Abnormal verification of Nantong Bai Tong verification code.

1, the number of acquisitions 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. Suggest trying to change another mobile phone number. Note: Some users with number portability are temporarily unable to receive short messages from third parties due to data interface changes. 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.

4. The SMS gateway is congested or abnormal. Solution: When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. I suggest you try again later.
