Use-Case & Content Guidelines

Content Filtering

SMS contents may be modified, with brand names being removed or modifying some special characters such as "code," or adding random characters at the front of the message body, etc., in order to bypass the filtering and increase the delivery rate. For messages with OTP codes, it is also possible that the end users will receive a Text-to-Speech voice call delivering the OTP codes instead of receiving an SMS message.

Strongly recommend having your sender ID and contents registered to avoid any changes or delivery issues.
