The star rating is determined according to the information such as network age, average monthly telephone bill, contract situation and overdue downtime, among which 10 is deducted for every two-way downtime during the evaluation period. In order to keep your star rating as low as possible, I suggest you save enough phone bills as much as possible to avoid downtime.
According to your score range, determine your star rating.
