What should I do if I make an appointment for a subject online, but I can't receive a text message?

First of all, make sure that the reserved mobile phone number is correct when making an online reservation.

Secondly, after confirming that the reserved mobile phone number is accurate; Please confirm whether the cell phone signal is normal? Are there any overdue downtime? If there is arrears of downtime after the appointment is successful, the mobile phone will not receive text messages during the downtime during the arrears period.

Thirdly, the mobile phone may be equipped with the function of blocking spam messages, and the SMS notification sent by the online booking platform may not be spam messages by default. You can check it in the blocked information of your mobile phone.

Finally, if none of the above happens, you can contact the local driving test center for confirmation.

It is also possible that there is something wrong with the online reservation system and the short message was not sent in time. The most effective way is to consult the local driver's license and start the relevant departments.
