There has been no text message since Chongqing complained.

The short message function of mobile phone was shut down by operators, mainly because sending the same short message in groups was judged as spam by the system, or it was shut down because many people reported that the content of the short message was illegal.

Log in to the mobile online business hall and check the list of sent SMS numbers in the SMS list. If multiple short messages are sent at the same time, make sure they are not sent artificially, but may be sent by malicious software on the mobile phone. At this time, it is necessary to use anti-virus software to kill the virus in the computer, and at the same time limit the SMS sending authority of some software;

Call 10086 to ask the customer service how to restore the SMS function, or take the network ID card of the mobile phone card to the nearest mobile business hall to restore the SMS function. If you can't recover, you can consider getting a new SIM card.
