Iphone will block calls from this number. What tips did the other party hear?

After adding a number to the iPhone to "block incoming calls from this number", the other party will hear the prompt tone of "The number you dialed is busy, please redial later", which is also commonly known as "black out". Blackening the number can effectively avoid SMS harassment and phone harassment.

The multi-touch and gesture control of iPhone is based on the technology developed by FingerWorks. The touch screen of iPhone has thermal function, and users can slide their fingers on the touch screen for mobile phone operation. Although the stylus can be used to touch the screen with the fingers of the iPhone, most gloves and stylus can prevent the necessary conductivity.

The iPhone screen can accommodate multiple icons, and users can turn pages left and right, but the icons on the Dock will not move with them. Users can move and delete instructions at any time by long pressing the third-party application, and can transfer some selected applications from iTunes. But Apple's default program can't be deleted.

IPhone has a built-in lithium battery, but unlike most mobile phones, users can replace the battery themselves. When the iPhone is connected to the computer, the iPhone 4s and previous models can be charged synchronously through the Dock cable, while the iPhone 5 and future models can be charged synchronously through the Lightening cable.
