Urgent! Just received a telecom message to reset the password. What happened?

Dear telecom users, hello! First of all, thank you for your support to China Telecom. Generally, the following reasons are received: the mobile phone sends a short message instruction to reset the customer password to the system, and then the system will send the short message content of resetting the customer password to your mobile phone; In addition, if you contact our customer service staff and say that you have forgotten your password, the staff will also send you a short message on how to reset your password. If you don't do it yourself, I suggest you check with your family or friends if you have sent similar text messages recently or contacted our customer service staff. If you have any questions, you can add 8000 10000 as a friend through QQ and enjoy the guidance and help of QQ customer service. You can also enter "@ Guangdong Telecom" in the Baidu search box of your mobile phone to get more communication information.
