Is the written notice of China Southern Power Grid Examination sent by SMS?

According to the test records of previous years, China Southern Power Grid generally informs candidates to take the written test by SMS. The contents of the notice generally include:

Your company name, written test time, written test place, contact information of the person in charge, and the content of "name+phone number+whether to take the test" to the person in charge after receiving the text message.

Small partners who take exams in China Southern Power Grid must pay attention to SMS notification in time. Generally, it takes about one month from the registration delivery time to the announcement time.

I wish the majority of candidates a smooth customs clearance!
