What if there is no verification code?

First check whether the verification code is intercepted in harassment interception. If there is, go get it back. If not, check whether the cell phone signal is normal, and whether it is normal to receive other short messages or make phone calls. If not, find a place with good signal before accepting it. Third, check whether you have entered the wrong mobile phone number. The other party has sent the verification code, but it was sent to someone else's mobile phone by mistake.
