Zhixing could not receive the verification code when verifying the mobile phone number.

What you want to ask is why Zhixing can't receive the verification code when verifying the mobile phone number. Zhixing verified the mobile phone number and failed to receive the verification code. The phone stopped. Because Zhixing verifies the mobile phone number and sends a text message, check whether the mobile phone is down. If the phone is in arrears, you can't send and receive text messages, just pay the phone bill and reapply for the verification code.
