    Our provider has confirmed this is resolved, SMS sending has returned to normal expected behaviour. We are seeking more cause information from the provider to review if there is anyway Jomablue can be less affected by such upstream issues.

    The latest update from upstream provider:

    We are continuing to investigate an issue affecting outbound message delivery.
    As a precaution, new message submissions are currently paused while we stabilise the system. Our engineering teams are actively working to restore normal service. Further updates will follow as more information becomes available.

    We continue to monitor the situation with the upstream provider.

    There is no certainly yet that messages are being queued upstream so we still recommend avoiding SMS usage at this stage.

    Identified

    An upstream provider has confirmed an issue with SMS routing to telcos. Delivery is currently intermittent: some messages are delayed, some are not being delivered, and some may be received more than once. We suggest holding off on sending SMS for now, as delivery is unreliable at this stage. The provider is working towards a resolution and we are monitoring closely. We will post further updates as the situation progresses.
