There may be several reasons why Tongfang Wang Zhi Graduation Design Thesis Management System can't receive the verification code.

1, manage system channel congestion.

You can try again in half an hour.

2. The mobile phone number is wrong.

If you don't fill in the correct mobile phone number, the server can't send the verification code to your mobile phone, so you will not receive the verification code. You can enter the correct mobile phone number and try again.

3. The mobile phone is in flight mode or the operator's signal is weak.

Check whether the mobile phone is in flight mode, no network or search state, and select a place with network to receive the verification code. If this situation persists for a long time, it is recommended to replace the SIM card first and notify the operator to report the error. There is something wrong with the mobile phone, please change it.
