The mobile phone can't answer the phone, but it can answer and send text messages. What happened?

If the mobile phone operator has a signal problem, call the manual service desk at 10086 to tell them the symptoms of your mobile phone and ask them to reset any parameters for you. Restart your phone later, and it will be all right soon.

China Mobile can call 10086, China Unicom users can call 100 10, and telecom users can call customer service to confirm whether it is a signal failure.

Malware installed on the mobile phone will affect the acceptance of short messages or phone calls. Open the settings of mobile phone-application, check whether there is malicious software, and if there is, click Uninstall.

If the SIM card is loose, you can take it out with a card-taking pin and reinstall it. If not, you can try it on other mobile phones. If it doesn't work on other mobile phones, you need to change it in the business hall.
