If you submit your Sender IDs to SGNIC before Tuesday 17:00hrs, SGNIC will coordinate with the Participating Aggregators and Mobile Network Operators to effect the list the following Tuesday 10:00hrs, if there is no issue with the submitted data. For whitelist Sender IDs, please ensure that the path has been fully whitelisted before submitting the Sender IDs.
If you have an urgent need to remove a whitelisted Sender ID because SMS messages are dropping, you should cease the use of that whitelisted Sender ID until such time that either (i) the Sender ID has been offloaded from the Aggregators according to the schedule above, or (ii) the organisation’s investigation into the dropped messages has been successfully concluded.
Organisations are strongly encouraged to test the whitelist route using non-critical whitelist Sender IDs first, before placing mission critical whitelist Sender IDs into the Registry, and to confirm that the delivery route of their Sender IDs comprises entirely of Participating Aggregators.
