporary loss of resilience on SS7 signalling services will occur. Specifically, your SS7 signalling through our vendor’s Signal Transfer Point (STP) will continue to operate without backup protection during this time. It may impact SMS and Voice services, while data services will remain unaffected.
Thank you for your understanding. If you have any questions, please contact our support team.
Best regards,
Services Affected: Voice Services,SMS Services
