What software does Apple use to block incoming calls and text messages?

Hello, you are using the itunes version of the mobile phone housekeeper. Because harassment interception and other functions need to be controlled at the bottom of the system, you have to get permission after jailbreaking, and because these can't be online in the appstore, the itunes version of the housekeeper has no system-level functions such as interception. If your iphone has escaped from prison, I suggest you search for "Tencent" on Cydia and find the installation of Pro, the mobile phone housekeeper of Tencent.
