In light of the recent changes to the requirements for sending messages to Singapore, we have compiled some key points into a Frequently Asked Questions section.

All sender IDs must be registered to send SMS messages. Any unregistered sender IDs will result in those messages being blocked.

UK carriers take “smishing” (phishing via SMS) very seriously. Customers sending SMS messages after July 3, 2023, from sender IDs that don’t conform to the above requirements may incur liquidated damage charges of up to £5,000.

Several carriers in Sri Lanka only allow Alphanumeric preregistered sender IDs. All long codes or similar will be blocked. Messages sent from unregistered sender IDs will still attempt to be sent but will likely get blocked.
