Can't the SMS function be turned on after being hacked several times?

95% can't, because the role of blackening is to prohibit contact. Of course, the remaining 5% can be hacked because software, such as 360 and mobile phone housekeeper, can be sent after being hacked, and the original functions of mobile phones are hacked. A few mobile phones can be sent but not received after being hacked, and most of them can't be sent or received.
