A mass message was sent on the short message platform at 5 pm. Why didn't anyone receive it?

There are many reasons why you can't receive text messages. After normal operation and maintenance, the platform reading SMS verification code will generally summarize the following reasons for not receiving SMS:

First, adding punctuation or spaces in the middle of keywords is not effective.

Third, removing keywords has a good effect.

Fourthly, when using digital mask, the number is changed to full-angle number, and the effect is good.

5. Correct format: SMS text+SMS signature;

Sixth: Chinese format must be used, not English []. Channel does not support [] as a signature symbol, [] will fail.

Seventh, the SMS signature should be in front of or behind the SMS according to different operators, so as to avoid multiple signatures for one content, otherwise it will be invalid.

Eighth: SMS signature, in principle, requires 3 to 8 words in Chinese, involving business license, company name, keywords or related business.

Ninth: the signature is incorrect or the submitted SMS signature is inconsistent with the record, and the sending failed.
