Please note that if you’re trying to send an SMS to a country that doesn’t support Alphanumeric (custom word) Sender IDs, it will not be accepted by the carrier.

You will get an error response code back, and the delivery of the messages will fail.

Please refer to the article Global Sender ID Support for more information.

Alternatively, please create a ticket below to our support team, who will advise on the best Sender ID when sending to a specific country.
