Why is SMS notification intercepted by operators?

The format of the short message sent is incorrect.

Mass marketing SMS format: SMS signature+content+unsubscribe back to T, often users forget to add signature or the signature is incorrect and will be intercepted. If you send a notice, you can sign an exemption agreement without unsubscribing from T.

This short message contains illegal and sensitive content.

The content contains sensitive words, which will directly lead to the failure of sending short messages. Repeatedly emphasizing that the content involves pornography, gambling, drugs and other illegal nature will lead to the failure of the audit.

Message content or message signature is not reported.

In particular, the content of marketing short messages can only be sent to the short message channel after manual review, otherwise it will be intercepted. If the signature is not reported, it will also be intercepted by the operator.

It involves sending special industry marketing messages in violation of regulations.
