Is it true that the customs informed the letter of commitment after receiving the text message?

After receiving the short message, the customs informed that the undertaking was false.

First of all, the letter of commitment is informed by the administration. If you need to sign, download the form from official website, read it carefully and sign it. Secondly, the customs will not notify individuals by SMS or telephone. If there is any corresponding situation, official documents will be issued.

Therefore, it is recommended not to believe the content of such short messages easily. If you feel uneasy, you can consult the relevant official departments.
