The Sender ID appears correctly in your outgoing SMS report, but the handset displays a different one.

If there is a difference between the Sender ID displayed in the Outgoing SMS Report and on the recipient's handset, this indicates that the Sender ID is being replaced by downstream carriers, who may apply filtering or enforce delivery rules to ensure message completion.

Certain countries may modify the Sender ID due to local carrier regulations and compliance requirements.

Some carriers only permit numeric Sender IDs, while others may substitute an alphanumeric (custom word) Sender ID with one of their own.

Note: When a carrier overwrites the Sender ID, two-way messaging is not supported.
