Unable to send the appropriate service verification code.

Get too many times or the phone doesn't support it.

The failure to send verification code is mainly caused by the following reasons: 1, and the number of times of acquisition exceeds the limit. Solution: You can only get the verification code 20 times a day. If you have exceeded this number today, please try again tomorrow. 2. Mobile phone service is not supported. Solution: At present, all segments of the three major domestic mobile operators have been supported. However, mobile phone numbers in Tibet, Xinjiang, Hong Kong, Macao and Taiwan and overseas will be restricted by mobile phone service operators, so it is impossible to handle mobile telephone service. I suggest you try to change another mobile phone number. Note: Some number-carrying users are temporarily unable to receive short messages from third parties due to the change of data interface. Please call Netease customer service hotline for consultation. 3, mobile phone security software interception (for smart phone users who have installed security software). Solution: Open the mobile phone security software, temporarily turn off the interception function, and then try to get the verification code again.

A common verification code test is to let users input characters or numbers displayed on distorted pictures. Deformation is to avoid being automatically recognized by computer programs such as optical character recognition (OCR) and losing its effect. Because this kind of test is tested by computer, not by human like the standard Turing test, people sometimes call CAPTCHA the reverse Turing test.
