Dear customers: China Mobile is making a star service plan. You are rated as an unrated star-rated customer, and you can enjoy 0 hours if your phone bill balance is less than that of 0 yuan.

1. This message seems to be sent by China Mobile to users. In other words, you are not the only one who received this message. It may be the mobile phone number of the city, or it may be the whole province or a certain region or a certain field.

2. This message tells you the user rating results inside the mobile phone. Generally speaking, if you use communication services, operators will evaluate your usage within a certain period of time, usually once every six months or once a year. Its evaluation conditions are comprehensive, such as your card use time and your consumption status. If you use this card for a long time or spend more every month, your rating will be higher.

3. There will be corresponding treatment after rating, just like the overdraft limit service in your SMS now. The overdraft limit of a mobile phone card is similar to that of a credit card, that is, you can use it without paying the phone bill first. If it gives you a limit of 100 yuan, you can use this number normally without stopping, provided that the arrears of your mobile phone do not exceed 100 yuan and the validity period does not exceed the specified time.

Judging from the rating message you received, it should be that you haven't used this number for a long time or your monthly consumption is not very high, so you didn't get the task level, so your overdraft limit is 0, which is probably what your message means.
