Mobile phone automatically sends text messages in the background.

The fee deduction service provided by the mobile phone system is a common problem of the cottage machine. Those charging service providers and manufacturers collude with each other. They pre-installed these numbers and software in their mobile phones. As long as there is a network, if you don't do anything in time, it will automatically order and steal the phone bill, which is a little worse than the charging software. So now I have to consider buying a cabin. If I want to buy it, I will give it a physical examination in advance.
