The SMS template cannot be reviewed.

You are referring to the text message content that you submitted on the text message platform, and then clicked to send, but it could not be submitted. If this is the case, it should be that the text message content contains sensitive characters. I suggest you can Work with your SMS provider to test which words cannot be sent, and then modify them. If these methods still don’t work, it is recommended that you use the OneSMSer SMS platform, which has fewer sensitive words and is easier to operate. There are also many signatures in the business report, which is enough to send a lot of information that will not be blocked.
