The mobile phone sends text messages automatically without knowing it.

A lot of traffic, text messages, phone calls, etc. Non-personal operation indicates that malicious software is installed in your mobile phone.

Sometimes it is difficult for us to distinguish these malware ourselves. It is recommended to go to the purchase office or mobile phone service station for help or brush the machine in time.

If you don't remove the malware, your number will continue to operate like this. In fact, the cost of SMS is not the most important. Sending it like this will bring you a lot of unnecessary trouble.

I hope my answer can help you, and I wish your mobile phone can get rid of malicious operation as soon as possible.
