Liaoning Expressway can't receive the verification code.

The mobile phone is turned off, there is no signal for the time being, the payment is overdue, or the verification code and SMS are not received when it is stopped. It is recommended that you stop working due to arrears, and will generally resume within 24 hours after payment, basically within 24 hours. I suggest you change your mobile phone number or pick it up the next day.

It may also be that the interception software is installed on the mobile phone and the verification code cannot be received. I suggest you get rid of SMS interception of application software or try to change your mobile phone.
