The driving test appointment was successful, but I didn't receive the text message.

I didn't receive the scheduled message. Sometimes the screening function is set on the mobile phone, and the SMS screening function is cancelled, depending on whether the mobile phone is in arrears. Sometimes the network platform of the vehicle management office will have problems. The most important thing is to find your mobile phone problem first, which is the SMS blocking function. Make sure it's not a cell phone problem and there's no arrears, then it's a network problem at the DMV. If the above can't be solved, you can only go to the Internet Pre-test Center of the Vehicle Administration.
