Starting February 24, 2025, messages sent to the Philippines using unregistered Alphanumeric Sender IDs and international long codes will be intermittently blocked due to updated regulations aimed at reducing fraud. The blocked messages will not be sent later, although a failed messaging charges will still apply for these attempts.

To ensure uninterrupted messaging, you need to register your Alphanumeric Sender IDs before the final deadline on April 7, 2025, when all messages from unregistered IDs and international long codes will be permanently blocked. Unregistered messages sent before this date may also be filtered or replaced with a generic sender ID.
