Why is there a text message informing me that I have a phone call after I call?

Nowadays, many of them are smart phones. It is possible that what software is installed in your mobile phone is searched by voice hot words and will be automatically sent to the service desk, so you will receive SMS notification. Suggestion: Call the service desk of China Mobile or China Unicom (depending on the card you use) and switch to manual service. Then, ask the service desk to check the SMS number you received to find out what service you can provide. If you don't need it, I'll cancel it for you
