Collecting money, sending verification code failed.

Collect money. The reason why the verification code failed to be sent.

1, the mobile phone network signal is unstable, the received SMS number is wrong, and the SMS gateway is faulty.

2. The payee did not fill in the mobile phone number of the verification code correctly, or the mobile phone number being used at the time of collection is inconsistent with the mobile phone number filled in.

3. The payee's mobile phone number is blacked out by the blacklist of other applications, or the payee's mobile phone number has reached the upper limit of sending SMS.

4. SMS contains sensitive words and other reasons, which leads the service provider to refuse to send SMS.
