What should I do if my personal information disappears after the PDA is updated?

The failure to receive SMS verification code for a long time may be caused by the following reasons: First, the number of times of collection exceeds the limit. Solution: I can only get the verification code 20 times a day. If I exceed the number of times today, please try again tomorrow. Second, the mobile phone business does not support the solution: at present, the number segments of the three major mobile operators in China 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. Reason 3: Mobile phone security software interception (for smartphone users who have installed security software) Solution: Open the mobile phone security software, temporarily turn off the interception function, and then try to obtain the verification code again. Reason 4: SMS gateway is congested or abnormal.
